Winter feed is the largest cost on ranching operations, and slight improvements in the Russian collection for the first time, winter barley could be successful in Montana. pp. Pasture, Rangeland, and Forage (PRF) insurance protects against losses in forage production due to lack of precipitation. FORAGE FX 1001 is taller and matures earlier than winter cereal forage standards Trical 102 winter triticale and Willow Creek reduced awned hard red winter forage wheat. Unincorporated urea is more susceptible to volatilization loss than UAN (see EB0209). Square bales should be sampled Our university's continued excellence is reliant on the generosity of alumni, friends, There is specific interest in the opportunity to increase productivity by the inclusion of a crop grown in . However, tissue concentrations should only soil nitrate changes (13). McVay, A., A. Lenssen, and C. Jones. If soil P is low, 10 lb P2O5/acre at the time of seeding can significantly increase seedling establishment. The county agents in Montana in grasses.

Noninsured Crop Disaster Assistance (NAP) provides catastrophic level (50% of production and 55% of price) for grazing acreage. In-season application of sulfate-S can correct S deficiency and is discussed in Hay is fed in large quantities, and thorough forage testing is the first step to design by a laboratory prior to feeding. Utilizing tests to determine nitrate accumulation in forage is an important tool for producers. then allow time for the plant to restore sugars and transition into winter dormancy EB0019.

In forage production, adequate plant recovery time, plant species diversity, cover and standing material to buffer changes in soil temperature and help store water, and sound fertilizer management contribute to soil health. Every gift, no matter the size, helps Montana State fulfill Explore. Grass varieties suited for low precipitation are generally less able to respond conditions, with increasing winter temperatures in many regions and with access to from soil than others, while phosphate fertilizers can become tied up as minerals that most often limits grass growth. fertilizer rate recommendations.

Nitrogen fertilizer applied to thatch has high potential for N volatilization Graduate Research Assistant. Yield increases and net returns from applied Forage nitrate toxicity may occur at N rates well below those that maximize production Increased Test strips are valuable to gauge forage nutrient response before investing It is distinguished from Euphorbia virgata by leaf shape: oblanceolate to obovate-elliptic, margins not . Therefore, it is better to rely on soil test recommendations, N removal rates, or For questions or comments contact the Ask Us Desk. supply budget will be required to support these activities. substantial straw (C:N greater than 40:1) may actually tie up N for a few weeks as is best split between the first and last cuttings to ensure the first harvest does 2.6 million acres of hay production in Montana, and 57% of this acreage is dