Hay field near Fox River flats - Homer, <strong>Alaska</strong><br />

The <strong>Alaska</strong> <strong>Forage</strong> <strong>Manual</strong> was created through a joint agreement between the<br />

USDA Natural Resource Conservation Service (NRCS) and the <strong>Alaska</strong> <strong>Plant</strong> <strong>Materials</strong><br />

<strong>Center</strong> (PMC). The project was designed to synthesize and build upon existing information<br />

about forage crops in <strong>Alaska</strong>. A wealth <strong>of</strong> knowledge from many different<br />

sources has been compiled in this publication to serve present and future managers<br />

<strong>of</strong> livestock and wildlife operations, as well as local agencies.<br />

The goal <strong>of</strong> this manual is to introduce grasses, legumes and cereal crop species<br />

which are commonly planted to provide forage for grazing livestock. <strong>Forage</strong> species<br />

are those seeded on a pastureland and then grazed fresh or harvested for hay, silage<br />

or haylage.<br />

An important distinction can be made between pastureland and rangeland. Generally,<br />

pastureland is managed and agronomic inputs such as fertilizer and irrigation are<br />

applied to maintain native or introduced species. This is most <strong>of</strong>ten not the case with<br />

rangeland.<br />

For the purposes <strong>of</strong> this manual, <strong>Forage</strong> is defined as: “Herbaceous grasses and legumes<br />

available and acceptable to grazing animals, or that may be harvested for<br />

feed purposes” (TN <strong>Plant</strong> <strong>Materials</strong> NO. 28, 2001). Depending on location, climate,<br />

soil type, and management goals, a different forage species may be better adapted to<br />

the site than what was traditionally used.<br />

It is the authors’ intention that those who have traditionally used only brome and<br />

timothy as their primary forage species will consider trying something different with<br />

their next planting.<br />

Target Audience<br />

The intended audience for this manual is primarily<br />

managers <strong>of</strong> livestock and wildlife operations. This<br />

manual may also be useful to local organizations<br />

and government agencies interested in the conservation<br />

value <strong>of</strong> forage species. This book is prepared<br />

with the assumption that the primary goal <strong>of</strong><br />

planting will be to improve and increase forage for<br />

livestock or wildlife.<br />

Content <strong>of</strong> <strong>Manual</strong><br />

through sequential order from briefly introducing<br />

agriculture in <strong>Alaska</strong>, forage types and animals, and<br />

then proceeding to crop establishment and finally<br />

forage species pr<strong>of</strong>iles.<br />

Hay bales are stored in a pole barn in Delta Junction, to protect them from weather.<br />

Approximately 20,000 acres <strong>of</strong> hay are harvested each year in <strong>Alaska</strong>.<br />

<strong>Alaska</strong> is a vast state, with a diversity <strong>of</strong> environmental conditions. It is also an enormous<br />

state - 1/5 th the size <strong>of</strong> the contiguous lower 48 states. There is not an abundance<br />

<strong>of</strong> producing farmland, however. Of the 366 million acres in <strong>Alaska</strong>, about 900,000<br />

acres are farmland. The majority <strong>of</strong> this farmland - 737,746 acres, is used as pasture.<br />

From an agricultural standpoint, <strong>Alaska</strong> ranks near the bottom <strong>of</strong> U.S. agricultural<br />

production. The top 5 agriculture commodities reported in <strong>Alaska</strong> for 2010 were:<br />

Ag. Commodity Type Value <strong>of</strong> Receipts % <strong>of</strong> AK Total Farm Receipts<br />

Greenhouse/nursery $13.0 million 42.3%<br />

Regions<br />

For the purposes <strong>of</strong> this manual, <strong>Alaska</strong> is broken<br />

into several regions: Arctic, Western, Interior, Southcentral,<br />

Southwest and Southeast. These regions<br />

vary widely in climate. Agricultural lands are located<br />

in primarily two regions; the Matanuska and Susitna<br />

Valleys in Southcentral, and the Tanana Valley east <strong>of</strong><br />

Fairbanks in the Interior. The Matanuska Valley has<br />

mild summers and moderate winters, while the Tanana<br />

Valley is more extreme with hot summers and<br />

very cold winters.<br />

Major Agriculture Areas in <strong>Alaska</strong><br />

• Copper <strong>Center</strong> / Kenny Lake<br />

• Fairbanks<br />

• Delta Junction<br />

• Nenana<br />

• Talkeetna / Trapper Creek<br />

• Palmer<br />

• Wasilla / Point MacKenzie<br />

• Kenai<br />

• Homer<br />

Agricultural parcels in <strong>Alaska</strong> are clustered around the Matanuska, Susitna and Copper river drainages in the south and the<br />

Tanana and Yukon flats in the north. Farms also exist on Kodiak Island and on the Kenai Peninsula.


Agricultural parcels in Interior <strong>Alaska</strong> are centered around Fairbanks, Delta Junction, and Nenana.<br />

Agricultural parcels in Southcentral <strong>Alaska</strong> cluster around Palmer and Talkeetna, as well as Copper <strong>Center</strong> and Homer.<br />

<strong>Forage</strong> Types<br />

Photo: <strong>Alaska</strong> Division <strong>of</strong> Agriculture<br />

A farm near Palmer<br />

<strong>Forage</strong> crops can be consumed fresh when grazed by animals in a pasture setting.<br />

<strong>Forage</strong>s can also be harvested, cured, and preserved in many forms for future use.<br />

<strong>Forage</strong> can be baled into different shapes and sizes and/or stored as silage. Hay is a<br />

major source <strong>of</strong> fodder for the livestock industry during the dormant season.<br />

Animals prefer plants in the early growth stage (vegetative or boot) when the nutritional<br />

content <strong>of</strong> the plant is the highest. For hay and silage purposes, the best compromise<br />

between quality and yield occurs when the hay is harvested before flowering.<br />

The leaves <strong>of</strong> most forage species have the highest nutritional content. The stem<br />

is <strong>of</strong> lower quality due to higher concentrations <strong>of</strong> lignin, cellulose and hemicelulose.<br />

Crops for use as silage are placed in a pit or silo to begin the ensiling process. An<br />

anaerobic environment is necessary to maintain the good feed quality that can be<br />

achieved with silage.<br />

The period when forage is actively growing and nutritious in <strong>Alaska</strong> is considerably<br />

shorter than the lower 48, due to <strong>Alaska</strong>’s short growing season. Therefore the identification<br />

<strong>of</strong> species growth stages, and the proper timing <strong>of</strong> animal placement on pasture<br />

needs to be managed carefully. Improper management could result in a missed<br />

cutting for a hay crop, requiring supplemental feed to balance animal’s diet. Animals<br />

placed on the pasture when the forage conditions are least favorable (flowering, seed<br />

ripening stage) may not get the full nutrient potential <strong>of</strong> the forage crop.<br />

Grazing Pasture<br />

Hay Cropping<br />

Cattle graze on pasture land in Southcentral <strong>Alaska</strong>.<br />

Pasture is land with vegetation cover consisting<br />

<strong>of</strong> grasses and legumes used for livestock<br />

in a farm setting. Pastureland can also be used<br />

by wild animals for grazing or browsing purposes.<br />

In most cases, cultivated forage crops produce<br />

higher yields than most native forages.<br />

Crops are consumed during different stages <strong>of</strong><br />

growth.<br />

Control and regulation <strong>of</strong> grazing intensity,<br />

timing, frequency and selectivity are dictated<br />

by the producer to control the effects <strong>of</strong> grazing<br />

animals on plants (Holechek, Pieper & Herbel,<br />

2004, p. 127). A study from Owen et al. 1998<br />

found that a high intensity overgrazed pasture<br />

ultimately causes plant death. It was found that<br />

grasses can be grazed without damage if 50% to<br />

70% <strong>of</strong> the leaf and stem material by weight is<br />

left intact as a metabolic reserve. The remaining<br />

30% to 50% is considered “surplus” that can<br />

be consumed.<br />

Bales <strong>of</strong> hay typically contain 10 to 20% moisture.<br />

Hay is a major source <strong>of</strong> fodder for the livestock<br />

industry during the dormant season.<br />

Grasses, legumes, or other herbaceous plants<br />

are <strong>of</strong>ten used as a hay source. At roughly 25%<br />

moisture content - plants are cut, left to cure or<br />

wilt in the field and then processed into bales.<br />

Hay is then used as animal feed when grazing<br />

pasture is unavailable due to cold temperatures<br />

or when animals are kept in a barn or other enclosed<br />

area.<br />

Hay is sensitive to weather conditions which<br />

can play a large role in the quality <strong>of</strong> the product.<br />

If harvested in a drought year, plant quality<br />

and hay production may be diminished. In wet<br />

weather, the cut hay may spoil prior to baling<br />

or develop rot and mold once baled. Potential<br />

toxins then become a concern, as animals can<br />

become sick if they are fed spoiled hay. Musty<br />

and/or mildewy odors indicate the presence <strong>of</strong><br />

mold within hay.<br />

Silage Cropping<br />

Haylage<br />

Silage is stored in an anaerobic environment to promote fermentation.<br />

Typical moisture content ranges from 40% - 60%.<br />

Ensiling is a process that involves taking fairly wet<br />

(moisture level between 40-60%) early growth green<br />

forage and putting it into silos or pits under airtight,<br />

anaerobic conditions. If moisture conditions get any<br />

higher, clostridial bacteria may grow. The harvested<br />

crop must be well chopped and placed in a pit and<br />

packed tightly together, driving out air so the anaerobic<br />

fermentation process can begin. Fermentation<br />

will produce lactic acid, converting the high moisture<br />

forage plants to a stored energy food source.<br />

Producers may choose to routinely produce silage,<br />

or produce silage only when field drying is difficult<br />

or impossible. A more informative in-depth article<br />

about the ensiling process was written by the Iowa<br />

<strong>State</strong> University - Cooperative Extension Service,<br />

and can be located at the following address: www.<br />

extension.iastate.edu/Publications/PM417H.pdf.<br />

These large hay bales have an average moisture content<br />

between 20% and 40%. These bales are known as haylage or<br />

sometimes called ‘Sweet Hay’.<br />

The ensiling process for haylage follows silage and<br />

only really differs in the lower moisture content.<br />

Crops are ensiled at 20-40% moisture. Slight variations<br />

in moisture percentage may affect the desired<br />

outcome. When moisture content at harvest time<br />

is too low, the crop becomes too dry for harvesting<br />

and storage <strong>of</strong> haylage. At this stage, making the<br />

transition to a hay crop is advised.<br />

Advantages<br />

• Lower chance <strong>of</strong> weather delays and weather<br />

related damage during harvest;<br />

• Lower field, harvest, and storage loss; and<br />

• Provides flexibility and is adapted for many<br />

feeding programs.<br />

Evaluating Silage<br />

Disadvantages<br />

• <strong>Forage</strong> content is high in moisture, resulting in<br />

heavier forage that is difficult to haul;<br />

• Specialized equipment for harvesting, storing,<br />

and feeding may be needed;<br />

• Potential for high losses if silage is not properly<br />

made; and<br />

• Quality decreases rapidly after the pit is opened.<br />

<strong>Forage</strong> and Animals<br />

Dairy cattle on a farm in the Matanuska Valley<br />

In this section, several classes <strong>of</strong> foraging animals and their basic nutritional requirements<br />

are discussed. Protein, carbohydrates, fats, minerals, and vitamins are<br />

a few nutritional components necessary for animals to function properly. Other factors<br />

such as body size, type <strong>of</strong> digestive system, and the size and shape <strong>of</strong> an animal’s<br />

mouth are also discussed.<br />

Classes <strong>of</strong> Animals<br />

Livestock can be divided into three groups based on the type <strong>of</strong> forages they consume;<br />

grazers, browsers, and intermediate feeders.<br />

9


Grazers<br />

This group <strong>of</strong> animal has a diet that is dominated<br />

primarily by various grass species. Cattle, bison, elk,<br />

and musk oxen are all considered grazing animals.<br />

Horses are also grazers, but have an enlarged cecum.<br />

As a consequence, horses have a considerably less<br />

efficient digestive system than other grazers. Horses<br />

have to consume 50-60% more forage in comparison<br />

to cattle to meet the same nutritional requirements.<br />

Browsers<br />

Browsing animals have a diet that consists primarily<br />

<strong>of</strong> forbs and shrubs. Moose, deer and domestic<br />

goats are the primary examples <strong>of</strong> browsing animals<br />

in <strong>Alaska</strong>. They utilize a variety <strong>of</strong> succulent forbs<br />

throughout the entire growing season and persist<br />

on tall growing woody species during the winter.<br />

Moose can be found browsing on grass hay bales,<br />

birch limbs, and spruce buds throughout the winter<br />

months.<br />

Intermediate Feeders<br />

The intermediate feeders group includes the caribou<br />

and reindeer. Feeding on grasses, forbs, and<br />

shrubs allows the intermediate feeder to adapt its<br />

feeding habits to take advantage <strong>of</strong> available forage<br />

throughout the year. This adaptation allows these<br />

animals to survive in <strong>Alaska</strong>’s diverse environment.<br />

Nutritional Components<br />

All animals require food to carry out bodily functions<br />

for growth and structure. <strong>Alaska</strong>’s extreme<br />

living environment can present unique nutritional<br />

challenges. Foraging animals in <strong>Alaska</strong> may be deficient<br />

in several minerals and vitamins. Animals require<br />

high energy and/or high quality feed in order<br />

to minimize stress and fight disease during the long<br />

winters. Therefore, it is important to have a basic<br />

knowledge <strong>of</strong> forage nutritional components that<br />

are essential to understanding an animal’s overall<br />

health and maintenance.<br />

Carbohydrates<br />

Carbohydrates are the basic energy source for<br />

all animals. There are two types <strong>of</strong> basic carbohydrates;<br />

those associated with cell content and those<br />

associated with the cell itself. Starches and sugars<br />

are found within the cell wall and are easily broken<br />

down by the digestive system. Cellulose and hemicellulose<br />

are found inside the cell and require microorganisms<br />

within the rumen or cecum to assist with<br />

digestion. Lignin is also found within the cell wall<br />

<strong>of</strong> a plant and cannot be fully broken down and digested.<br />

Lignin concentrations are typically higher in<br />

the stem <strong>of</strong> a plant as opposed to the leaf material<br />

and increases as the plant matures.<br />

Fats<br />

Range animals do not have the gastrointestinal system<br />

needed to break down fats, due to the absence<br />

<strong>of</strong> bile in the small intestine. Bile is produced by the<br />

liver and is the main component in the degradation<br />

<strong>of</strong> fat. A small amount <strong>of</strong> fat is necessary in an ungulates<br />

diet. Some fats can be found in the seeds <strong>of</strong><br />

plants such as corn, peanuts, and sunflowers. Fats<br />

have about 2.25 times the energy levels in comparison<br />

to carbohydrates, making them the main source<br />

<strong>of</strong> stored energy in range animals.<br />

Feeding a reindeer hand-harvested lichen at the UAF Reindeer<br />

Farm. The reindeer’s wide rounded muzzle allows them<br />

to selectively feed on available forage throughout the year.<br />

Protein<br />

Like carbohydrates and fats, proteins are composed<br />

<strong>of</strong> nitrogen, carbon, hydrogen and oxygen atoms.<br />

More specifically, they are composed <strong>of</strong> chains <strong>of</strong><br />

amino-acids called peptides. These peptides are responsible<br />

for carrying out many functions in an ungulate’s<br />

body, such as the production <strong>of</strong> enzymes, hormones<br />

and antibodies. Proteins cannot be stored in<br />

the animal’s body, so a consistent supply is required<br />

to maintain animal health.<br />

The nutritional composition <strong>of</strong> a plant cell (Van Soest 1982)<br />

Protein levels in actively growing plants are<br />

typically higher than during dormancy. Leaves <strong>of</strong><br />

grasses, forbs and shrubs contain higher concentrations<br />

<strong>of</strong> protein than other parts such as the stems.<br />

However, forbs and shrubs tend to have higher levels<br />

<strong>of</strong> protein on average in comparison to grasses.<br />

Minerals<br />

Minerals play an important role in many essential<br />

body functions, such as muscle movement,<br />

nerve transmission, and blood function. Mineral deficiencies<br />

can result in poor animal health, increased<br />

mortality, and low production. Minerals can be<br />

grouped into two separate categories: macro-minerals<br />

and micro-minerals.<br />

Calcium, phosphorus, potassium, magnesium,<br />

chlorine, sodium, and sulfur are the main<br />

macro-minerals needed by grazing animals. These<br />

minerals generally encompass less than 5% <strong>of</strong> an animal’s<br />

body. Micro-minerals/nutrients are required<br />

in substantially lower amounts in grazing animals<br />

than macro-minerals, making up <strong>of</strong> less than .01% <strong>of</strong><br />

an animal’s body. Micro-minerals required by grazing<br />

animals are iron, copper, cobalt, fluorine, zinc,<br />

molybdenum, selenium, and manganese.<br />

Selenium commonly creates more problems<br />

for range animal health than all other micro-minerals.<br />

Selenium deficiency can cause skin disorders<br />

and/or rapid hair loss in animals. Soils throughout<br />

<strong>Alaska</strong> typically contain lower amounts <strong>of</strong> selenium<br />

as compared to the western United <strong>State</strong>s, where<br />

selenium levels are higher.<br />

Vitamins<br />

Grazing animals require organic compounds<br />

such as vitamins to carry out essential bodily functions.<br />

Vitamins are separated into two different<br />

groups based on their solubility properties. Fat soluble<br />

vitamins such A, D, E, and K are stored in the animal’s<br />

body and used during periods <strong>of</strong> inadequate dietary<br />

supply. Water soluble vitamins, such as C and<br />

B complex, cannot be stored in the body and require<br />

a constant supply.<br />

Vitamin D is derived from sunlight. Deficiencies<br />

<strong>of</strong> Vitamin D are rare in the contiguous United<br />

<strong>State</strong>s, but can be a concern in <strong>Alaska</strong>. Vitamin E is<br />

obtained by consuming the leafy parts <strong>of</strong> a plant and<br />

is almost never deficient. However, in some cases<br />

foraging animals have displayed moderate to violent<br />

muscle spasms due to Vitamin E deficiency.<br />

Endophytes<br />

Endophytes are organisms that live inside<br />

plants; they can be bacteria, fungi, or nematodes.<br />

Many survive only inside living plants and are transmitted<br />

from mother plant to seed. There are endophytic<br />

fungi that have mutualistic associations with<br />

their plant hosts (benefiting both organisms), however,<br />

some <strong>of</strong> these fungi produce toxins. The toxins<br />

produced can discourage feeding and can weaken<br />

or kill grazing animals. Not all members <strong>of</strong> an endophyte<br />

species produce toxins; growing conditions<br />

and time <strong>of</strong> year can also affect toxin loads. Generally,<br />

toxins are at their highest concentration in the<br />

crowns and seed heads. Many <strong>of</strong> the toxins can persist<br />

in stored hay for several years.<br />

Symptoms <strong>of</strong> Endophyte Poisoning In Animals<br />

Clinical symptoms are related to the type <strong>of</strong><br />

toxin present. The ergot alkaloids present in fescues<br />

cause constriction <strong>of</strong> blood vessels; symptoms include<br />

elevated body temperature (animals may stand<br />

in water), increased respiration, excessive salivation,<br />

restricted blood flow, “fescue foot” (dry gangrene in<br />

extremities) in cold weather, “fat necrosis”, nervousness,<br />

arched back, reduced weight gain, lowered<br />

reproduction, reduced milk production, and roughened<br />

hair coat. Ergot alkaloids can also be present<br />

in perennial ryegrass. The predominant toxin is typically<br />

lolitrem B, a tremorgen that causes tremors and<br />

muscle spasms. Lolitrems are the cause <strong>of</strong> “ryegrass<br />

staggers,” a condition in which the animal displays<br />

outstretched neck and limbs, tremors, stiff limbed<br />

gait, reluctance or inability to rise, disorientation,<br />

reduced weight gain and reduced prolactin levels.<br />

Tremors and disorientation are more pronounced<br />

when animals are excited.<br />

How to Identify Endophyte Infected Grass<br />

Endophyte infection does not generally cause<br />

outward symptoms in host plants, though they may<br />

appear more vigorous than neighboring plants,<br />

or may experience less grazing pressure. In cases<br />

<strong>of</strong> isolated toxin production in a pasture, the area<br />

may be fenced <strong>of</strong>f or livestock may feed on limited<br />

quantities <strong>of</strong> infected grass. Toxin production <strong>of</strong>ten<br />

increases with plant stress (heat, drought, overgrazing).<br />

Lush growth from excessive nitrogen fertilization<br />

should be avoided. Avoid feeding crown tissue<br />

at any time <strong>of</strong> the year. Mow or graze infected areas<br />

before seed heads develop, since they can contain<br />

the highest concentrations <strong>of</strong> toxins.<br />

Infected pastures should be avoided in the<br />

late summer or early fall when toxin levels are high.<br />

In more extreme cases <strong>of</strong> high toxin loads or widespread<br />

toxin production, pastures may need to be<br />

killed and replanted. Pastures should NOT be replanted<br />

with lawn mixes (endophytes can be desirable<br />

to protect lawns). Many pasture grasses are<br />

tested for fungal endophytes. “E +” or “E -” labels<br />

on seed mixes indicate the presence or absence <strong>of</strong><br />

endophytes; other labeling systems indicate the<br />

percent <strong>of</strong> infected seed. There are also varieties <strong>of</strong><br />

pasture grass containing endophyte strains that do<br />

not produce mammalian toxins, these provide nutritional<br />

and survival benefits to the plant without risk<br />

Developing a forage management plan is a necessary first step in any operation.<br />

Attention to detail is essential, as you are working with biological processes that have<br />

specific timing and environmental requirements. Continuing management is also important,<br />

to deal with the wide range <strong>of</strong> conditions and problems presented by <strong>Alaska</strong>’s<br />

environment. This section details several important factors to consider, including site<br />

conditions, species selection, site preparation and various other agricultural practices.<br />

Goals and Objectives<br />

A grower bales hay in the Matanuska Valley.<br />

Goals can be distinguished from objectives in that a goal is an over-arching direction,<br />

and an objective is a specific measure taken to attain a goal. Goals will vary among<br />

managers depending on where the farm operation is located, type <strong>of</strong> animal, and the<br />

forage type desired. These three factors are correlated; the outcome <strong>of</strong> one may have<br />

an effect on the others. Stating goals early on will help in making good decisions and<br />

setting objectives as the planning process moves forward. A hay producer in Interior<br />

<strong>Alaska</strong> may have different objectives than one in Southcentral, despite having similar<br />

goals, due to climate and other factors.<br />

16


Evaluating Site Conditions<br />

Potential limiting factors that will affect forage establishment<br />

are extensive, and a complete discussion<br />

is beyond the scope <strong>of</strong> this manual. This publication<br />

focuses on the limiting factors that have been<br />

observed in <strong>Alaska</strong>, and other parameters important<br />

for successful forage establishment.<br />

<strong>Plant</strong> growth depends on temperature, nutrient/<br />

water availability, soil moisture holding capacity and<br />

the ability <strong>of</strong> plant roots to penetrate a given soil.<br />

<strong>Plant</strong> growth also depends on physical characteristics<br />

<strong>of</strong> the soil such as texture and structure.<br />

Soil Texture<br />

Soil is made up <strong>of</strong> mineral particles, organic matter,<br />

air and water. Soil texture is determined by the<br />

composition <strong>of</strong> soil, expressed as % sand, % silt, and %<br />

clay. Three classes <strong>of</strong> particle size are acknowledged<br />

with sands being the largest (2.0-.05 mm), silts (.05-<br />

.002 mm) intermediate in size, and clays (


Nutrients<br />

Nutrients can be classified as non-mineral and mineral<br />

nutrients (North Carolina Dept. <strong>of</strong> Agriculture).<br />

The best way to assess soil nutrient levels is through<br />

a lab soils test. Collecting soil samples will allow the<br />

soils lab to specifically tailor fertilizer ratios to the<br />

planting site. A listing <strong>of</strong> essential nutrients follows.<br />

Macro<br />

nutrients:<br />

Primary<br />

Nitrogen (N)<br />

Phosphorus (P)<br />

Potassium (K)<br />

Secondary<br />

Calcium (Ca)<br />

Magnesium (Mg)<br />

Sulfur (S)<br />

Micro / Trace<br />

nutrients:<br />

Boron (B)<br />

Copper (Cu)<br />

Iron (Fe)<br />

Chloride (Cl)<br />

Manganese (Mn)<br />

Molybdenum (Mo)<br />

Zinc (Zn)<br />

Non-Mineral<br />

nutrients:<br />

Hydrogen (H)<br />

Oxygen (O)<br />

Carbon (C)<br />

The application <strong>of</strong> fertilizer at the time <strong>of</strong> seeding<br />

may be necessary for some forage crops. Most<br />

commercial fertilizers meet minimum standards for<br />

quality. When problems do arise, they can usually be<br />

traced to the product becoming wet during storage<br />

or shipment.<br />

Fertilizer is described by a three number designator,<br />

referred to as N-P-K. These numbers refer to the<br />

percentages <strong>of</strong> three elements: nitrogen, phosphorus,<br />

and potassium, respectively. Therefore, 20-20-<br />

10 fertilizer contains 20% nitrogen, 20% phosphorus,<br />

and 10% potassium by weight.<br />

18<br />

Soil Structure<br />

The aggregation, or combination, <strong>of</strong> mineral soil particles<br />

(sand, silt, clay) is referred to as soil structure.<br />

The arrangement <strong>of</strong> soil particles create varying pore<br />

spaces that allow different quantities <strong>of</strong> moisture to<br />

be retained. This is referred to as the porosity <strong>of</strong> the<br />

soil, and will be noted on a soils test.<br />

Soil compaction is a condition where the pore space<br />

<strong>of</strong> the soil is reduced by pressure applied to the soil<br />

surface. Compaction compresses micropores and<br />

macropores, destroying the soil structure. This affects<br />

the uptake and movement <strong>of</strong> water and can inhibit<br />

plant and microbial growth. Breaking up compacted<br />

layers can be accomplished by mechanical tillage.<br />

Equipment should be operated along the contour to<br />

reduce the potential <strong>of</strong> water entering furrows and<br />

creating soil erosion problems.<br />

General fertilizer recommendations for <strong>Alaska</strong>,<br />

based on fields producing 2 tons per acre are as follows:<br />

Southcentral:<br />

Interior:<br />

Kenai<br />

Peninsula:<br />

140N-60P-120K lbs. / acre, with split<br />

application <strong>of</strong> Nitrogen (70 lbs. / acre in<br />

spring; 70 lbs. / acre mid-summer)<br />

120N-40P-20K lbs. / acre, with a dressing<br />

<strong>of</strong> 10 lbs. /acre elemental sulphur<br />

80N-40P-40K lbs. / acre,<br />

with a dressing <strong>of</strong> 32 lbs. /acre sulfur<br />

Application rates <strong>of</strong> fertilizer can be determined<br />

by taking soils tests and should be adjusted to the<br />

soil conditions present. Excessive fertilization can<br />

cause nutrient interactions and salt injury to occur.<br />

area contact the nearest Cooperative Extension <strong>of</strong>fice<br />

or the <strong>Plant</strong> <strong>Materials</strong> <strong>Center</strong>.

How soil pH affects availability <strong>of</strong> plant nutrients<br />

Soil pH - Acidity and Alkalinity<br />

Soil pH is a measurement <strong>of</strong> soil acidity and/or alkalinity<br />

and has a major effect on nutrient availability. It is<br />

based on a logarithmic scale from 0 to 14. A number<br />

less than 7 represents an acidic soil, with the acidity increasing<br />

as the pH value gets closer to zero. Basic or alkaline<br />

soils are characterized by pH values greater than<br />

7. Neutral soils are represented by a value <strong>of</strong> 7.<br />

Basic soils contain high amount <strong>of</strong> bases (calcium,<br />

magnesium, potassium, sodium, phosphates) and are<br />

generally found in arid and semi-arid climates. Acidic<br />

soils form in wetter climates where the bases have<br />

been leached through the soil pr<strong>of</strong>ile. Having an idea<br />

<strong>of</strong> the pH value <strong>of</strong> the soil will help with plant selection,<br />

as some species prefer more acid soils and others prefer<br />

more alkaline soils. To correct acidic (low pH) soils,<br />

a limestone application is commonly applied. Sulfur is<br />

usually used to mitigate overly basic soils.<br />

19

Topsoil<br />

The topsoil layer is a source <strong>of</strong> native seed, plant<br />

propagules, organic matter, and soil microbes which<br />

can enhance the quality <strong>of</strong> the substrate being planted.<br />

Top soil is a valuable resource in forage establishment,<br />

and should be preserved and/or salvaged<br />

when possible. However, the topsoil layer existing<br />

in undisturbed areas <strong>of</strong> <strong>Alaska</strong> is <strong>of</strong>ten very thin and<br />

therefore expensive to salvage.<br />

Principals <strong>of</strong> Archaeology, by T. Douglas Price, © 2007 McGraw-Hill, used with permission.<br />

The diagram shown above displays the typical diagnostic<br />

horizons within a soil pr<strong>of</strong>ile. The ‘A’ Horizon, also<br />

known as topsoil, is a mineral layer directly beneath<br />

the ‘O’ Horizon, a layer <strong>of</strong> decomposing organic material.<br />

The ‘B’ Horizon consists <strong>of</strong> an accumulation <strong>of</strong> Fe,<br />

Al, Si and humus. The ‘C’ Horizon is a layer <strong>of</strong> unconsolidated<br />

earthy material and s<strong>of</strong>t bedrock that underlies<br />

the uppermost horizons. The bottom strata consists <strong>of</strong><br />

rocky material and is referred to as the ‘R’ Horizon.<br />

Weed Control<br />

Weeds (unwanted or out-<strong>of</strong>-place plants) can exclude<br />

other species on a site because they are quick<br />

to germinate and establish. Weeds compete with<br />

forage seedlings for moisture, nutrients and light.<br />

This competition for resources can have several negative<br />

consequences, including weedy forage stands,<br />

increased time for crops to establish or even crop<br />

failure. Weed control is most critical during the first<br />

year <strong>of</strong> forage production. Planning a weed control<br />

strategy prior to and during seedling establishment<br />

is essential for a healthy forage stand.<br />

Methods that may be used to control annual and<br />

perennial weeds include tilling, mowing and application<br />

<strong>of</strong> herbicides. Excessive soil manipulation loosens<br />

the seedbed and dries the soil, so tilling should<br />

be done as close to planting as possible. Mowing<br />

should be done as close to the ground as possible<br />

and prior to weed species setting seed. Perennial<br />

weeds may require several cuttings. If the weed infestation<br />

is heavy, remove the remaining material<br />

left after mowing so that it does not smother the<br />

forage.<br />

Chemical weed control is meant to eliminate or reduce<br />

competition from weeds during the seedlings<br />

vegetative growth phase. Herbicide labels are legal<br />

documents providing directions on how to mix, apply,<br />

store, and dispose <strong>of</strong> herbicide. Always follow<br />

the product label when using an herbicide. The <strong>Alaska</strong><br />

Department <strong>of</strong> Environmental Conservation regulates<br />

pesticide and herbicide use within the <strong>State</strong>.<br />

The Pesticide Control Program for the <strong>State</strong> <strong>of</strong> <strong>Alaska</strong><br />

can be accessed at dec.alaska.gov/eh/pest/.<br />

The Department <strong>of</strong> Natural Resources / Division <strong>of</strong><br />

Agriculture (DOA) maintains the authority to regulate<br />

the entry <strong>of</strong> seeds, plants, horticultural products<br />

and products relating to (AS 03.05.010). Under this<br />

authority, the DOA has established seed regulations<br />

to prevent “prohibited” or “restricted” noxious<br />

weeds from being sold deliberately or transported<br />

as a contaminant above allowable tolerances (11 AAC<br />

34.020). It is important to be familiar with noxious<br />

weeds and to apply appropriate management practices<br />

to prevent these species from establishing in<br />

your forage crop. The listed “prohibited” and “restricted”<br />

noxious weeds are included in Appendix C.<br />

The current Seed Regulations can be found at dnr.<br />

alaska.gov/ag/akpmc/pdf/SOA-seed-regs.pdf.


Selection <strong>of</strong> Species<br />

Species selection is one <strong>of</strong> the most important criteria<br />

for a successful forage crop. The harsh and diverse<br />

environments <strong>of</strong> <strong>Alaska</strong> limit species growth<br />

and production potentials. Therefore, it is imperative<br />

that species and cultivars (varieties) chosen are<br />

winter-hardy and able to survive and thrive in the local<br />

environment.<br />

Climatic, topographic, and soil conditions should all<br />

be taken into account when selecting species. More<br />

importantly, the plant species should meet the needs<br />

<strong>of</strong> the animals that will be feeding on and inhabiting<br />

the site.<br />

Desirable species characteristics include site adaptation,<br />

palatability, resistance to grazing pressure, and<br />

nutritional value. The ability <strong>of</strong> a species to produce<br />

high yields and withstand competition is also highly<br />

valued. The <strong>Alaska</strong> <strong>Forage</strong> <strong>Manual</strong> includes pr<strong>of</strong>iles<br />

<strong>of</strong> 24 species <strong>of</strong> grasses, legumes, and grains that are<br />

adapted for forage use in various regions across the<br />

state.<br />

The final determinant to consider when selecting<br />

species is best summarized below:<br />

“Always assess the practical availability <strong>of</strong> potential<br />

species before selecting them. Adequate plant materials<br />

must be available, at the correct time, and at an<br />

acceptable cost.” (Whisenant, 1999)<br />

their ability to overwinter within the Interior <strong>of</strong> <strong>Alaska</strong>. The variety at right has<br />

been mostly winter-killed, and would not be a good choice to plant in this region.<br />

21


<strong>Plant</strong>ing Choice<br />

Seed<br />

Seeding is the most common technique for establishing<br />

herbaceous plants for forage and hay. Seed<br />

is readily available for many species, and is relatively<br />

easy and inexpensive to produce. Furthermore,<br />

seed is easy to collect, process, handle, and apply to<br />

a pasture by drill or broadcast methods.<br />

The objective <strong>of</strong> seeding is to place the seed where<br />

it is needed and in proper contact with the soil. The<br />

method and equipment used depend upon the plant<br />

species being seeded and the characteristics <strong>of</strong> the<br />

site, such as soil type and topography.<br />

Only drill seeding and broadcast seeding are discussed<br />

in this manual, as these are the two most<br />

commonly used methods for establishing forage<br />

crops.<br />

‘<br />

Causes <strong>of</strong> Seeding Failure<br />

<strong>Forage</strong> seeding can involve considerable uncertainty.<br />

An awareness <strong>of</strong> limiting factors pertaining to<br />

seeding is valuable, and can help to limit uncertainty.<br />

There are many planting details that should be understood<br />

to establish forage<br />

species for pasture, hay or silage<br />

purposes.<br />

A few reasons for seeding failure<br />

include seeding too early<br />

or too late in the season, poor<br />

seedbed preparation, low<br />

quality seed, or inadequate<br />

depth <strong>of</strong> seeding. Seeding too<br />

deep is a common mistake,<br />

and seeding depth should be<br />

closely monitored.<br />

A definitive seeding plan<br />

which addresses each <strong>of</strong> the<br />

considerations listed above is<br />

<strong>of</strong>ten the best guarantee <strong>of</strong> a<br />

successful seeding result.<br />

<strong>Plant</strong>ing Method<br />

Drill Seeding<br />

Drill seeding is the most widely used method for<br />

forage plantings. When drill seeding, furrows are<br />

created and the seed is placed in the soil furrow at<br />

a controlled depth and covered with a relatively precise<br />

amount <strong>of</strong> soil. Drill seeders are used most <strong>of</strong>ten<br />

in agricultural settings. The drill seeding method<br />

is considered by many to be the best method <strong>of</strong> distributing<br />

seed. It is an effective means for establishing<br />

a high yield stand, using a smaller amount <strong>of</strong> seed<br />

compared to the broadcast method.<br />

One type <strong>of</strong> drill seeder, the Brillion style, is <strong>of</strong>ten<br />

used for planting forage. This seeder has been successfully<br />

used on most soil types, except very gravelly<br />

soils. The Brillion seeder delivers the seed into the<br />

soil, packs the seed in place, and applies seed with<br />

high accuracy.<br />

Broadcast Seeding<br />

The broadcast method scatters seed on the soil surface,<br />

and relies on natural processes or harrowing to<br />

cover the seed. This is a common form <strong>of</strong> seeding<br />

because advanced equipment is not needed. Broadcasting<br />

is fast and is usually the least expensive form<br />

<strong>of</strong> seeding.<br />

In order for this method to be successful, the seedbed<br />

should be properly prepared and the seed covered<br />

after application. Predation <strong>of</strong> seed by animals<br />

and desiccation by wind and sun may result in lower<br />

germination rates.<br />

The recommended seeding rate for broadcasting is<br />

double that <strong>of</strong> drilling, due to the lack <strong>of</strong> application<br />

control and the potential for reduced rates <strong>of</strong> seed<br />

establishment and germination.<br />

Broadcasting includes aerial seeding, hydroseeding,<br />

and hand-held methods. Hand-held or hand-operated<br />

spreaders can be used on smaller sites effectively,<br />

due to their portability and speed. Hand operated<br />

spreaders can also be used for both seed and fertilizer<br />

application.<br />

Site Preparation<br />

Site preparation is a primary concern in establishing<br />

forage pasture and/or hay fields. This phase is the<br />

most labor intensive and energy consumptive, and<br />

<strong>of</strong>ten determines the success or failure <strong>of</strong> a planting<br />

initiative (Vallentine, 1989). The objective <strong>of</strong> site<br />

preparation is to create a series <strong>of</strong> micro-environments<br />

or safe sites where conditions are favorable<br />

for seed germination, establishment, and growth.<br />

The surface <strong>of</strong> the prepared seedbed should be<br />

smooth for drilling and rough for broadcast seeding.<br />

Agricultural rangeland drills operate efficiently on<br />

ground that is relatively flat and free <strong>of</strong> obstructions<br />

that may affect seed distribution and placement. If<br />

a site is not seeded immediately after preparation,<br />

erosion can become a concern. Roughening or scarifying<br />

the surface with a harrow, imprinter, or other<br />

implement will help prevent water from coalescing<br />

and forming rills.<br />

Prior to final seeding, a light disking will break up<br />

the soil crust and smooth the surface. If broadcasting,<br />

a small imprinter can be used to crimp the seed<br />

and create catchment sites for water. Germination<br />

and survival increase tremendously with proper site<br />

preparation.<br />

Procedures relying on mechanical equipment, such<br />

as disking, plowing, harrowing and subsoilers, are<br />

agricultural methods commonly used to prepare a<br />

seedbed. Using these tools, the soil surface is manipulated,<br />

existing vegetation that could compete<br />

with seedlings is killed, and the planting process is<br />

facilitated (Whisenant, 1999).<br />

The final mechanical operation should prepare a<br />

firm seedbed which allows water infiltration and provides<br />

good seed-to-soil contact (Whisenant, 1999). A<br />

loose, fluffy seedbed limits establishment by creating<br />

air pockets, soil moisture loss and allowing seed<br />

to settle too deeply.<br />

No-Till Seedbed Preparation<br />

An alternative method <strong>of</strong> seedbed preparation is<br />

the no-till method. This method moves away from<br />

the traditional practice <strong>of</strong> plowing a field before<br />

planting crops. Tilling or plowing turns over the soil<br />

and leaves it vulnerable to wind and water erosion.<br />

This can further lead to sediment, fertilizer, and pesticide<br />

run<strong>of</strong>f into nearby rivers, lakes and oceans.<br />

The objective <strong>of</strong> the no-till method is to minimize<br />

soil disturbance so the growing site can be as productive<br />

as possible. Crops are planted into previous<br />

crop residues or stubble. Soil erosion can be reduced<br />

and water infiltration may be improved. Additional<br />

benefits <strong>of</strong> the no-till method<br />

include the shading <strong>of</strong> new<br />

growth by stubble from the<br />

previous year’s crop as well as<br />

the retention <strong>of</strong> soil moisture.<br />

The no-till methods adoption<br />

may also require fewer passes<br />

over a field thereby limiting<br />

disturbance to the soil. A criticism<br />

<strong>of</strong> no-till is the reliance on<br />

chemical herbicides as well as<br />

the need for precision equipment,<br />

such as drill seeders.<br />

This practice can be cost prohibitive<br />

for many growers, especially<br />

those with small acreage.<br />

The ‘no-till’ seedbed preparation method limits soil erosion and helps retain moisture.<br />

1. Be free <strong>of</strong> construction debris;<br />

2. Have relatively few large rocks or objects;<br />

3. Be free <strong>of</strong> ruts and gullies;<br />

An Ideal Seedbed Should :<br />

4. Have the top two inches in a thoroughly tilled friable, non-compacted condition;<br />

5. Be scarified to a depth <strong>of</strong> 6 to 8 inches if heavily compacted;<br />

6. Be devoid <strong>of</strong> non-native established weeds. Competition from weeds is a common cause <strong>of</strong> seeding<br />

failure, because they compete with seedlings for moisture, nutrients, and light; and<br />

7. Be without a significant seed-bank <strong>of</strong> weedy species. Seed stored in the soil as hard or dormant seed<br />

may be viable and will germinate if the conditions are right. The presence <strong>of</strong> a nearby seed-bank<br />

<strong>of</strong>ten accounts for the surprise <strong>of</strong> a weedy species showing up on a site.<br />

24


<strong>Plant</strong>ing Time<br />

The optimal planting season is just before the longest<br />

period <strong>of</strong> favorable conditions. <strong>Plant</strong>ing times<br />

are determined by choosing the season when rainfall<br />

and temperatures are most favorable for seedling<br />

germination and establishment. Many sites dry<br />

quickly following spring melt, and precipitation is<br />

quite low in some regions <strong>of</strong> <strong>Alaska</strong>. A seeding time<br />

should be chosen that is the most advantageous to<br />

the seeded species.<br />

In <strong>Alaska</strong>, spring planting is best where the primary<br />

growing season occurs in the late spring and/or summer.<br />

Early planting allows a species stand to develop<br />

a strong root- and-shoot structure, resulting in a<br />

plant that is more “winter-hardy”.<br />

The following table approximates the end <strong>of</strong> planting<br />

season across several regions <strong>of</strong> <strong>Alaska</strong>. The earliest<br />

time to plant is when the snow melts and the site is<br />

accessible.<br />

Latest Date to Seed:<br />

Western <strong>Alaska</strong> August 15<br />

Interior <strong>Alaska</strong> August 15<br />

Southcentral <strong>Alaska</strong> August 31<br />

Southeast & Aleutian Islands Sept. 15<br />

ALPINE BLUEGRASS<br />

<strong>Forage</strong> Value<br />

Alpine Bluegrass produces high quality forage for most classes<br />

<strong>of</strong> livestock and wildlife. It provides an ample protein supply,<br />

but forage yields are usually moderate to low. This grass is<br />

palatable for both livestock and wildlife. Alpine Bluegrass has<br />

moderate digestibility in comparison with other forage grasses.<br />

Distribution and Adaptation<br />

A mature stand <strong>of</strong> Alpine Bluegrass<br />

Alpine Bluegrass<br />

Poa alpina (L.)<br />

Description<br />

Poa alpina (Alpine Bluegrass) is a cool season perennial bunch<br />

grass that grows in mountainous areas. It is relatively short,<br />

growing erect culms between 15 and 20 centimeters (6 to 8<br />

inches) tall. Alpine Bluegrass has short leaves, a tight crown,<br />

and an inflorescence that is from 2.5 to 5 cm (1-2 inches) long.<br />

Alpine Bluegrass is a pioneer species, and is usually long lived.<br />

The grass grows a small to medium seed and produces about<br />

1,070,000 seeds per pound <strong>of</strong> seed.<br />

Alpine Bluegrass can be found growing in sub-alpine to alpine<br />

regions throughout <strong>Alaska</strong>. It has a pH range <strong>of</strong> 5 to 7.2, and<br />

typically prefers moderately fine to moderately coarse textured<br />

or well drained soils. Alpine Bluegrass is not tolerant <strong>of</strong> highly<br />

saline or waterlogged soils, but it can withstand prolonged<br />

periods <strong>of</strong> drought. Alpine Bluegrass has low nutrient needs,<br />

and will tolerate most nutrient deficient soils.<br />

Culture<br />

Alpine Bluegrass seed should be planted ¼ to ½ inches deep<br />

in coarsely textured soils, and ¼” or shallower in finely textured<br />

soils. Seeding rates depend greatly upon soil type, moisture,<br />

and location. An average seeding rate for broadcasting is 4-8<br />

lbs/acre and 2-4 lbs/acre when drill seeding. When seeded<br />

in a mixture, apply at a rate <strong>of</strong> 4-6 lbs/acre. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary and/or applicable. Irrigation in<br />

combination with fertilization should increase overall yields.<br />

Uses<br />

Livestock: Alpine Bluegrass is palatable to all classes <strong>of</strong><br />

livestock, such as cattle, sheep and horses. However, it does<br />

not produce a large amount <strong>of</strong> forage.<br />

Wildlife: Alpine Bluegrass provides excellent forage for elk,<br />

deer, mountain sheep and bison. It is moderately palatable<br />

to all classes <strong>of</strong> wildlife, and is <strong>of</strong>ten used on big game ranges.<br />

Management<br />

Alpine Bluegrass is best suited for pasture land use but it does<br />

not respond well to heavy grazing, and new seedlings should<br />

be protected from grazing if possible. Little research has been<br />

done to examine the effects fertilizer and irrigation might have<br />

on Alpine Bluegrass yields. Alpine Bluegrass should not be<br />

grown in conjunction with Annual Ryegrass, as ryegrass has<br />

negative allelopathic effects. At the present time there are no<br />

known major pests that threaten Alpine Bluegrass.<br />

AMERICAN SLOUGHGRASS<br />

<strong>Forage</strong> Value<br />

American Sloughgrass is highly palatable and a valuable<br />

forage species. It has good energy and high protein value.<br />

American Sloughgrass is also know to contain high amounts <strong>of</strong><br />

nonstructural carbohydrates. Livestock and wildlife generally<br />

concentrate in the wet meadows and riparian areas where<br />

American Sloughgrass grows.<br />

Distribution and Adaptation<br />

American Sloughgrass grows wild in <strong>Alaska</strong> and the northern<br />

United <strong>State</strong>s in wet meadows, marshes and swamps. It is<br />

also grown and used as forage in parts <strong>of</strong> Europe and Russia.<br />

American Sloughgrass generally prefers a pH ranging from 5.5<br />

to 7.5. It is commonly found growing in areas that receive at<br />

least 30 inches <strong>of</strong> precipitation per year.<br />

A mature stand <strong>of</strong> American Sloughgrass<br />

American Sloughgrass<br />

Beckmannia syzigachne (L.)<br />

Description<br />

Beckmannia syzigachne (American Sloughgrass) is a short<br />

lived perennial grass that is commonly found in shallow<br />

marshes or sloughs. Its shallow root system supports a leafy<br />

stem which may be up to 45 centimeters (18 inches) tall.<br />

Branched inflorescence, classified as closed panicle. Spikelets<br />

have very short pedicels that are arranged on only one side <strong>of</strong><br />

the panicle. One or two flowered spikelets disarticulate below<br />

the glumes. There are approximately 1,270,000 American<br />

Sloughgrass seeds per pound <strong>of</strong> seed.<br />

Culture<br />

An average broadcast seeding rate for American Sloughgrass<br />

is 10 lbs/acre. A rate <strong>of</strong> 5 lbs/acre is used when drill seeding,<br />

or when seeded in a mixture. American Sloughgrass seed<br />

should be planted to a depth <strong>of</strong> 1 /4 - 1 /2 inch. Be mindful <strong>of</strong> this<br />

grass’s high water requirement when choosing a growing site.<br />

If the planting site is dry at the time <strong>of</strong> seeding, irrigation may<br />

be necessary. American Sloughgrass seed should be planted<br />

in moist to wet soils that are <strong>of</strong> medium to fine texture. All<br />

seeding rates are determined by using Pure Live Seed (PLS)<br />

calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied.<br />

Uses<br />

Livestock: American Sloughgrass can be used for hay<br />

meadows or pasture land. It is highly palatable to all classes <strong>of</strong><br />

livestock, such as cattle, sheep and horses.<br />

Wildlife: American Sloughgrass is an important component<br />

<strong>of</strong> <strong>Alaska</strong>n wetland environments. The grass provides shelter<br />

and food for wildlife such as waterfowl, songbirds and various<br />

small mammals.<br />

Management<br />

American Sloughgrass normally produces an abundance<br />

<strong>of</strong> seed that will readily germinate upon reaching a suitable<br />

growing site. It can be feasible to use American Sloughgrass<br />

on seasonally inundated sites where grain production is<br />

unpredictable. American Sloughgrass’s vigorous growth habit<br />

is suited to sites where temporary, yet productive, cover<br />

is desired. The seed unit that falls from the inflorescence<br />

at maturity is a firm, free flowing spikelet that presents no<br />

difficulties for conventional planting equipment.<br />

ANNUAL RYEGRASS<br />

Photo: <strong>Alaska</strong> PMC<br />

<strong>Forage</strong> Value<br />

Annual Ryegrass produces good quality forage for most<br />

classes <strong>of</strong> livestock and wildlife. It is considered to have<br />

high palatability for grazing animals and low palatability for<br />

browsing species. This grass has a moderate digestibility, and<br />

makes an excellent forage crop when planted with legumes.<br />

Distribution and Adaptation<br />

Annual Ryegrass can be found growing throughout most<br />

<strong>of</strong> North America. Introduced from Europe, it is adapted to<br />

cool moist climates, like those found in the Pacific Northwest.<br />

Although it can be found growing in <strong>Alaska</strong>, it will not persist<br />

due to its inability to over winter in harsh climates. It can<br />

tolerate a pH range <strong>of</strong> 5 to 8, and typically prefers moderately<br />

course to moderately fine textured soils. Annual Ryegrass<br />

will not persist during prolonged periods <strong>of</strong> drought, but it<br />

will tolerate areas <strong>of</strong> high moisture. This grass can withstand<br />

highly saline and nutritionally deprived soils.<br />

A mature stand <strong>of</strong> Annual Ryegrass<br />

Annual Ryegrass<br />

Lolium multiflorum (L.)<br />

Description<br />

Lolium multiflorum (Annual Ryegrass) is an annual, coolseason,<br />

introduced bunch grass. This grass grows erect or<br />

decumbent culms between 30 to 60 centimeters (12 to 24<br />

inches) tall. Annual Ryegrass’s foliage is usually glossy and<br />

produces a spike inflorescence that is between 7 to 15 cm (3 to<br />

6 inches) long. As with most annual grasses, Annual Ryegrass<br />

produces a small root structure. This grass produces a medium<br />

size seed that grows at a rapid rate. Annual Ryegrass produces<br />

approximately 240,000 seeds per pound <strong>of</strong> seed.<br />

Always use ryegrass labeled for “forage or pasture use”.<br />

Some available varieties can be toxic. Non-forage types can<br />

contain harmful endophytes.<br />

Uses<br />

Livestock: Annual Ryegrass is used for pasture, hay, or silage.<br />

It is highly palatable to all classes <strong>of</strong> livestock, including cattle,<br />

sheep and horses.<br />

Wildlife: Annual Ryegrass is consumed by most classes <strong>of</strong><br />

large wildlife, such as bison, elk, deer, and mountain sheep.<br />

Small mammals and song birds will also utilize this grass when<br />

available.<br />

Culture<br />

Annual Ryegrass seed should be planted no deeper than ½<br />

inch in most soil conditions. It is commonly planted in mixtures<br />

with legumes or small grains. Annual Ryegrass seeding rates<br />

depend greatly upon soil type, moisture, and location. An<br />

average seeding rate for broadcasting is 8-16 lbs/acre and 4-8<br />

lbs/acre when drill seeding. When Annual Ryegrass is seeded<br />

in a mixture, apply at a rate <strong>of</strong> 6 - 10 lbs/acre. Seeding rates<br />

should be increased by 5 - 10 lbs/acre when planting on poor<br />

seedbeds or harsh sites. All seeding rates are determined<br />

by using Pure Live Seed (PLS) calculations, as described in<br />

Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary and/or applicable. Irrigation in<br />

combination with fertilizer should increase overall yields.<br />

Management<br />

Annual Ryegrass is excellent for temporary pastures or early<br />

growth on permanent pastures. This grass should be seeded<br />

with other pioneer grass species, due to its short life cycle.<br />

Annual Ryegrass will succumb to winters in <strong>Alaska</strong>. It is also<br />

prone to several types <strong>of</strong> rust disease, although the species is<br />

somewhat resistant. Annual Ryegrass requires ample moisture<br />

and irrigation should be applied when necessary.<br />

BEACH WILDRYE<br />

Photo: Brennan Veith Low, AK PM C<br />

<strong>Forage</strong> Value<br />

Beach Wildrye produces a moderate forage yield compared<br />

to other forage grasses such as Smooth brome or Timothy. Its<br />

palatability for browsers is moderate to low. Beach Wildrye<br />

provides moderate to low nutritional value, depending upon<br />

when it is cut or grazed. This grass is usually easily digested,<br />

but can cause impaction problems in horses if consumed when<br />

the moisture content <strong>of</strong> the grass is low.<br />

Distribution and Adaptation<br />

Beach Wildrye is adapted to tidal and coastal areas and can<br />

be found growing along the coast <strong>of</strong> <strong>Alaska</strong>. It prefers coarse<br />

textured, sandy and/or well drained soils. Beach Wildrye will<br />

grow well in soils with a pH between 6.0 and 8.0. This grass<br />

can tolerate excessively wet and droughty conditions, and can<br />

withstand saline soils.<br />

A mature stand <strong>of</strong> Beach Wildrye<br />

Beach Wildrye<br />

Leymus mollis (L.)<br />

Description<br />

Leymus mollis (Beach Wildrye) is a long lived, cool season,<br />

perennial sod forming grass. It grows erect culms 50 to<br />

60 centimeters (20 to 24 inches) tall, from long creeping<br />

rootstocks. Beach Wildrye produces stout, aggressive<br />

rhizomes, which increases its ability to spread. Leaves vary<br />

in length from 25 to 51 cm (10 to 20 inches), and are coarsetextured.<br />

The inflorescence is a stiff spike that is 10 - 25 cm<br />

(4 to 10 inches) in length and roughly 13 mm (½ inch) wide.<br />

Beach Wildrye produces a large sized seed (33,000 seed per<br />

pound) and has low seedling vigor and germination rate. A<br />

fifty percent germination percentage for Beach Wildrye seed<br />

should be considered acceptable.<br />

Uses<br />

Livestock: Beach Wildrye can be used for pasture or silage.<br />

It is moderately palatable to a select class <strong>of</strong> livestock, such as<br />

cattle. This grass can be useful forage if grazed or cut for silage<br />

at the optimum growth stage.<br />

Wildlife: Beach Wildrye is utilized by small mammals and<br />

song birds for forage and cover. Due to its limited range and<br />

moderate palatability, it is generally not consumed by large<br />

grazing or browsing animals such as moose, caribou, elk or<br />

bison.<br />

Culture<br />

Beach Wildrye is commonly grown by planting sprigs from<br />

existing plants. A sprig is the smallest division taken from a live<br />

plant to grow a new plant. Survival percentage is greater when<br />

Beach Wildrye sprigs are planted than from seed. If using seed,<br />

drill to a depth <strong>of</strong> ¼ to ½ inch. Seeding rates depend greatly<br />

upon soil type, moisture, and location. The seeding rates<br />

below only apply to ‘Reeve’ Beach Wildrye, and the European<br />

species Leymus arenarius. An average rate for broadcast<br />

seeding <strong>of</strong> Beach Wildrye is 60 lbs/acre, and 30 lbs/acre when<br />

drill seeding. Including Beach Wildrye seed in a mixture is not<br />

recommended due to its weak ability to compete with other<br />

plants. All seeding rates are determined by using Pure Live<br />

Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Beach Wildrye is highly responsive<br />

to nitrogen fertilizer. 20N-20P-20K fertilizer applied at a rate <strong>of</strong><br />

500 to 600 lbs/acre yield good results.<br />

Management<br />

Beach Wildrye may be severely damaged or destroyed from<br />

traffic that causes compaction. Digestive impaction may occur<br />

in horses if grazed when the moisture content is low. A fungus<br />

and pest called ergot can replace or destroy Beach Wildrye<br />

seed. Ergot occasionally occurs in many cereal crops and<br />

other various grass species. This fungus can be poisonous if<br />

consumed by animals and should be avoided.<br />

BERING HAIRGRASS<br />

<strong>Forage</strong> Value<br />

Bering Hairgrass produces good quality hay for most classes<br />

<strong>of</strong> livestock and wildlife. Hairgrass provides ample amounts <strong>of</strong><br />

protein, depending on its growing stage. Bering Hairgrass can<br />

provide good summer pasture forage, however most livestock<br />

find this grass unpalatable. As a result, an animal’s diet may<br />

consist <strong>of</strong> only 1-3% Bering Hairgrass.<br />

Distribution and Adaptation<br />

Bering Hairgrass has tufted leaves and a branched inflorescence<br />

Bering Hairgrass<br />

Deschamspia beringensis (L.)<br />

Description<br />

Deschampsia beringensis (Bering Hairgrass) is a<br />

highly variable, perennial, cool season bunch grass.<br />

The species grows from 50 to 60 centimeters (20<br />

- 24 inches) tall. Stems are erect, and the leaves are between<br />

1.5 - 4 mm (.06 and .16 inches) wide, flat or rolled. The leaves<br />

are mostly basal in a dense tuft. Bering Hairgrass’s inflorescence<br />

is a loosely branched, open panicle from 10 - 25 centimeters<br />

(4 to 10 inches) in length. There are two florets (flowers)<br />

per spikelet. Flowering occurs from May to September.<br />

Bering Hairgrass seeds mature from late June to late September,<br />

depending on location. Deschampsia beringensis produces<br />

approximately 1,360,000 seeds per pound <strong>of</strong> seed.<br />

Bering Hairgrass populations occupy moist to seasonally<br />

flooded, sunny environments. Bering Hairgrass is adapted<br />

to a pH range from 5.5 to 7.2. Salinity tolerance is generally<br />

low, but plants growing in coastal estuaries may be slightly<br />

more salt tolerant. Bering Hairgrass habitat includes coastal<br />

terraces, upper tidal marshes, seasonally wet prairies, and<br />

moist subalpine mountain meadows.<br />

Culture<br />

When planting Bering Hairgrass, seed should be planted<br />

¼ to ½ inch deep. Seeding rates depend greatly upon soil<br />

type, moisture, and location. An average seeding rate for<br />

broadcasting is 12 lbs/acre and 6 lbs/acre when drill seeding.<br />

All seeding rates are determined by using Pure Live Seed<br />

(PLS) calculations, as described in Appendix B, as described in<br />

Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary. Irrigation in combination with<br />

fertilization should increase overall yields.<br />

Uses<br />

Livestock: Bering Hairgrass can be utilized as hay or as<br />

a pasture crop. It is used by cattle, horses, and sheep. The<br />

palatability <strong>of</strong> Bering Hairgrass is moderate to low for most<br />

classes <strong>of</strong> livestock.<br />

Wildlife: A large variety <strong>of</strong> wildlife utilize Bering Hairgrass<br />

for cover. Most wildlife will not typically utilize the species as<br />

<strong>of</strong>ten as domestic livestock. Bering Hairgrass has moderate to<br />

low palatability for elk, bison and moose.<br />

Management<br />

Bering Hairgrass is adapted to coastal regions and is well suited<br />

for <strong>Alaska</strong>’s maritime environments. One should be aware<br />

that Bering Hairgrass grows aggressively and tends to compete<br />

with other grass species. Several diseases are associated with<br />

Bering Hairgrass, including ergot, stripe smut, blind seed and<br />

several turf diseases. Hairgrass is also vulnerable to several<br />

leaf spots and rusts. Insect pests such as aphids, billbugs,<br />

and leafhoppers can threaten stands <strong>of</strong> Bering Hairgrass, and<br />

should be monitored.<br />

BLUEJOINT REEDGRASS<br />

Photo: Casey Dinkel, AK PMC<br />

<strong>Forage</strong> Value<br />

Bluejoint furnishes excellent forage for livestock and some<br />

wildlife. As this grass matures, it quickly becomes tough and<br />

unpalatable, causing protein values to drop considerably and<br />

crude fiber content to increase. Bluejoint makes favorable hay<br />

and is palatable forage if managed properly. However, when<br />

putting effort and expense into seedbed preparation, one<br />

should consider growing more desirable forage grasses than<br />

Bluejoint Reedgrass. Seed availability is poor and prices are<br />

usually high for this species.<br />

Distribution and Adaptation<br />

Stands <strong>of</strong> Bluejoint can tolerate a thick build up <strong>of</strong> litter and<br />

mulch. This species can be found in highly organic peat and<br />

clay soils, but prefers a silty soil. Bluejoint is adapted to a wide<br />

range <strong>of</strong> temperatures (-40 °F to 105 °F) and precipitation<br />

regimes. It is extremely winter hardy.<br />

Bluejoint Reedgrass, Calamagrostis canadensis<br />

Bluejoint Reedgrass<br />

Calamagrostis canadensis (L.)<br />

Description<br />

Calamagrostis canadensis, Bluejoint Reedgrass is a tall, erect,<br />

cool season perennial grass that is found in wet meadows<br />

and prairies. The creeping rhizomes and rootstocks result<br />

in natural stands having a hummocky, uneven appearance.<br />

Erect culms are slender, not branched; grow to be 90 to 100<br />

centimeters (36 to 40 inches) tall. Leaves are bluish green,<br />

elongated and very narrow; rough to the touch. The caryopses<br />

are ellipsoidal, yellow-brown, smooth, and about .76 to 1.27<br />

mm (.03 -.05 inches) long. Inflorescence (seed-head) open<br />

panicle with single caryopsis borne in each spikelet (Barkley,<br />

1986). Bluejoint flowers from June to August and is a typical<br />

wind pollinated species like most grasses. Calamagrostis<br />

canadensis produces approximately 2,720,000 seeds per<br />

pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Bluejoint may be used for hay or pasture land.<br />

Cattle, sheep and horses find this grass highly palatable during<br />

early growth prior to seedhead formation.<br />

Wildlife: Bluejoint is utilized by bison, elk and deer, especially<br />

during the early portion <strong>of</strong> the growing season. It also has<br />

value as food and cover for waterfowl, small rodents, and<br />

some upland game birds.<br />

Bluejoint has broad ecological adaptations; occurring in a<br />

wide range <strong>of</strong> environments - from lowland wetlands to windswept<br />

alpine ridges. The species has a wide pH tolerance (pH<br />

4.5 to 8), from very acidic to moderately alkaline soils. Bluejoint<br />

can tolerate fresh to slightly brackish water.<br />

Culture<br />

An average broadcast seeding rate for Bluejoint is 6 - 8 lbs/<br />

acre. When drill seeding, 2 - 4 lbs/acre is appropriate. Fall<br />

seedings should be made at least 6 weeks before a killing frost<br />

is expected. Seedings should be drilled at a depth <strong>of</strong> 1 /4 inch<br />

and no deeper than 3 /8 <strong>of</strong> an inch if possible. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Bluejoint responds well to nitrogen,<br />

which has been shown to increase protein levels and overall<br />

forage yields. Pastures and hay fields should be irrigated when<br />

necessary. Irrigation, in combination with fertilization, should<br />

increase overall yields.<br />

Management<br />

Bluejoint is intolerant <strong>of</strong> heavy grazing and/or repeated<br />

harvests. Heavy trampling by livestock or wildlife can break<br />

the rhizomes and add to soil compaction in wetter areas.<br />

When over 40 percent <strong>of</strong> the plant is grazed, future yields can<br />

decrease by 15-20 percent. Harvesting should be restricted<br />

to a single cutting per growing season. When unfertilized and<br />

subjected to frequent grazing or harvest, Bluejoint stands are<br />

<strong>of</strong>ten damaged and persistence is poor.<br />

39


Fertilized stands <strong>of</strong> Bluejoint may produce 2 or 3 times more<br />

total forage than unfertilized stands. Also, fertilized stands<br />

can produce 10-20% higher protein yields and are considered<br />

more palatable for livestock and wildlife. Problems can occur<br />

with virgin stands <strong>of</strong> Bluejoint Reedgrass due to the large<br />

amount <strong>of</strong> surface debris that can accumulate from previous<br />

years’ growth. This hummocky layer can prevent top dressed<br />

fertilizers from reaching the living grass root zone. This layer<br />

can be removed by burning, blading, or mechanical mixing <strong>of</strong><br />

the surface organic layer.<br />

Grass<br />

Several potential pests have been associated with Bluejoint<br />

Reedgrass throughout the lower 48 states and parts <strong>of</strong> <strong>Alaska</strong>.<br />

The nematode Subanguina calamagrostis invades the leaf<br />

tissue <strong>of</strong> the grass, forming galls that cause the leaves to become<br />

twisted and contorted. A fungus, Dilophospora alopecuri, can<br />

then invade the leaves <strong>of</strong> Bluejoint Reedgrass, using the entry<br />

wound caused by the aforementioned nematode.<br />

KENTUCKY BLUEGRASS<br />

Photo: <strong>Alaska</strong> PMC<br />

<strong>Forage</strong> Value<br />

Kentucky bluegrass is excellent forage grass for most livestock<br />

and wildlife. It provides adequate nutritional value in the early<br />

spring before other plant species emerge. Once Kentucky<br />

bluegrass develops seed, the forage value and palatability<br />

drop considerably. Kentucky bluegrass is commonly used for<br />

pasture land, but considered undesirable for hay fields because<br />

<strong>of</strong> its low growth form, poor yield, and early maturity.<br />

Distribution and Adaptation<br />

Kentucky Bluegrass<br />

Poa pratensis (L.)<br />

Description<br />

Kentucky Bluegrass, Poa pratensis<br />

Poa pratensis (Kentucky bluegrass) is a perennial, cool-season,<br />

sod-forming grass native to Europe. This plant is about 45 to 60<br />

centimeters (18 - 24 inches) tall, although this height falls to 10<br />

to 15 cm (4 - 6 inches) when intensively grazed. Inflorescence<br />

(seed-head) has an open panicle and produces many small<br />

seeds. There are about 2,177,000 seeds per pound <strong>of</strong> seed.<br />

Leaves are from 15 to 30 cm (6 to 12 inches) long, and boatshaped<br />

(keeled) at the tips. Leaves are smooth, s<strong>of</strong>t, and about<br />

3 - 7 mm ( 1 /8 to 1 /4 inch) wide. Kentucky bluegrass becomes<br />

dormant during the heat <strong>of</strong> summer, but regains its green color<br />

in fall. Growth starts early in the spring. Tiller buds develop<br />

into stems or rhizomes. New rhizomes also arise from nodes<br />

<strong>of</strong> older rhizomes. Most rhizomes will penetrate 2 to 4 inches<br />

into the soil, but some go down more than 5 inches.<br />

Uses<br />

Livestock: Kentucky bluegrass is typically used for pasture<br />

land rather than as a hay crop, due to its shorter growing<br />

height. It is highly palatable to cattle, horses and sheep early<br />

in the spring, before other plants begin to grow. Kentucky<br />

bluegrass produces relatively low yields compared to other<br />

pasture grasses.<br />

Wildlife: Kentucky bluegrass is highly palatable to bison and<br />

elk. The tender plants are grazed immediately after growth<br />

begins, and the leaves remain succulent and green as long as<br />

soil moisture is present. Poa pratensis seeds are also eaten by<br />

several kinds <strong>of</strong> songbirds and rodents.<br />

Kentucky bluegrass is used throughout the U.S. It is best<br />

adapted to well-drained, fertile, medium-textured soils <strong>of</strong><br />

limestone origin. Performance on poorly drained and heavytextured<br />

soils is satisfactory. Favorable pH level for Kentucky<br />

bluegrass is between 6.0 and 7.5. Kentucky bluegrass grows<br />

best in humid areas. Optimum temperatures for forage production<br />

are between 60 °F and 90 °F. Kentucky bluegrass is<br />

essentially dormant during dry or excessively hot weather, allowing<br />

it to survive extreme temperatures. It grows best with<br />

direct sunlight, but will do well in the shade, so long as ample<br />

moisture and nutrients are available.<br />

Culture<br />

An average broadcast seeding rate for Kentucky bluegrass is<br />

6 - 10 lbs/acre; a rate <strong>of</strong> 2 - 4 lbs/acre is used for drill seeding<br />

or when seeded in mixtures. All seeding rates are determined<br />

by using Pure Live Seed (PLS) calculations, as described in<br />

Appendix B. Kentucky bluegrass seed should be planted to a<br />

depth <strong>of</strong> 1 /4 inch to 1 /2 inch.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. A pasture containing Kentucky<br />

bluegrass should be irrigated when necessary. Irrigation in<br />

combination with fertilization should increase overall yields.<br />

Management<br />

Proper fertilization and liming are the most important phases<br />

<strong>of</strong> Kentucky bluegrass management. For pastures, grazing<br />

should begin when grass is about 5 inches tall. Kentucky<br />

bluegrass should not be grazed shorter than 1- 1 /2 to 2 inches.<br />

Otherwise, sod will become weedy and unproductive. When<br />

overgrazed, poor root and rhizome development occurs,<br />

allowing weeds and shrubs to invade the pasture.<br />

Kentucky bluegrass is susceptible to attack by many diseases<br />

and insects. It is sometimes vulnerable to fungal infections,<br />

leaf spot, rust and powdery mildew. Depending on region,<br />

the grass is also susceptible to white grubs, billbugs, and sod<br />

webworms.<br />

MEADOW BARLEY<br />

Photo: Casey Dinkel, AK PMC<br />

<strong>Forage</strong> Value<br />

Meadow Barley produces a marginal amount <strong>of</strong> protein and<br />

is utilized most <strong>of</strong>ten by large grazing animals in the early<br />

spring. As with most grasses, nutritional value and digestibility<br />

diminish substantially after seed development or without<br />

adequate moisture.<br />

Distribution and Adaptation<br />

Meadow Barley has a narrow panicle with a purplish hue.<br />

Meadow Barley<br />

Hordeum brachyantherum (L.)<br />

Description<br />

Hordeum brachyantherum (Meadow Barley) is a short to<br />

intermediate lived, cool season, perennial bunch grass. It<br />

grows semi erect to erect culms 38 - 75 centimeters (15 to 30<br />

inches) in height. Leaves are green to bluish green, and are 3<br />

to 6.5 mm ( 1 /8 to 1 /4 inch) wide. The inflorescence, or seedhead,<br />

is a narrow panicle that is 2.5 - 10 cm (1 to 4 inches)<br />

in length and <strong>of</strong>ten <strong>of</strong> purplish color. This grass produces a<br />

medium sized seed with good seedling vigor. Meadow Barley<br />

seed possesses bristle like awns and non-viable florets that<br />

should be removed for easier seed flow through planting<br />

machinery. Seed per pound can vary widely depending upon<br />

the degree <strong>of</strong> seed conditioning. Bulky seed may contain<br />

30,000 to 100,000 seeds/lb, while highly processed seed can<br />

have upwards <strong>of</strong> 150,000 seeds per pound <strong>of</strong> seed.<br />

Meadow Barley is adapted to cool climates and can be found<br />

growing in wet meadows, salt marshes, along beaches, and<br />

riparian areas. This grass is adapted to finer textured soils<br />

like silts and clays but can also tolerate coarser textured soils<br />

that have adequate moisture. It prefers soils with a pH <strong>of</strong> 6.0 -<br />

8.5, and will not persist well in acidic environments. Meadow<br />

Barley has a moderate tolerance to drought conditions. It can<br />

also tolerate low nutrient and high saline soils.<br />

Culture<br />

Meadow Barley seed should be planted ¼ to ½ inch deep when<br />

drill seeded. This grass establishes easily and has high seedling<br />

vigor. Seeding rates depend greatly upon soil type, moisture,<br />

and location. An average seeding rate for broadcast seeding is<br />

4-8 lbs/acre, or 2-4 lbs/acre when drill seeding. When seeded<br />

in a mixture, apply at a rate <strong>of</strong> 4-6 lbs/acre. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary. Irrigation, in combination with<br />

fertilization, should increase overall yields.<br />

Uses<br />

Livestock: Meadow Barley can be used for pasture land or<br />

hay. It has moderate to low palatability for most classes <strong>of</strong><br />

livestock. Palatability is higher if grazed in early spring before<br />

setting seed. Meadow Barley starts its growth in the early<br />

spring and matures in early to mid September.<br />

Wildlife: Meadow Barley is considered to have low palatability<br />

for most large wildlife animals, such as elk, bison, and moose.<br />

However, deer are known to utilize Meadow Barley in the<br />

spring, when nutrient values are still high. Small mammals,<br />

song birds, and water fowl may use this grass for cover and<br />

food, throughout various stages <strong>of</strong> its life cycle.<br />

Management<br />

Meadow Barley is responsive to irrigation and should be<br />

irrigated if planted on drier sites. It does not respond well to<br />

heavy grazing and pasture deferment should be considered<br />

for healthy stands to persist. This grass may be susceptible<br />

to several fungal diseases such as head smut and/or leaf and<br />

stem rust. Meadow Barley’s bristly awn can cause harm to<br />

some animals by working its way into the nose, mouth, and<br />

intestine.<br />

MEADOW FOXTAIL<br />

<strong>Forage</strong> Value<br />

Meadow Foxtail produces moderate amounts <strong>of</strong> protein and is<br />

excellent quality forage for large grazing animals. It possesses<br />

good nutritional value and digestibility similar to that <strong>of</strong><br />

Timothy (Phleum pretense). Browsers such as moose do not<br />

find Meadow Foxtail to be as palatable as do grazing animals<br />

like cattle, bison and elk. As with most grasses, nutritional<br />

value diminishes substantially after seed development or<br />

without adequate moisture.<br />

Distribution and Adaptation<br />

Meadow Foxtail is adapted to cool, wet climates. It can be<br />

found growing in hay meadows, irrigation ditches, and along<br />

stream banks. Meadow Foxtail prefers fine-textured or poorly<br />

drained soils, such as silts and clays. This grass performs well<br />

in soils with a pH ranging from 5.8 to 8.0. Meadow Foxtail has<br />

a moderate tolerance to droughty and saline environments.<br />

Alopecurus pratensis can be found growing throughout most<br />

<strong>of</strong> <strong>Alaska</strong>, and portions <strong>of</strong> Canada and the United <strong>State</strong>s.<br />

Culture<br />

Meadow Foxtail, Alopecurus pratensis<br />

Meadow Foxtail<br />

Alopecurus pratensis (L.)<br />

Description<br />

Alopecurus pratensis (Meadow Foxtail) is a long lived, cool<br />

season, perennial bunch grass. It grows decumbent or erect<br />

culms 30 to 50 centimeters (12 to 20 inches) tall. Leaves vary<br />

in length from 5 to 30 cm (2 - 12 inches), and are roughly 6 to<br />

13 mm ( 1 /4 to 1 /2 inch wide). Meadow Foxtail’s inflorescence<br />

is a dense panicle and is 2.5 to 7.5 cm (1 to 3 inches) in length,<br />

and usually about 6 to 13 mm ( 1 /4 to 1 /2 inch) wide. This<br />

grass produces a medium size seed, which retains a hairy<br />

pubescence making it light and/or fluffy. Once established,<br />

Meadow Foxtail has high seedling vigor. Meadow Foxtail<br />

produces approximately 406,000 seeds per pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Meadow Foxtail can be used for pasture, hay, or<br />

silage. It is highly palatable to all classes <strong>of</strong> livestock, such as<br />

cattle, sheep, and horses. Meadow Foxtail starts its growth in<br />

early spring and provides livestock with adequate forage.<br />

Wildlife: Meadow Foxtail has moderate palatability for most<br />

classes <strong>of</strong> wildlife. Grazers such as elk and bison tend to select<br />

Meadow Foxtail more <strong>of</strong>ten than moose. It is also utilized by<br />

small mammals and song birds.<br />

Meadow Foxtail seed should be planted a ¼ to ½ inch deep,<br />

when drill seeded. This grass can be difficult to establish, but<br />

once in place seedling vigor is considered high. Seeding rates<br />

depend greatly upon soil type, moisture, and location. An<br />

average seeding rate for broadcasting is 4-8 lbs/acre and 2-4<br />

lbs/acre when drill seeding. When Meadow Foxtail is seeded<br />

in a mixture, apply at a rate <strong>of</strong> 4-6 lbs/acre. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary and/or applicable. Irrigation in<br />

combination with fertilization should increase overall yields.<br />

Management<br />

Meadow Foxtail makes an excellent pasture, hay, or silage<br />

forage crop. It is less winter-hardy than Smooth Brome (Bromus<br />

inermis) but is more tolerant <strong>of</strong> acidic soils. Meadow Foxtail is<br />

found in areas with milder winters and more acidic soils, such<br />

as the Kenai Peninsula. Meadow Foxtail can be problematic<br />

when planting with a drill seeder, due to the hairy pubescence<br />

that remains on the seed after cleaning. To reduce mechanical<br />

problems, Meadow Foxtail can be planted along with other<br />

grass or legume species. It responds well to grazing as long as<br />

there is ample moisture. At present, there are no major pests<br />

in <strong>Alaska</strong> that threaten Meadow Foxtail.<br />

POLARGRASS<br />

find Polargrass to be as palatable as grazing animals like cattle,<br />

bison and elk. As with most grasses, the nutritional value <strong>of</strong><br />

Polargrass diminishes substantially after seed development or<br />

without adequate moisture.<br />

Distribution and Adaptation<br />

Polargrass is adapted to cool, wet climates, and is found<br />

growing along rivers, meadows, tundra, fresh water marshes,<br />

and inland levees. It is adapted to cold boggy soils and/or<br />

mesic up lands. This grass will grow well in soils with a pH<br />

ranging from 4.9 to 6.8. Polargrass is intolerant to droughty<br />

and/or saline environments. It prefers northern latitudes and<br />

can be found growing in portions <strong>of</strong> Greenland, Canada, and<br />

<strong>Alaska</strong>.<br />

Polargrass, Arctagrostis latifolia<br />

Polargrass<br />

Arctagrostis latifolia (L.)<br />

Description<br />

Arctagrostis latifolia (Polargrass) is a long lived, cool season,<br />

perennial, sod forming grass. It grows erect culms 45 to 60<br />

centimeters (18 to 24 inches) tall. Polargrass leaves vary in<br />

length from a few inches to a foot and are usually 6 to 13 mm<br />

( 1 /4 - 1 /2 inch) wide. Inflorescence (seed-head) is narrow to<br />

somewhat open panicle 8 to 28 cm (3 to 11 inches) in length.<br />

Polargrass has low seedling vigor and produces a small seed<br />

with about 1,800,000 seeds per pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Polargrass can be used for pasture, hay, or silage.<br />

This grass is capable <strong>of</strong> generating high yields and can provide<br />

livestock with adequate forage and nutrition.<br />

Wildlife: Polargrass has shown to provide good forage for<br />

caribou and reindeer in northern regions throughout Canada<br />

and <strong>Alaska</strong>. Grizzly bears have been observed grazing large<br />

quantities <strong>of</strong> polargrass during spring and summer months. It<br />

also provides cover and forage for small mammals and various<br />

song birds.<br />

<strong>Forage</strong> Value<br />

Polargrass produces large amounts <strong>of</strong> protein and is a high<br />

quality forage for large grazing animals. It possesses good<br />

nutritional value and digestibility similar to that <strong>of</strong> Timothy<br />

(Phleum pratense). Browsers such as moose and deer do not<br />

Culture<br />

Polargrass seed should be planted ¼ to ½ inch deep. Low<br />

seedling vigor can make this grass difficult to establish. Seeding<br />

rates depend greatly upon soil type, moisture, and location.<br />

An average seeding rate when broadcasting Polargrass is 8 lbs/<br />

acre and 5 lbs/acre when drill seeding. Seeding Polargrass<br />

as part <strong>of</strong> a mix is not recommended because <strong>of</strong> the grass’s<br />

weak ability to compete with other plants. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary. Irrigation in combination with<br />

fertilization should increase overall yields.<br />

Management<br />

Polargrass seedling vigor is poor and early growth rates<br />

are usually slow. It requires an environment with low<br />

competition, moderate moisture, and adequate nutrients.<br />

However, once Polargrass is established, it has early and<br />

vigorous spring growth. Production trials <strong>of</strong> unfertilized vs.<br />

fertilized Polargrass have shown the differences in yield to<br />

be insignificant, suggesting that Polargrass does not respond<br />

well to commercial fertilizers. More research needs to be<br />

conducted to validate this theory, however.<br />

Polargrass requires moderate amounts <strong>of</strong> moisture and<br />

should be irrigated when applicable. Arctagrostis latifolia is<br />

an extremely winter hardy grass, with a greater tolerance to<br />

winter ponding and icy conditions than other forage grasses<br />

like Timothy (Phleum pratense) and Smooth Brome (Bromus<br />

inermis).<br />

RED FESCUE<br />

Photo: Brennan Veith Low, AK PMC<br />

<strong>Forage</strong> Value<br />

The forage value <strong>of</strong> Red Fescue ranges from fair to good,<br />

depending on geographic location. It possesses fair nutritional<br />

value, even after freeze-up, until snow becomes too deep for<br />

grazing. Red Fescue is also known to retain high protein values<br />

throughout its growth stage.<br />

Distribution and Adaptation<br />

Red Fescue is hardy, wear-resistant, and shade tolerant. This<br />

grass is adapted to wet, acidic environments. It prefers well<br />

drained soils with a pH between 5 and 7.5, but requires ample<br />

moisture to become established. Red Fescue is adapted to<br />

cooler zones.<br />

In areas <strong>of</strong> high temperatures and humidity, Red Fescue may<br />

turn brown or deteriorate during the summer months. This<br />

grass will generally recover in the fall when temperature and<br />

moisture conditions are more favorable. Red Fescue is highly<br />

competitive and is found all over North America.<br />

Red Fescue is a winter-hardy grass, adapted for use across <strong>Alaska</strong>.<br />

Red Fescue<br />

Festuca rubra (L.)<br />

Description<br />

Festuca rubra (Red Fescue) is a cool season, introduced, sodforming<br />

grass. Leaves <strong>of</strong> Red Fescue are bright green, wiry, and<br />

narrow. They are pressed together in a “V” shape and appear<br />

nearly round. Sheaths reddish or purplish at base, culms<br />

sometimes bent and growing to about 35 - 46 centimeters (14<br />

- 18 inches) tall. The inflorescence (seed-head) is a contracted<br />

and/or narrow panicle. Red Fescue produces about 410,000<br />

seeds per pound <strong>of</strong> seed.<br />

Culture<br />

When planting Red Fescue, seed should be planted ¼ to ½ inch<br />

deep. Seeding rates depend greatly upon soil type, moisture,<br />

and location. An average seeding rate for broadcasting<br />

Red Fescue is 12 lbs/acre and 6 lbs/acre when drill seeding.<br />

Seeding rate calculations are based on Pure Live Seed (PLS), as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Fertilization, combined with<br />

irrigation, may increase overall yields.<br />

Uses<br />

Livestock: Red Fescue is used for hay, pasture land, or silage.<br />

It is also utilized by cattle and horses. In some cases, Red<br />

Fescue will make up 10-15% <strong>of</strong> domestic sheep diets.<br />

Wildlife: Red Fescue is consumed by deer, moose, elk and<br />

a variety <strong>of</strong> other wild ungulates. It is also great forage for<br />

upland game birds and various species <strong>of</strong> water fowl such as<br />

the lesser Canada goose.<br />

Management<br />

One should be aware <strong>of</strong> Red Fescue’s aggressiveness and<br />

ability to out-compete other plants. It is not uncommon for<br />

Red Fescue to dominate a growing site even when planted in a<br />

mix with other grass species. This should be considered when<br />

formulating a forage seeding mix. Red Fescue can also be used<br />

to prevent the invasion <strong>of</strong> alders and willows.<br />

SIBERIAN WILDRYE<br />

Photo: Casey Dinkel, AK PMC<br />

<strong>Forage</strong> Value<br />

Siberian Wildrye has marginal forage quality. This grass<br />

also has poor digestibility due to large amounts <strong>of</strong> lignin,<br />

cellulose and hemicellulose. It has a protein content similar<br />

to Polar Brome (Bromus inermis), Slender Wheatgrass (Elymus<br />

trachycaulus), and Timothy (Phleum pratense), after the first<br />

year <strong>of</strong> establishment. Like most forage grasses, Siberian<br />

Wildrye nutrient levels are highest just before the plant<br />

develops its seedhead. There is limited Siberian Wildrye<br />

research data available concerning actual nutritional value,<br />

palatability, and grazing utilization.<br />

Distribution and Adaptation<br />

Siberian Wildrye seedhead<br />

Siberian Wildrye<br />

Elymus sibiricus (L.)<br />

Description<br />

Elymus sibiricus (Siberian Wildrye) is a tall growing, erect<br />

perennial bunchgrass, that grows from 75 - 90 centimeters<br />

(30 to 36 inches) in height. It is a cool season species native<br />

to fragmented intermountain areas. Siberian Wildrye can be<br />

easily identified by its long, lax, drooping seedhead. This grass<br />

species produces an abundance <strong>of</strong> seed, and has a conspicuous<br />

ability to grow in open, unshaded and infertile sites. Siberian<br />

Wildrye is known for its extreme winter hardiness and excellent<br />

seedling vigor. It produces approximately 127,000 seeds per<br />

pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Siberian Wildrye can be utilized as hay or as a<br />

pasture crop. It is used by cattle, horses, and sheep. The<br />

palatability <strong>of</strong> Siberian Wildrye is moderate to low for most<br />

classes <strong>of</strong> livestock.<br />

Wildlife: A large variety <strong>of</strong> wildlife utilize Siberian Wildyre<br />

for cover. Most wildlife will not typically utilize this grass for<br />

feed as <strong>of</strong>ten as domestic livestock. Siberian Wildrye has low<br />

palatability for elk, bison and various species <strong>of</strong> waterfowl.<br />

Siberian Wildrye is distributed across Europe, Asia, Russia,<br />

and parts <strong>of</strong> Canada and <strong>Alaska</strong>. It can be found growing in<br />

sandy soils, in areas receiving between 24 and 55 inches <strong>of</strong><br />

annual precipitation. Siberian Wildrye is a very drought<br />

tolerant species and will not grow well in wet areas or areas<br />

with poorly drained soils. The grass is adapted to slightly acid<br />

to neutral soils, with a pH range from 5.0 to 7.2. Siberian<br />

Wildrye will not tolerate saline soils or shaded environments.<br />

Culture<br />

An average broadcast seeding rate for Siberian Wildrye is<br />

12 lbs/acre. A rate <strong>of</strong> 6 lbs/acre should be used when drill<br />

seeding or when seeded in a mixture. Siberian Wildrye seeds<br />

should be planted at a depth <strong>of</strong> 1 /4 in. to 1 in. Seed should<br />

be planted in medium to coarse textured, well drained soil if<br />

possible. All seeding rates are determined by using Pure Live<br />

Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Little information is available<br />

regarding the effect fertilizer and irrigation may have on<br />

Siberian Wildrye yields.<br />

Management<br />

Siberian Wildrye appears to be a good forage species,<br />

although more research is needed to determine its overall<br />

value. There are several potential problems for growers<br />

dealing with Siberian Wildrye. This grass possesses a needle<br />

like appendage or awn that could potentially be harmful to<br />

livestock. Siberian Wildrye should not be grazed within the<br />

first year <strong>of</strong> its planting. Grazing could potentially destroy or<br />

diminish its life span. During its first year <strong>of</strong> growth, Siberian<br />

Wildrye does not produce a high overall yield. There has been<br />

little research into pests (such as insects, mildews, or rust) that<br />

could be harmful to Siberian Wildrye.<br />

SLENDER WHEATGRASS<br />

<strong>Forage</strong> Value<br />

Slender Wheatgrass is valuable forage for most classes <strong>of</strong><br />

livestock and wildlife. It is generally considered to have a good<br />

energy value and high protein content compared to other<br />

grasses. Slender Wheatgrass produces good quality hay if<br />

managed properly.<br />

Distribution and Adaptation<br />

Slender Wheatgrass is widely distributed across North<br />

America. Its range extends from <strong>Alaska</strong> to Newfoundland<br />

and south to North Carolina, Kentucky, Arkansas, Texas, and<br />

western Mexico. Slender Wheatgrass has been found growing<br />

at elevations from 4,500 to 12,000 feet. It prefers loams to<br />

sandy loams in areas receiving at least 14 inches <strong>of</strong> annual<br />

precipitation. Slender Wheatgrass is a drought tolerant<br />

species, but may still succumb to drought, since it sometimes<br />

matures later in the fall. The grass is adapted to slightly acid<br />

to slightly alkaline soils, growing in soils with a pH ranging<br />

from 5.6 to 9.0. Considerable genetic variability is present in<br />

Slender Wheatgrass populations, and some ecotypes may be<br />

rather specific to their original sites.<br />

Slender Wheatgrass seed head<br />

Slender Wheatgrass<br />

Elymus trachycaulus (L.)<br />

Description<br />

Elymus trachycaulus (Slender Wheatgrass) is an erect, tufted<br />

bunchgrass ranging in height from 60 to 70 centimeters (24<br />

to 30 inches). It is a cool season, perennial species native to<br />

the mountain and intermountain areas <strong>of</strong> the western United<br />

<strong>State</strong>s and the northern Great Plains. Slender Wheatgrass<br />

has very short rhizomes and the seedstalks and stems have<br />

characteristic reddish to purplish tinge at the base. It is seldom<br />

found in pure stands and is relatively short lived with a life<br />

expectancy <strong>of</strong> only 4-6 years. Slender Wheatgrass has about<br />

133,000 seeds per pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Slender Wheatgrass can be used for hay or pasture<br />

land. It’s highly palatable to cattle and sheep, and provides<br />

good quality animal fodder.<br />

Wildlife: Slender Wheatgrass is utilized by buffalo, elk,<br />

moose, mountain goat and dall sheep throughout <strong>Alaska</strong>. It<br />

is also used as forage and cover for some songbirds, upland<br />

game birds, small mammals, and waterfowl.<br />

Culture<br />

An average broadcast seeding rate for Slender Wheatgrass is<br />

10 lbs/acre, or 5 lbs/acre used when drill seeded or included<br />

in mixtures. Seeding depth should be 1 /4 to 3 /4 inch. Seed<br />

should be planted in fine to medium textured well drained soil<br />

if possible. All seeding rates are determined by using Pure Live<br />

Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures containing Slender<br />

Wheatgrass should be irrigated when necessary and/or<br />

applicable. Irrigation in combination with fertilization should<br />

increase overall yields.<br />

Management<br />

Slender Wheatgrass is best suited as a filler seed in mixtures<br />

containing slower establishing, longer lived grass species. It<br />

performs well when grown in combination with legumes.<br />

Slender Wheatgrass is moderately tolerant to grazing<br />

pressure, and requires good management to maintain stands.<br />

It is also considered to be a decreaser species on over grazed<br />

rangelands.<br />

When choosing Slender Wheatgrass as forage in <strong>Alaska</strong>,<br />

one should highly consider planting a cultivar or release that<br />

is adapted to the climate in which the plants will become<br />

established.<br />

Smooth Brome is resistant to drought and temperature extremes.<br />

Smooth Brome<br />

Bromus inermis (L.)<br />

Description<br />

Bromus inermis (Smooth Brome) is a sod-forming perennial<br />

cool season grass that spreads by rhizomes. Culms vary from<br />

30 to 45 centimeters (12 to 18 inches) in height on average.<br />

This plant produces numerous basal and stem leaves that<br />

vary in length from 10 to 25 cm (4 to 10 inches). Frequently,<br />

Smooth Brome leaves are marked by a transverse wrinkle<br />

resembling a “W” a short distance below the leaf tip. The<br />

inflorescence develops a characteristic rich purplish-brown<br />

color when mature. Brome seed is produced in semi-compact,<br />

127 mm (5 inch) long panicles with ascending branches. The<br />

flat compressed seed is usually awnless, about 8.5 mm ( 1 /3<br />

inch) long, and smooth. Smooth Brome is the most widely used<br />

<strong>of</strong> the cultivated brome grasses. It produces approximately<br />

142,000 seeds per pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Smooth Brome is used for hay, pasture, and/or<br />

silage. Cattle, sheep and horses find this grass highly palatable<br />

during the early growth stage, as well as late in the year after<br />

fall green-up.<br />

Wildlife: Smooth Brome is used by wildlife to varying degrees,<br />

depending upon the quality <strong>of</strong> the grass and the animal<br />

species. Elk and Bison use it as winter forage. Upland game<br />

birds and waterfowl use Smooth Brome for nesting cover and<br />

rearing their brood. Rodents such as voles and shrews use it<br />

for food and cover throughout the year.<br />

<strong>Forage</strong> Value<br />

If grazed before flowering, Smooth Brome is high in protein<br />

with relatively low crude-fiber content. <strong>Forage</strong> value decreases<br />

rapidly with maturity, once seed is produced. Northern<br />

varieties <strong>of</strong> Smooth Brome produce less forage on average<br />

than southern varieties, but are just as palatable for livestock<br />

and wildlife.<br />

Distribution and Adaptation<br />

Smooth Brome is adapted to cool climates. It is resistant to<br />

drought and extremes in temperature. It is a long lived grass,<br />

living 5 to 7 years on average, but can live as long as 10 years<br />

or more. This plant is very susceptible to disease in areas <strong>of</strong><br />

high humidity. Smooth Brome grows best on well drained silt<br />

and clay loam soils with high fertility. It will also grow well<br />

on lighter textured soils where adequate moisture and fertility<br />

are maintained. Smooth Brome performs best in a slightly<br />

acid to slightly alkaline environment (pH range <strong>of</strong> 6.0 to 7.5).<br />

Stands are difficult to obtain and growth is poor on soils high<br />

in soluble salts.<br />

Smooth Brome’s range <strong>of</strong> distribution is centered within the<br />

corn belt <strong>of</strong> North America and includes portions <strong>of</strong> Canada<br />

and <strong>Alaska</strong>. Depending on variety, this grass can grow in<br />

several regions <strong>of</strong> <strong>Alaska</strong>, as far north as Fairbanks.<br />

Culture<br />

Due to slow rates <strong>of</strong> germination and establishment, Smooth<br />

Brome requires a clean, firm seedbed. An average seeding<br />

rate for broadcast seeding is 20-25 lbs/acre, 10-15 lbs/acre<br />

when drill seeding. If seeded as part <strong>of</strong> a mixture, 5-10 lbs/<br />

acre should be used. When seeding in the fall, make sure to<br />

have seed in the ground at least six weeks prior to the first<br />

expected frost. Seedings should be drilled at a depth <strong>of</strong> 1 /2 to<br />

3<br />

/4 inch. All seeding rates are determined by using Pure Live<br />

Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios for Smooth Brome depend upon<br />

soil type, chemistry, and location. Soil samples should be<br />

collected and analyzed before fertilizer is applied. Pastures<br />

and hay fields should be irrigated when necessary and/or<br />

applicable. Irrigation, in combination with fertilization, should<br />

increase overall yields.<br />

Management<br />

Smooth Brome requires heavy applications <strong>of</strong> nitrogen<br />

in early spring and in fall to maintain high yields in a pure<br />

stand. Optimum forage production is obtained when brome<br />

is used in a planned cropping system and plowed out after 3<br />

to 4 years. Smooth Brome’s heavy sod makes it an excellent<br />

soil-conditioning crop, when included in cropping systems. In<br />

deep, well-drained soils it will root to 4 feet. Smooth Brome<br />

performs best in grassed waterways, field borders, and other<br />

conservation uses, where the forage can be cut and removed<br />

while in early bloom.<br />

55


Pastures should not be grazed prior to attaining a minimum<br />

height <strong>of</strong> about 10 inches at the beginning <strong>of</strong> the grazing<br />

season. Grazing pressures should be adjusted throughout the<br />

season to avoid grazing this grass below a minimum height <strong>of</strong><br />

4 inches.<br />

Grasshoppers and seed blight can be a factor during grass<br />

establishment, in semi-humid areas. Foliar diseases in humid<br />

areas have also been known to cause serious problems.<br />

Smooth Brome can be dramatically affected by seed midges,<br />

such as Stenodiplosis bromicola, in some northern areas.<br />

SPIKE TRISETUM<br />

<strong>Forage</strong> Value<br />

Spike Trisetum produces excellent quality forage for all<br />

classes <strong>of</strong> livestock and large wildlife, though it does not<br />

respond well to heavy grazing pressure. It is highly palatable<br />

to browse and grazing animals, and produces large amounts<br />

<strong>of</strong> protein in comparison to other grasses. Spike Trisetum has<br />

good digestibility and is considered to be an important grass<br />

for mountainous regions.<br />

Spike Trisetum<br />

Trisetum spicatum (L.)<br />

Description<br />

Trisetum spicatum (Spike Trisetum) is a relatively short-lived,<br />

cool-season perennial bunch grass. It grows erect culms 50<br />

to 75 centimeters (20 to 30 inches) tall. Leaves are usually<br />

flat to folded, and 2.5 to 13 cm (1 to 5 inches) in length. The<br />

inflorescence is also 2.5 to 13 cm (1 to 5 inches) long, narrow,<br />

dense, and sometimes purplish green. Spike Trisetum seed is<br />

small, with about 2,000,000 seeds per pound <strong>of</strong> seed. Spike<br />

Trisetum has a high root/shoot ratio in comparison with other<br />

grasses.<br />

Uses<br />

Spike Trisetum seed head<br />

Livestock: Spike Trisetum is commonly used for pasture. It is<br />

considered highly palatable for all classes <strong>of</strong> livestock. When<br />

used for hay, Spike Trisetum provides nutritious forage for<br />

cattle, sheep, and horses.<br />

Wildlife: Big game animals such as bison, elk, and deer,<br />

commonly utilize Spike Trisetum throughout its growing<br />

season. This grass is highly palatable to all classes <strong>of</strong> wildlife.<br />

Distribution and Adaptation<br />

Spike Trisetum is adapted to medium textured or well drained<br />

soils, and prefers a pH range <strong>of</strong> 4.9 to 7.5. It is found growing<br />

on drier areas <strong>of</strong> mountain meadows, roadsides, clear cuts,<br />

and is distributed almost worldwide. Spike Trisetum is tolerant<br />

<strong>of</strong> prolonged periods <strong>of</strong> drought or moisture, though it will not<br />

persist under conditions <strong>of</strong> high salinity.<br />

Culture<br />

Spike Trisetum seeds should be planted from ¼ to ½ inch deep.<br />

Seeding rates depend greatly upon soil type, moisture, and<br />

location. An average seeding rate for broadcast seeding is 6 -<br />

12 lbs/acre and 4 - 6 lbs/acre when drill seeding. When seeded<br />

in a mixture, apply at a rate <strong>of</strong> 2 - 4 lbs/acre. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Pastures and hay fields should<br />

be irrigated when necessary and/or applicable. Irrigation in<br />

combination with fertilization should increase overall yields.<br />

Management<br />

Spike Trisetum starts its growth in early spring. Like many<br />

grasses, its protein values diminish upon setting seed. Spike<br />

Trisetum does not respond well to heavy grazing pressure.<br />

Precaution should be taken not to over graze this grass. Spike<br />

Trisetum will stay green well into August or until covered by<br />

snow. It seldom occurs in dense stands, but usually cures well<br />

when cut for hay. Seed can be damaged more easily than most<br />

other grasses due to a liquid endosperm. Care should be taken<br />

when drill seeding to limit seed damage. At present, there are<br />

no known pests that are a concern for Spike Trisetum.<br />

TIMOTHY<br />

Photo: Casey Dinkel, AK PMC<br />

<strong>Forage</strong> Value<br />

Timothy produces good quality hay for most classes <strong>of</strong> livestock<br />

and wildlife. It also provides ample amounts <strong>of</strong> protein within<br />

the first 25 days <strong>of</strong> its growing cycle. Once Timothy is mature,<br />

crude protein values and digestibility diminishes greatly, a fact<br />

that should be considered when producing a hay crop. After<br />

the first hay cutting, Timothy can provide good late summer<br />

and early fall pasture forage.<br />

Timothy<br />

Phleum pratense (L.)<br />

Description<br />

Timothy seed head<br />

Distribution and Adaptation<br />

Timothy is adapted to a cool, humid climate. Timothy thrives<br />

in rich moist bottomlands and on finer textured soils, such<br />

as clay loams. It does not do well on coarser soils. Timothy<br />

prefers a pH <strong>of</strong> 5.5 to 7.0. Timothy will grow for a time on soils<br />

low in fertility, but it is better adapted to high fertile soil. It is<br />

not well adapted to wet, flat land where water stands for any<br />

considerable time, although it can withstand somewhat poorlydrained<br />

soils. Under conditions <strong>of</strong> limited moisture, Timothy<br />

performs poorly; it does not tolerate drought or prolonged<br />

high temperatures. Timothy is distributed throughout the<br />

entire United <strong>State</strong>s.<br />

Culture<br />

Phleum pratense, Timothy is a relatively short-lived, coolseason<br />

perennial bunch grass that grows in stools or clumps<br />

and has a shallow, compact, and fibrous root system. It grows<br />

in erect culms 50 to 100 centimeters (20 to 40 inches) tall.<br />

Leaves vary in length from 5 to 30 cm (2 to 12 inches) and are<br />

about ( 1 /4 inch) wide, narrowing gently toward the tip. Heads<br />

spike-like and dense, from 5 to 15 cm (2 to 6 inches) in length.<br />

The seed is very small and usually remains enclosed within the<br />

glumes. Timothy produces approximately 1,230,000 seeds per<br />

pound <strong>of</strong> seed. Timothy is different from most other grasses<br />

in that 1, or occasionally 2, <strong>of</strong> the basal internodes <strong>of</strong> the stem<br />

swell into a bulb-like growth. This characteristic is <strong>of</strong>ten used<br />

to identify the plant during its early stages <strong>of</strong> growth.<br />

Uses<br />

Livestock: Timothy is used for pasture and silage, but mostly<br />

for hay. It is palatable and nutritious for cattle and sheep, and<br />

also makes excellent hay for horses. Timothy is considered<br />

good forage for cattle and horses during the spring, summer,<br />

and fall. When being grazed by sheep it is considered good<br />

forage during the summer and fair during the spring and fall.<br />

Wildlife: Big game animals such as bison, elk and deer<br />

commonly utilize Timothy throughout its growing season.<br />

Some studies have shown that Timothy makes up to 20% <strong>of</strong><br />

bison and elk diets. Small mammals, song birds, upland game<br />

birds and waterfowl will also use Timothy for nesting, brood<br />

rearing and escape cover.<br />

When planting Timothy, seeds should be planted a ½ inch<br />

deep in moist soil, and ¾ inch in dry or coarse textured soils.<br />

It is commonly planted in mixtures with legumes or small<br />

grains. Seeding rates for Timothy depend greatly upon soil<br />

type, moisture, and location. An average seeding rate for<br />

broadcasting is 4-8 lbs/acre, and 2-4 lbs/acre when drill<br />

seeding. When Timothy is seeded in a mixture, apply at a rate<br />

<strong>of</strong> 4-6 lbs/acre. All seeding rates are determined by using Pure<br />

Live Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Timothy is highly responsive to<br />

fertilizers and should be fertilized frequently and in ample<br />

quantities. Pastures and hay fields should be irrigated when<br />

necessary and/or applicable. Irrigation in combination with<br />

fertilization should increase overall yields.<br />

Management<br />

Timothy makes a first rate companion grass for alfalfa,<br />

trefoil, or clover as it is the grass that competes least with<br />

legumes. Over 31 diseases have been reported as affecting<br />

Timothy; however, most <strong>of</strong> these are <strong>of</strong> little concern and can<br />

be controlled. Timothy is susceptible to stem rust disease<br />

which can cause loss <strong>of</strong> vigor and forage quality. Rust-resistant<br />

varieties have been developed to control this disease.<br />

TUFTED HAIRGRASS<br />

Photo: Brennan Veith Low, AK PMC<br />

<strong>Forage</strong> Value<br />

Tufted Hairgrass produces good quality hay for most classes<br />

<strong>of</strong> livestock and wildlife. It also provides ample amounts <strong>of</strong><br />

protein depending on its growing stage. Tufted Hairgrass can<br />

provide good summer pasture forage for livestock. Although<br />

forage value is usually moderate to high, Tufted Hairgrass<br />

consist <strong>of</strong> only 1-3% <strong>of</strong> wild animal diets.<br />

Distribution and Adaptation<br />

Populations <strong>of</strong> Tufted Hairgrass occupy sunny to partially<br />

shaded environments that are moderately moist to seasonally<br />

flooded. The species grows in a wide variety <strong>of</strong> soils; fine to<br />

coarse, mesic to hydric soil types. Tufted Hairgrass is adapted<br />

to a pH range from 4.8 to 7.5. Some populations have extreme<br />

tolerance to heavy metals and high soil acidity. The salinity<br />

tolerance <strong>of</strong> Tufted Hairgrass is generally low, but plants<br />

growing in coastal estuaries may be slightly more salt tolerant.<br />

Tufted Hairgrass is well suited for <strong>Alaska</strong>n environments.<br />

Tufted Hairgrass<br />

Deschampsia cespitosa (L.)<br />

Description<br />

Deschampsia cespitosa (Tufted Hairgrass) is a highly variable,<br />

perennial cool season grass species that grows from 51 to 61<br />

centimeters (20 - 24 inches) tall. Stems are erect, and the<br />

leaves are between 1.5 and 4 mm (.06 - .16 inches) wide, flat or<br />

rolled. The leaves are mostly basal in a dense tuft. Tufted Hairgrass’s<br />

inflorescence is upright to nodding, loosely branched,<br />

open and 10 to 25 cm (4 to 10 inches) long. There are two<br />

florets (flowers) per spikelet. Flowering occurs from May to<br />

September. Tufted Hairgrass seeds mature from late June to<br />

late September, depending on location. Tufted hairgrass produces<br />

approximately 1,360,000 seeds per pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Tufted Hairgrass can be utilized as hay or as<br />

a pasture crop. It is used by cattle, horses, and sheep. The<br />

palatability <strong>of</strong> Tufted Hairgrass is high to moderate for most<br />

livestock.<br />

Wildlife: A large variety <strong>of</strong> wildlife utilizes Tufted Hairgrass<br />

as forage and/or cover. However, most wildlife will not utilize<br />

Tufted Hairgrass as <strong>of</strong>ten as domestic livestock. The species<br />

has moderate to low palatability for elk, bison, bear and<br />

various species <strong>of</strong> waterfowl.<br />

Tufted Hairgrass crowns typically survive all but the most<br />

severe (hottest) fires. One <strong>of</strong> the most widely distributed<br />

grasses on earth, Tufted Hairgrass is found in arctic and<br />

temperate regions. It occurs from sea level to elevations <strong>of</strong> up<br />

to 14,000 ft. Tufted Hairgrass habitat includes coastal terraces,<br />

upper tidal marshes, seasonally wet prairies, moist subalpine<br />

mountain meadows, open forests, and alpine areas above<br />

timberline.<br />

Culture<br />

When planting Tufted Hairgrass, seed should be planted<br />

¼ to ½ inch deep. Seeding rates depend greatly upon soil<br />

type, moisture, and location. An average seeding rate for<br />

broadcasting is 12 lbs/acre and 6 lbs/acre when drill seeding.<br />

All seeding rates are determined by using Pure Live Seed (PLS)<br />

calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied.<br />

Management<br />

Tufted Hairgrass is adapted to northern regions and is well<br />

suited for <strong>Alaska</strong>n environments. One should be aware <strong>of</strong><br />

Tufted hairgrass’s aggressive growth characteristics; it tends<br />

to compete with other grass species. A number <strong>of</strong> diseases<br />

are associated with Tufted Hairgrass, including ergot, stripe<br />

smut, blind seed and other turf diseases. Hairgrass is also<br />

vulnerable to several rusts and leaf spots. Insect pests such as<br />

aphids, billbugs, and leafhoppers can threaten stands <strong>of</strong> Tufted<br />

Hairgrass, and should be monitored.<br />

BARLEY (Cereal)<br />

Wildlife: Barley makes excellent fodder for large ungulate<br />

wildlife, such as moose, elk and bison. It also provides feed<br />

and cover for upland game birds, small mammals, waterfowl<br />

and various song birds.<br />

<strong>Forage</strong> Value<br />

Barley is considered highly palatable and excellent forage for<br />

most classes <strong>of</strong> livestock and wildlife. On average this small<br />

grain produces 12% protein when grown in monoculture. Total<br />

forage protein levels should increase if Barley is intercropped<br />

with Field Pea. Nutritional levels will vary depending on<br />

climate, location, and other agronomic inputs such as<br />

fertilizers, irrigation, and harvest time.<br />

Distribution and Adaptation<br />

Barley seedhead<br />

Barley<br />

Hordeum vulgare (L.)<br />

Description<br />

Photo: <strong>Alaska</strong> PMC<br />

Hordeum vulgare (Barley) is an erect annual bunch grass that<br />

can reach a height <strong>of</strong> 90 centimeters (36 inches) depending<br />

on the variety. This small grain can be intercropped with<br />

legumes, such as Field Pea, to increase forage nutrients and<br />

palatability. Properly managed, legumes provide needed<br />

nitrogen for grasses and protein for livestock. Stems <strong>of</strong> Barley<br />

are hollow, smooth, and glabrous (shiny). Some varieties<br />

are susceptible to lodging. Barley leaves are typically 13 - 19<br />

mm (½ to ¾ <strong>of</strong> an inch) wide and roughly 30 cm (12 inches)<br />

in length. Barley spikelet’s exhibit short or long, narrow, and<br />

scabrous (rough) awns that can be problematic when fed to<br />

livestock. It produces a large spindle shaped seed with high<br />

seedling vigor. Barley plants produce roughly 13,000 seeds per<br />

pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Barley is commonly produced for grain fodder, but<br />

is sometimes fed directly as “green cut” when intercropped<br />

with a legume such as peas. This small cereal grain produces<br />

excellent forage and is highly palatable to all classes <strong>of</strong> livestock.<br />

In addition, Barley produces excellent straw, generally used by<br />

dog mushers for bedding.<br />

Barley can be found growing throughout much <strong>of</strong> the world<br />

including <strong>Alaska</strong>, Canada, and the contiguous United <strong>State</strong>s. It<br />

is adapted to medium textured soils and prefers a pH ranging<br />

from 5.3 to 8.5. Barley is moderately tolerant <strong>of</strong> droughty<br />

and/or wet conditions but does not persist well in shady<br />

environments. It is highly tolerant <strong>of</strong> saline soil conditions.<br />

Culture<br />

Barley grows well in cool moist climates and should be planted<br />

½ to 1½ inches deep. A firm seedbed is essential in providing<br />

good seed to soil contact. This will provide a more reliable<br />

water supply and prevent large air pockets in the soil that are<br />

less than ideal for seedlings to establish.<br />

Barley is typically drill seeded at a rate <strong>of</strong> 70 to 100 lbs/acre<br />

depending upon soil type, moisture, and location. When<br />

seeded with a legume, seeding rates should be reduced<br />

by about half and growth cycles must be synchronized.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before seeding. Irrigation in combination with fertilization<br />

should increase field productivity.<br />

Management<br />

Barley is an excellent grain and forage crop if properly<br />

managed. Barley is well adapted to <strong>Alaska</strong>’s long day length<br />

and short growing season. Several barley cultivars have been<br />

specifically developed to survive <strong>Alaska</strong>’s harsh climate, while<br />

producing higher nutritional grain and forage values. The<br />

cultivar ‘Weal’ is an awnless Barley that was developed as a<br />

dual purpose grain and/or forage.<br />

65


Barley requires adequate moisture and responds well to<br />

nitrogen fertilizer. When planting Barley with legume species<br />

nitrogen should not be over applied due to the adverse affects<br />

it can have on nitrogen fixing plants. Lodging can also be<br />

problematic with some Barley cultivars; one should conduct<br />

ample research about their selected cultivar before planting.<br />

Currently, producers are evaluating the costs and benefits <strong>of</strong><br />

irrigation on the production <strong>of</strong> Barley and other cereal grains<br />

throughout <strong>Alaska</strong>.<br />

Barley is susceptible to powdery mildew (Blumeria graminis),<br />

leaf scald (Rhynchosporium secalis), and barley rust, (Puccinia<br />

hordei), covered smut (Ustilago hordei), loose smut (Ustilago<br />

nuda) and ergot (Claviceps purpurea). To date, these Barley<br />

diseases have not been found in <strong>Alaska</strong>. Therefore, cultivars<br />

developed for <strong>Alaska</strong> do not have a strong resistance to<br />

disease. Before planting, many farmers treat seed to prevent<br />

ergot and smut. Managers should also rotate crops and select<br />

disease free seed when applicable.<br />

COMMON OAT (Cereal)<br />

Uses<br />

Livestock: Oats are commonly used as a hay and silage<br />

crop, but can also be used for pasture. This small cereal grain<br />

makes excellent forage and is highly palatable to all classes <strong>of</strong><br />

livestock. Early growth oat plants can be fed as “green cut”<br />

forage for livestock. In addition, oat straw makes excellent<br />

roughage.<br />

Wildlife: Oats have excellent forage value for a large variety<br />

<strong>of</strong> wildlife such as bears, elk, bison and moose. They are also<br />

used for food and cover by upland game birds, waterfowl,<br />

small mammals and various song birds.<br />

<strong>Forage</strong> Value<br />

Oats are highly palatable and excellent forage to all classes<br />

<strong>of</strong> livestock and wildlife. The species produces moderate/<br />

high protein and carbohydrate levels. Oats can be fed as hay,<br />

silage, green cut, grain, and/or eaten directly on the pasture.<br />

Nutritional levels will vary depending upon the selected<br />

form that oats are fed as well as how other agronomic inputs<br />

(fertilizer, irrigation, harvest time) are managed and applied.<br />

Oat hay generally contains 10 to 15 % protein and is typically<br />

intercropped with a legume such as peas for added nutrition.<br />

Common Oat, Avena sativa<br />

Common Oat<br />

Avena sativa (L.)<br />

Description<br />

Avena sativa, Common Oat is an erect growing annual bunch<br />

grass that produces a fibrous root system. This small grain<br />

can attain heights greater than 60 centimeters (24 inches),<br />

depending on variety. Oats are generally intercropped with<br />

various legumes such as clovers and/or field peas to increase<br />

forage nutrient levels. This also allows some legumes to use<br />

their tendrils to climb the stalks <strong>of</strong> standing grass. Leaves are<br />

non-auriculate and medium to dark green in color. Avena<br />

sativa produces a large, lance shaped seed with high seedling<br />

vigor. Oat plants typically produce 20,000 seeds per pound <strong>of</strong><br />

seed, depending upon the variety.<br />

Distribution and Adaptation<br />

Oats can be found growing throughout much <strong>of</strong> the world<br />

including <strong>Alaska</strong>, Canada, and the contiguous United <strong>State</strong>s.<br />

It is adapted to fine to coarse textured soils, and prefers a<br />

soil pH between 5.3 - 8.5. Oats are moderately tolerant <strong>of</strong><br />

saline soils and droughty conditions. However, this small grain<br />

prefers adequate moisture and will not tolerate shady growing<br />

environments.<br />

Culture<br />

Oats are best adapted to cool moist climates and should be<br />

planted 1½ to 2 inches deep. A firm seed bed allowing good<br />

seed to soil contact is essential. Soil samples should be collected<br />

and analyzed before seeding. Oats are generally drill seeded at<br />

a rate <strong>of</strong> 50 to 90 lbs/acre. Seeded with a legume, seeding rates<br />

should be reduced by about half, and growth cycles should be<br />

synchronized. Appropriate fertilizer ratios depend upon soil<br />

type, chemistry, and location. Irrigation in combination with<br />

fertilization should increase field productivity.<br />

67


Management<br />

Oats make an excellent forage crop when properly managed.<br />

This small grain is well adapted to <strong>Alaska</strong>’s long days and short<br />

growing season in the summer. Oats are better adapted to<br />

lower pH soils than Barley or Wheat. Oat will complement<br />

various legumes when intercropped, and the species makes<br />

a high protein and carbohydrate fodder. When planting oats<br />

with a legume species, nitrogen should not be over applied<br />

due to the adverse affects it can have on nitrogen fixing plants.<br />

Common Oat (Avena sativa L.) is the species most used in<br />

in <strong>Alaska</strong>, although other species such as Black Oat (Avena<br />

strigosa L.), Red Oat (Avena byzantina C. Koch), and Hulless<br />

Oat (Avena nuda L.) are also successfully grown throughout<br />

the state. Oat straw does not contain long awns, making it<br />

more desirable than barley straw for use as animal bedding.<br />

Some oat varieties have difficulty with lodging - conduct<br />

research prior to planting.<br />

Oat diseases have not been a significant problem in<br />

<strong>Alaska</strong>. Fungi such as scald (Rhynchospoium secalis), stripe<br />

(Pyrenophora graminea), net blotch (Pyrenophora teres), spot<br />

blotch (Cochliobolus sativus) and smuts (Ustilago spp.) have<br />

been known to occur. To help prevent disease outbreaks,<br />

managers should rotate crops in the field periodically and be<br />

prudent about selecting disease free seed.<br />

ALFALFA<br />

<strong>Forage</strong> Value<br />

Alfalfa produces large amounts <strong>of</strong> protein and is excellent<br />

quality forage for all classes <strong>of</strong> livestock and wildlife. This<br />

legume has the highest feed value <strong>of</strong> all commonly grown hay<br />

crops. Alfalfa is one <strong>of</strong> the most important forage plants in<br />

production agriculture; sometimes called the “Queen <strong>of</strong> the<br />

<strong>Forage</strong>s”. It is high in mineral content and possesses excellent<br />

nutritional value, containing at least 10 different vitamins.<br />

Distribution and Adaptation<br />

Alfalfa<br />

Medicago sativa (L.)<br />

Description<br />

A mature stand <strong>of</strong> Alfalfa<br />

Medicago sativa, Alfalfa is a long lived perennial legume. It<br />

grows erect culms, 76 - 91 centimeters (30 to 36 inches) in<br />

height, branching from a single base. Leaves alternate on the<br />

stem and are pinnately trifoliolate, while individual leaflets are<br />

obovate (ovalish) or lancolate (lance shaped). Alfalfa produces<br />

numerous flowers that are purplish to yellow and borne in loose<br />

racemes or clusters. Alfalfa grows a series <strong>of</strong> lateral roots, with<br />

a distinct tap root that may penetrate 6 to 9 meters (20 to 30<br />

feet) below soil surface. This legume produces a small kidney<br />

shaped seed. Alfalfa produces 190,000 to 220,000 seeds per<br />

pound <strong>of</strong> seed, depending upon variety. Seedling vigor can be<br />

low to moderate, also depending upon the selected variety.<br />

Alfalfa is adapted to a variety <strong>of</strong> climatic and soil conditions,<br />

and can be found growing throughout the United <strong>State</strong>s<br />

and parts <strong>of</strong> Canada. Varieties such as ‘Denali’ have been<br />

hybridized to better withstand extreme <strong>Alaska</strong>n climates.<br />

Generally, Alfalfa prefers deep well drained medium textured<br />

soils, with a pH <strong>of</strong> 6 to 8.5. It is highly drought tolerant and<br />

can withstand saline soils. Alfalfa will not tolerate sites with<br />

frequent overflow or high water tables.<br />

Culture<br />

Alfalfa should be planted no deeper than a ¼ inch on fine<br />

textured soils and ½ inch deep on coarse soils. It should be drill<br />

seeded on a firm seed bed. Cultipacking the soil before and<br />

after planting Alfalfa is normally recommended. Seeding rates<br />

depend greatly upon soil type, moisture, and location. Note<br />

that Alfalfa can have trouble over-wintering and competing<br />

with perennial grasses.<br />

An average seeding rate when broadcasting Alfalfa is 10 lbs/<br />

acre and 5 lbs/acre when drill seeding. All seeding rates are<br />

determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B. Appropriate fertilizer ratios depend<br />

upon soil type, chemistry and location. Research in <strong>Alaska</strong> has<br />

shown that the application <strong>of</strong> fertilizer produces no significant<br />

yield change. If applying fertilizer, collect and analyze soil<br />

samples first. Pastures and hay fields should be irrigated when<br />

necessary and/or applicable.<br />

Uses<br />

Livestock: Alfalfa is typically used for haying, silage, and<br />

pastures land. However, it can also be fed as haylage, wafers,<br />

pellets or dried meal. It is highly palatable to all classes <strong>of</strong><br />

livestock, but caution is advised when feeding Alfalfa due to its<br />

high bloat hazard.<br />

Wildlife: Alfalfa is highly palatable to a variety <strong>of</strong> large wildlife,<br />

such as deer, elk and bison. It is utilized as food and cover by<br />

small mammals, waterfowl and upland game birds. Canada<br />

geese, sandhill cranes, rough grouse and mallard ducks can be<br />

found utilizing Alfalfa.<br />

Management<br />

Alfalfa makes an excellent pasture, hay or silage forage.<br />

Although this crop is usually harvested 2 years after planting,<br />

one should be aware that most varieties will not overwinter<br />

throughout <strong>Alaska</strong>. This can be attributed to several<br />

environmental factors such as acid soils, nutrient deprived<br />

soils, cold stress and damage to the plants root system. There<br />

are several varieties <strong>of</strong> Alfalfa that have been developed or<br />

hybridized to combat these factors.<br />

Alfalfa will tolerate moderate pasture grazing, but stands will<br />

weaken if over grazed or grazed too <strong>of</strong>ten. When applicable,<br />

Alfalfa can be grown with a perennial grass species, such as<br />

Alsike Clover, Trifolium hybridum<br />

Alsike Clover<br />

Trifolium hybridum (L.)<br />

Description<br />

Trifolium hybridum, Alsike Clover is a short lived perennial<br />

and/or biennial legume that can reach 45 to 60 centimeters<br />

(18 to 24 inches) tall. It grows decumbent to erect vertically<br />

ridged culms. Leaves are palmately trifoliate with long<br />

petioles on the lower leaves and smaller or reduced petioles<br />

on the upper leaves. Individual leaflets are obovate (ovalish)<br />

or elliptic (narrow oval) with narrow tipped stipules. Alsike<br />

produces numerous flowers that are pink, red, and/or white<br />

and borne in leaf axils at the end <strong>of</strong> stems.<br />

Alsike is similar to several other introduced Trifolium<br />

species that occur throughout <strong>Alaska</strong>, such as Golden Clover<br />

(Trifolium aureum), Lupine Clover (T. lupinaster), Red Clover<br />

(T. pratense), White Clover (T. repens), and Field Clover (T.<br />

campestre). This legume produces a small round shaped seed,<br />

and most varieties produce roughly 650,000 seeds per pound<br />

<strong>of</strong> seed. Seedling vigor is low to moderate, depending upon<br />

the selected variety.<br />

Uses<br />

Livestock: Alsike is used for hay and pasture grazing. It is<br />

highly palatable to all classes <strong>of</strong> livestock. Caution should be<br />

taken when feeding Alsike to horses, as it can be toxic under<br />

some conditions. Also be cautious when feeding Alsike in large<br />

quantities, due to its high bloat hazard.<br />

Wildlife: Alsike is highly palatable to a variety <strong>of</strong> large wildlife,<br />

such as deer, elk and bison. It is utilized as food and cover<br />

by small mammals, waterfowl and upland game birds. Canada<br />

geese, sandhill cranes, rough grouse and mallard ducks utilize<br />

Alsike Clover.<br />

<strong>Forage</strong> Value<br />

Alsike is capable <strong>of</strong> producing large amounts <strong>of</strong> protein<br />

and is excellent quality forage for most classes <strong>of</strong> livestock<br />

and wildlife. Although it is generally out-produced by other<br />

legumes, it is highly palatable and produces a high relative feed<br />

value (RFV). It provides adequate mineral and vitamin content<br />

and is commonly grown with other grass species, including<br />

Timothy (Phleum pratense). As with most legumes, caution<br />

should be taken when feeding alsike due to the possibility <strong>of</strong><br />

bloat.<br />

Distribution and Adaptation<br />

Alsike is adapted to a variety <strong>of</strong> climatic and soil conditions. It<br />

is found growing throughout the entire United <strong>State</strong>s and parts<br />

<strong>of</strong> Canada. Alsike can tolerate fine to medium textured soils<br />

with a pH ranging from 5.6 to 7.5. Although it can persist in<br />

wetter and more acidic soils better than other clover species,<br />

Alsike will not tolerate shady, droughty or saline environments.<br />

Culture<br />

Alsike should be planted ¼ to ½ inches deep in a firm seed bed,<br />

preferably in silty loams and/or finer textured soils. Seeding<br />

rates depend greatly upon soil type, moisture, and location.<br />

An average seeding rate when broadcast seeding Alsike is 6<br />

lbs/acre and 2-4 lbs/acre when drill seeding. Seed should be<br />

inoculated prior to planting with appropriate rhizobium to<br />

assist plant establishment. Seeding rates are determined using<br />

Pure Live Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before field seeding. High rates <strong>of</strong> nitrogen application can<br />

damage or destroy stands <strong>of</strong> Alsike, and caution should be<br />

taken when applying fertilizer. Pastures and hay fields should<br />

be irrigated when necessary and/or applicable.<br />

Management<br />

Alsike makes an excellent pasture or hay forage. This legume<br />

is adapted to acidic, poorly drained, and/or moderate to low<br />

nutrient soils. Alsike can be difficult to control for the first<br />

several years <strong>of</strong> production, due to its aggressive nature and<br />

tendency to compete with other plants. It is highly recommend<br />

that Alsike be seeded in combination with a grass species<br />

to keep it from dominating a forage stand. Typically, Alsike<br />

Clover is seeded with a grass species such as Timothy (Phleum<br />

pratense) to reduce the risk <strong>of</strong> bloating and toxic affects when<br />

feeding to horses. Seeding with a grass species will also help<br />

Alsike stand upright making for an easier harvest.<br />

This legume will readily move into disturbed areas, and one<br />

should be mindful when selecting this species as a forage<br />

choice. Alsike requires a minimum <strong>of</strong> 110 frost-free days for<br />

successful reproduction and will continue to bloom throughout<br />

the entire growing season. Alsike responds well to irrigation,<br />

moderate grazing pressure, and commercial fertilizers. Little<br />

research has been conducted concerning potential pests that<br />

may affect Alsike in <strong>Alaska</strong>.<br />

FIELD PEA<br />

Field Pea<br />

Pisum sativum (L.)<br />

Description<br />

Mature Field Pea plant<br />

Pisum sativum, Field Pea is an annual legume that is prostrate<br />

(flat growing) by nature. When intercropped with a grass or<br />

small grain, however, the legume can reach a height <strong>of</strong> 60<br />

to 120 centimeters (24 to 48 inches), depending on variety.<br />

Intercropping allows Field Pea to wrap itself around the<br />

secondary crop allowing it to grow upward. A single leaf<br />

consists <strong>of</strong> one to three pairs <strong>of</strong> leaflets that are terminated<br />

with a branched tendril (used for climbing). Field Pea leaves<br />

are usually pale green with white blotches. This legume has a<br />

large round shaped seed and generally produces 1,600 to 5,000<br />

seeds per pound <strong>of</strong> seed, depending upon variety. Seedling<br />

vigor is low to moderate and seeds should be inoculated with<br />

proper bacterium when applicable.<br />

Uses<br />

Livestock: Field Pea is used for pasture, hay, silage and/or<br />

green cut. It is excellent forage and is highly palatable to all<br />

classes <strong>of</strong> livestock. This legume is <strong>of</strong>ten intercropped with<br />

annual grasses or oats to obtain optimal nutrient and mineral<br />

requirements <strong>of</strong> livestock.<br />

Wildlife: Field Pea is highly palatable to a variety <strong>of</strong> wildlife<br />

such as deer, elk, moose and bison. It is also utilized as food<br />

and cover for small mammals, waterfowl and upland game<br />

birds.<br />

<strong>Forage</strong> Value<br />

Field Pea is highly palatable to all classes <strong>of</strong> livestock and<br />

wildlife. It produces 20 to 25 percent protein on average and<br />

contains high levels <strong>of</strong> carbohydrates. This legume generally<br />

produces greater than 85% total digestible nutrients, with low<br />

fiber content. Intercropped with annual grasses or small grains,<br />

Field Pea can increase combined protein levels two to four<br />

times higher than with grass or small grains in monoculture.<br />

Field Pea has a moderate bloating factor, compared to other<br />

legumes, and should be fed with a grass or small grain forage<br />

to reduce the risk <strong>of</strong> bloating.<br />

Distribution and Adaptation<br />

Field Pea prefers cool, moist conditions and can be found<br />

growing throughout parts <strong>of</strong> <strong>Alaska</strong>, Canada, Greenland and<br />

the contiguous United <strong>State</strong>s. Field Pea is adapted to a variety<br />

<strong>of</strong> soil textures such as sandy loams, silts to heavy clays, and<br />

requires adequate drainage with a pH between 5.2 and 6.5.<br />

This legume cannot tolerate saline or droughty conditions.<br />

Culture<br />

Field Pea should be planted 1 to 3 inches deep in a moist firm<br />

seedbed. This promotes good seed to soil contact. Seeding<br />

rates depend greatly upon soil type, moisture, and location.<br />

Field Pea should be drill seeded when applicable, and is<br />

generally seeded at a rate <strong>of</strong> 190 lbs/acre, or 7 to 9 plants per<br />

square foot. This legume does not compete well with other<br />

species. A heavier seeding rate allows field pea to better<br />

compete with weeds.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before seeding. Field Pea requires phosphorus and potassium<br />

in relatively large amounts. Nitrogen is also necessary if<br />

planting in nutrient deprived soils. Over application <strong>of</strong><br />

nitrogen fertilizer can have adverse affects, however, reducing<br />

the potential <strong>of</strong> nitrogen fixation by plants. Fields should<br />

be irrigated when necessary. Irrigation in combination with<br />

fertilization can increase field productivity.<br />

Management<br />

Field Pea makes an excellent forage crop if properly managed.<br />

It can provide needed nitrogen for grasses and protein for<br />

livestock. Field Pea is not typically used for grazing, but rather<br />

it is used for silage or green chop. There are several pests that<br />

can affect Field Pea production, such as Mycosphaerella and<br />

Ascochyta. These fungi can result in poor plant performance<br />

and death if not managed. A preferred management tactic is<br />

to rotate field pea stands for several growing seasons, thus not<br />

allowing the fungus spores to persist. Fungi can survive for<br />

several years on Field Pea stubble and seed. Insects such as<br />

aphids, lygus bugs and grass hoppers can also affect Field Pea<br />

performance, though they are not usually a problem.<br />

RED CLOVER<br />

<strong>Forage</strong> Value<br />

Red Clover can produce high yields and is excellent forage for<br />

all classes <strong>of</strong> livestock and wildlife. Depending on season <strong>of</strong><br />

harvest, protein content <strong>of</strong> 15-25% is common. Digestibility<br />

and relative feed value start high, but decline with plant<br />

maturity. Caution should be taken when feeding Trifolium<br />

pratense to animals due to the possibility <strong>of</strong> bloat.<br />

Red Clover<br />

Trifolium pratense (L.)<br />

Description<br />

Red Clover, Trifolium pratense<br />

Trifolium pratense, Red Clover is a short lived perennial or<br />

biennial legume. It grows erect to decumbent culms that are<br />

hairy and hollow. Each leaf consists <strong>of</strong> a slender stalk which is<br />

petiolated and bearing 3 leaflets, which are oblong to obovate<br />

(ovalish shape). Red Clover produces numerous flowers borne<br />

in compact clusters that are reddish to pink in color. There<br />

are two types <strong>of</strong> Red Clover that are commonly referred to as<br />

Medium and Mammoth. Medium Red Clover ranges in height<br />

from 45 - 60 centimeters (18 to 24 inches), while Mammoth<br />

Red Clover reaches an average height <strong>of</strong> 75 centimeters (30<br />

inches). Red Clover grows a series <strong>of</strong> lateral roots with a<br />

tap root that is extensively branched. This legume produces<br />

a small kidney shaped seed that is yellow to deep violet in<br />

color. Red clover has high seedling vigor and produces roughly<br />

270,000 seeds per pound <strong>of</strong> seed.<br />

Uses<br />

Livestock: Red Clover is typically used for hay, pastureland,<br />

and/or silage. It produces high quality forage that is palatable<br />

to all classes <strong>of</strong> livestock.<br />

Wildlife: Red Clover is highly palatable to large grazing and<br />

browsing animals such as deer, elk and bison. It is also utilized<br />

as food and cover by small mammals, waterfowl, and upland<br />

game birds.<br />

Red Clover is adapted to a variety <strong>of</strong> soils types but grows<br />

best in well drained loamy soils. It can be found growing<br />

throughout the United <strong>State</strong>s and Canada. Red Clover prefers<br />

a pH <strong>of</strong> 5.5 to 7.5 and has low drought tolerance. This legume<br />

can tolerate high moisture environments and has a moderate<br />

to low shade tolerance.<br />

Culture<br />

Red Clover should be planted at ¼ to ½ inch deep in well<br />

drained loamy to silt loam soils that have a high water holding<br />

capacity. It should be inoculated with the appropriate rhizobium<br />

innoculant, as this will help with plant establishment and<br />

seedling vigor. When seeded alone in pure stands, Red Clover<br />

should be drill seeded at a rate <strong>of</strong> 6-12 lbs/acre and 20-25 lbs/<br />

acre when broadcast seeding. Red Clover can also be seeded<br />

in mixtures with small grains or grasses like Barley (Hordeum<br />

vulgare), Timothy (Phleum pratense), and Smooth Brome<br />

(Bromus inermis). Standard seeding rates when seeded in a<br />

mix is 4-8 lbs/acre. All seeding rates are determined by using<br />

Pure Live Seed (PLS) calculations, as described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before fertilizer is applied. Phosphorus is used in large<br />

quantities by Red Clover, which is a limiting factor on most soils.<br />

Pastures and hay fields should be irrigated when necessary<br />

and/or applicable. Irrigation in combination with fertilization<br />

should increase overall yields.<br />

Management<br />

Red Clover makes an excellent pasture, hay, or silage forage.<br />

It should be harvested ¼ to ½ in bloom during the first cutting.<br />

Successive grazing or a second cutting should occur when the<br />

legume is ¼ <strong>of</strong> the way into bloom stage, and at least 2 inches<br />

<strong>of</strong> growth should remain after harvest. Red Clover responds<br />

well to fertilizers and should be supplied with ample amounts<br />

<strong>of</strong> phosphorus and/or potash. Red Clover also responds well<br />

to irrigation when planted in moderate to well drained soils.<br />

When growing Red Clover, one should monitor for powdery<br />

mildew in areas <strong>of</strong> high humidity and/or rainfall. Resistant<br />

cultivars have been developed to reduce the occurrence <strong>of</strong><br />

these pests.<br />

WHITE CLOVER<br />

White Clover in bloom<br />

White Clover<br />

Trifolium repens (L.)<br />

Description<br />

Trifolium repens, White Clover is a moderate lived perennial<br />

legume that can attain heights <strong>of</strong> 15 - 30 centimeters (6 to 12<br />

inches), depending upon variety. It has a prostrate (flat) growth<br />

habit, spreading laterally by stolons. Leaves are composed <strong>of</strong><br />

three leaflets that sometimes display a watermark or crescent.<br />

Leaves and roots are borne along the stolon at each node.<br />

Inflorescence (seed-head) consists <strong>of</strong> 40 to 100 florets that are<br />

borne along long slender stalks. Florets are usually white, but<br />

sometimes display a pink hue. White Clover has a shallow root<br />

system with a primary tap root that seldom roots deeper than<br />

60 centimeters (24 inches). This legume grows a small heart<br />

shaped seed, and produces roughly 700,000 seeds per pound<br />

<strong>of</strong> seed. Seedling vigor is low to moderate depending upon<br />

the selected variety.<br />

Uses<br />

Livestock: White Clover can be used for pasture, hay or silage<br />

production. It is highly palatable to all classes <strong>of</strong> livestock and<br />

has a low potential <strong>of</strong> bloating.<br />

Wildlife: White Clover is highly palatable to a variety <strong>of</strong> large<br />

wildlife, such as deer, elk, moose and bison. It is also utilized<br />

as food and cover by small mammals, waterfowl and upland<br />

game birds.<br />

<strong>Forage</strong> Value<br />

White Clover is highly palatable to all classes <strong>of</strong> livestock<br />

and wildlife. It produces ample amounts <strong>of</strong> protein with<br />

consistently high mineral content, compared to other clover<br />

species. This legume is highly digestible and generally<br />

produces a higher percentage <strong>of</strong> amino acids than Alfalfa and/<br />

or Red Clover. When nutrients are available, White Clover can<br />

concentrate Na, P, Cl, and/or Mo, delivering these nutrients to<br />

grazing animals. The risk <strong>of</strong> bloating is generally moderate to<br />

low and is greatly reduced when White Clover is grown with<br />

grass species.<br />

Distribution and Adaptation<br />

White Clover is adapted to moist and/or wet conditions and<br />

can be found growing throughout the United <strong>State</strong>s, Canada,<br />

and some portions <strong>of</strong> <strong>Alaska</strong>. It prefers fine texture soils such<br />

as silts and clays, containing moderate to high nutrient levels.<br />

White Clover will persist in soils with a pH ranging from 5.2-<br />

8.0. It will not tolerate or sustain in shady, droughty, saline, or<br />

nutrient deprived environments.<br />

Culture<br />

White Clover should be planted ¼ to ½ inch deep in a firm<br />

seed bed with well drained silty or clay loam soils. Seeding<br />

rates depend greatly upon soil type, moisture, and location.<br />

It is highly recommended that White Clover be drill seeded<br />

to ensure good seed to soil contact. An average seeding rate<br />

when drill seeding White Clover is 2-4 lbs/acre. This seeding<br />

rate applies to almost all situations and can be used when<br />

planting White Clover with a grass species. A widely accepted<br />

ratio <strong>of</strong> 2:1 is an ideal balance <strong>of</strong> grass to clover, using the<br />

above recommended clover drilling rate. All seeding rates<br />

are determined by using Pure Live Seed (PLS) calculations, as<br />

described in Appendix B.<br />

Appropriate fertilizer ratios depend upon soil type, chemistry,<br />

and location. Soil samples should be collected and analyzed<br />

before field seeding. High application rates <strong>of</strong> nitrogen can<br />

damage or destroy stands <strong>of</strong> White Clover and caution<br />

should be taken when applying fertilizer. Pastures and hay<br />

fields should be irrigated when necessary and/or applicable.<br />

Irrigation in combination with fertilization should increase<br />

field productivity.<br />

Management<br />

White Clover makes an excellent pasture forage, but is<br />

generally not used for hay or silage production unless large<br />

and/or tall cultivars are selected and grown. The cultivar<br />

‘Ladino’ is a large and tall growing variety <strong>of</strong> white clover that<br />

is commonly used for hay, silage, and green chop production.<br />

White Clover will respond well to irrigation, moderate grazing<br />

pressure, and commercial fertilizers. This legume usually<br />

displays adverse affects when nitrogen fertilizers are supplied<br />

in excess. Liming may be necessary to achieve the optimal pH<br />

for white clover growth.<br />

White Clover is typically grown with other forage grasses.<br />

This is generally implemented in order for grasses to take<br />

advantage <strong>of</strong> the nitrogen fixating ability <strong>of</strong> White Clover, and<br />

to lower the potential <strong>of</strong> bloating by adding dry matter to the<br />

feed mix. White Clover can be susceptible to a number <strong>of</strong><br />

root and leaf diseases as well as insect pests. Most <strong>of</strong> these<br />

potential problems exist in mid to lower latitudes.<br />

Detailed measurements <strong>of</strong> nutrient availability at various plant growth stages were taken during this study.<br />

Introduction<br />

<strong>Forage</strong> production in <strong>Alaska</strong> presents unique challenges, due to the short growing<br />

season (100-118 days) and harsh environments encountered throughout diverse regions<br />

<strong>of</strong> the state. Spring planting is optimal, as planted species are able to utilize<br />

available moisture from winter snowmelt and take advantage <strong>of</strong> the warmer temperatures<br />

and longer days <strong>of</strong> summer. Average summer temperatures in <strong>Alaska</strong> range<br />

from 51 - 61 ̊F, with an 18 to 24 hour photo period in June.<br />

Though these climatic factors present some challenges, forage production numbers<br />

are stable. The mean per ton cost varies largely in <strong>Alaska</strong>, from $225/ton - $750/ton,<br />

considerably higher than the $90 per ton common in the lower 48. The high price<br />

variability can be attributed to high production costs, a shortage <strong>of</strong> available hay and<br />

uncontrollable climate variables. To adapt to and overcome <strong>Alaska</strong>’s climate and geography,<br />

managers should choose forage species with high nutritional value. This will<br />

enable an animal’s nutrient intake levels to be met while minimizing the expense <strong>of</strong><br />

nutritional supplements.<br />

82


Purpose<br />

The goal <strong>of</strong> this study was to determine nutrient<br />

content <strong>of</strong> forage species within each distinct plant<br />

growth stage. Five growth stages were examined<br />

for grass, legume, and cereal crop species - Vegetative,<br />

Pre-boot, Boot, Anthesis (flowering) and Caryopsis<br />

(ripening). Samples <strong>of</strong> vegetative matter were<br />

taken at each stage and sent to a lab for nutrient<br />

analysis. Data extrapolated from testing can be used<br />

by producers and consumers as a means <strong>of</strong> choosing<br />

forage species based on the needs <strong>of</strong> livestock and/<br />

or wildlife.<br />

An additional intent <strong>of</strong> this study was to look at the<br />

nutritional content <strong>of</strong> native and non-native plant<br />

species, and determine if any non-native species<br />

have sufficiently high nutritional value to warrant<br />

inclusion in forage plantings in <strong>Alaska</strong>. Timothy and<br />

Brome are two examples <strong>of</strong> non-native species with<br />

high nutritional value.<br />

Methods & Procedures<br />

This effort was conducted at <strong>Alaska</strong> <strong>Plant</strong> <strong>Materials</strong><br />

<strong>Center</strong> in Palmer, <strong>Alaska</strong> during the 2011 growing<br />

season. Fields were well established and fairly free<br />

<strong>of</strong> weeds. <strong>Plant</strong> species were evaluated and growth<br />

stages were monitored daily. Each species collection<br />

was accompanied by field observations as noted by<br />

the sample collector. Standardized collection procedures<br />

were followed.<br />

Growth <strong>State</strong> Indicators<br />

1. Vegetative: Leaf growth and development; no<br />

stems<br />

2. Pre-boot: Stem elongation or “jointing”; stem<br />

or culm development occurs<br />

3. Boot: The seedhead (inflorescence) emerges<br />

from the tiller<br />

4. Anthesis (flowering): Pollen starts to shed from<br />

the anthers<br />

5. Ripening: This stage begins with the development<br />

<strong>of</strong> the caryopsis (seed) and ceases when<br />

they are ripe. Also denotes the end <strong>of</strong> the growing<br />

season; leaves start to change color.<br />

Species Collection<br />

1. A handful <strong>of</strong> grass was clipped with scissors, leaving<br />

about 2-3 inches <strong>of</strong> stubble above ground.<br />

Five samples were collected for each species.<br />

2. Each sample was cut into sections <strong>of</strong> approximately<br />

8 inches in length, placed into a five gallon<br />

bucket and then mixed together so representative<br />

samples could be taken. Any decadent<br />

(previous year’s) growth was removed so that<br />

only the current season’s growth was analyzed.<br />

3. Approximately 200 grams <strong>of</strong> grass was removed<br />

from the five gallon bucket and put into a ½ gallon<br />

bag. Each bag was labeled with date, species<br />

name, and growth stage.<br />

4. Samples collected were delivered the same day<br />

to the University <strong>of</strong> <strong>Alaska</strong> Fairbanks Experiment<br />

Farm for testing.<br />

Lab Analysis<br />

Samples were collected from well established fields<br />

near the <strong>Plant</strong> <strong>Materials</strong> <strong>Center</strong> in Palmer, <strong>Alaska</strong>.<br />

The samples were gathered during the following<br />

growth stages; Vegetative, Pre-boot, Boot, Anthesis<br />

(flowering) and Ripening. The rationale <strong>of</strong> collecting<br />

samples in these growth stages was to determine<br />

the gain and loss <strong>of</strong> nutrients throughout a typical<br />

graminoid life cycle.<br />

Samples submitted for analysis were tested for<br />

crude protein (CP) , minerals, acid detergent fiber<br />

(ADF), neutral detergent fiber (NDF), total digestible<br />

nutrients (TDN) and various other constituents. ADF<br />

and NDF are used to measure the portion <strong>of</strong> indigestible<br />

material within the sample, which inversely correlates<br />

to nutrient content.<br />

The relative feed value (RFV) is an estimate <strong>of</strong> forage<br />

quality and is calculated from ADF and NDF percentages.<br />

The RFV grading system assumes that full<br />

bloom alfalfa has an RFV <strong>of</strong> 100; this legume is typically<br />

used as a baseline reference for grading forage.<br />

The RFV for each grass species within this study was<br />

calculated for all five growth stages. Results can be<br />

compared to the ranges given in the table below,<br />

developed by the American <strong>Forage</strong> and Grassland<br />

Council as a guideline for measuring forage quality.<br />

Report <strong>of</strong> Findings<br />

As expected, all grass species showed higher crude<br />

protein values during the vegetative and pre-boot<br />

(early growth cycle) stages. Decline in protein levels<br />

became evident after boot stage, though indigestible<br />

nutrients (fiber) began to increase. Other essential<br />

minerals like phosphorus (P), potassium (K), and<br />

Calcium (Ca) were measured in higher levels during<br />

the early growth stages and began to drop as plant<br />

species neared maturity. Acid and Neutral detergent<br />

fiber percentages increased steadily throughout the<br />

plant’s life cycle, lowering the relative feed value and<br />

total digestible nutrients percentage <strong>of</strong> each forage<br />

species.<br />

This nutrient assessment can assist growers in determining<br />

the best possible time to harvest forage<br />

based on the needs <strong>of</strong> their livestock and/or wildlife.<br />

If a grower seeks high quality and/or high nutrient<br />

forage, grasses should be harvested during an earlier<br />

growth such as the boot stage. When high production<br />

yield is the goal, grasses should be harvested<br />

later, during the anthesis and/or flowering stage.<br />

Scheduling the harvest based on stages <strong>of</strong> plant development<br />

can be a reliable way to obtain a desired<br />

yield and/or quality forage from year to year.<br />

Graph Interpretation<br />

When interpreting data in the Nutrient Study, one<br />

should be aware <strong>of</strong> several characteristics associated<br />

with the following graphs. In general, Relative<br />

Feed Value (RFV), Crude Protein (CP) and Total<br />

Digestible Nutrient (TDN) values will decrease with<br />

time as a plant matures through the growing season.<br />

Contrarily, Neutral Detergent Fiber (NDF) and Acid<br />

Detergent Fiber (ADF) values should typically increase<br />

with time and plant maturity. Pronounced increases<br />

or decreases (spikes) within the graphs can<br />

be attributed to the variability in randomly selected<br />

forage samples.<br />

All data within the graphs <strong>of</strong> this study are displayed,<br />

so the reader may compare nutrient values<br />

and trends with other grass species. While not presented<br />

in graph form, values for phosphorus (P), potassium<br />

(K), calcium (Ca), in-vitro dry matter digestibility<br />

(IVDMD), metabolized energy, net energy, and<br />

dry matter (DM) are listed in a table for each grass<br />

species.<br />

Appendix B: Seed Specifications / Certification<br />

Seed Specifications<br />

Quality seed is critical to success.<br />

Specifying “certified” seed<br />

assures quality because the seed<br />

must meet certain standards for<br />

germination and purity; certification<br />

also provides some assurance<br />

<strong>of</strong> genetic quality.<br />

Some native seed species are<br />

not available as certified seed.<br />

Seed quality can still be ascertained by examining percent<br />

germination and percent purity; information that will be<br />

clearly labeled for any seed sold in <strong>Alaska</strong>. This labeling is<br />

required by 11 AAC, chapter 34: Seed Regulations.<br />

The true cost <strong>of</strong> seed can be determined by the Pure<br />

Live Seed calculation. To calculate Pure Live Seed (PLS),<br />

use the equation:<br />

The true price <strong>of</strong> seed, then, can be determined<br />

using the equation:<br />

These calculations can increase the accuracy <strong>of</strong> bid comparisons.<br />

PLS price is a good method <strong>of</strong> comparing different<br />

seed lots at time <strong>of</strong> purchase. All seed sold or used in<br />

the state <strong>of</strong> <strong>Alaska</strong> must also be<br />

free <strong>of</strong> noxious weeds, under 11<br />

AAC 34.075. This is noted on seed<br />

tags, along with germination and<br />

purity.<br />

Seeding Rates<br />

When determining seeding<br />

rates, divide the desired seeding<br />

rate by the percent germination<br />

<strong>of</strong> the seed being used. For example,<br />

to achieve a 10 lbs/ acre seeding rate with seed having<br />

an 80% PLS (determined using the equation above), 10<br />

lbs / .80 indicates that 12.5 lbs / acre should be used. If<br />

problems occur or questions arise regarding seed, call the<br />

<strong>Alaska</strong> <strong>Plant</strong> <strong>Materials</strong> <strong>Center</strong> at (907) 745-4469.<br />

Seed stored on site should be kept cool, dry, and in rodent-free<br />

areas. Remember seed is a living commodity.<br />

A bag may contain seed; however some percentage may<br />

be dead husks - the equivalent <strong>of</strong> cadavers. Always buy<br />

seed based on the PLS Calculation.<br />

<strong>Alaska</strong> Certified seed tags<br />

Pre-certified class seed tags<br />

Certified Seed<br />

The term “certified seed” can<br />

be used in two different situations.<br />

The <strong>of</strong>ficial use <strong>of</strong> the term<br />

Certified seed (with a capital C)<br />

is to describe seed that has been<br />

grown under the rules <strong>of</strong> the<br />

Seed Certification Program. Certified<br />

seed is the usual commercial<br />

category <strong>of</strong> seed. Its ancestry<br />

can be traced back to Registered<br />

Class or Foundation Class seed. In addition, Certified seed<br />

must meet various standards <strong>of</strong> purity and germination.<br />

These standards are a means <strong>of</strong> verifying authenticity <strong>of</strong> a<br />

seed source. All <strong>Alaska</strong> developed seed varieties or cultivars<br />

can be sold as either Certified or common.<br />

Seed can also be certified (without a capital C) to be free<br />

<strong>of</strong> weeds or as meeting a minimum germination standard<br />

(11 AAC 34.075). This has nothing to do with variety identification<br />

— it simply indicates the quality <strong>of</strong> the seed. In<br />

other words, the buyer knows quality, but has no assurance<br />

<strong>of</strong> type (other than species).<br />

Certified seed should be used when available. Seed<br />

produced in <strong>Alaska</strong> is easy to trace to its origin. It may<br />

be classified as common (uncertified) ‘Arctared’, but it is<br />

still ‘Arctared’. Minimum purities and germination should<br />

always be stated with orders. Common seed is a usable<br />

product and may be used to meet demands. Common<br />

seed should meet Certified standards<br />

with regard to germination<br />

and purity, although these standards<br />

may need to be relaxed<br />

to acquire sufficient material for<br />

a large job. Lower germination<br />

rates can be overcome by increasing<br />

the seeding rate. Lower purities,<br />

however, should be avoided,<br />

as weeds can become a problem.<br />

Other Certification Classes<br />

When purchasing seed, a buyer should be aware <strong>of</strong> the<br />

differences between certification classes. Many new<br />

sources <strong>of</strong> native seed are being developed in <strong>Alaska</strong>.<br />

Generally, these will not be sold as Certified seed. They<br />

may carry the following designations: ‘Source Identified’,<br />

‘Tested’, or ‘Selected’. These classes will be consistent<br />

with the certification standards <strong>of</strong> germination and<br />

purity, however the term ‘Certified seed’ will not apply.<br />

These classes are called ‘Pre-certified’ classes.

Definition<br />

The indigestible portion <strong>of</strong> a forage sample. It is measured much like NDF except that a forage<br />

sample is boiled in an acidic detergent. The boiling removes sugars, fats, starches, proteins, and<br />

hemicellulose. The amount <strong>of</strong> ADF residue is inversely related to energy so high quality forages<br />

have low amounts <strong>of</strong> ADF.<br />

A descriptive term to indicate the relative age <strong>of</strong> plants.<br />

The application <strong>of</strong> soil and plant sciences to soil management and crop production.<br />

Chemical inhibition <strong>of</strong> one plant by another.<br />

Amino groups with at least one carboxyl group, linked together in a definite pattern to form a<br />

protein molecule.<br />

<strong>Plant</strong>s that die after completing their life cycle within one growing season.<br />

Stage in floral development when pollen is shed.<br />

Living in the absence <strong>of</strong> free oxygen; the opposite <strong>of</strong> aerobic.<br />

Compounds like alkaloids, tannins, and other toxic compounds that cause problems in animal<br />

health and performance. Even if <strong>of</strong>ten present in small amounts, they can override the nutritional<br />

value <strong>of</strong> forage, even when the forage tests high for CP and TDN. Tall fescue endophyte contains<br />

a major anti-quality component. Sericea lespedeza is high in tannins, especially when mature.<br />

A specific type <strong>of</strong> allelopathy where the presence <strong>of</strong> adult plants <strong>of</strong> a species interferes with the<br />
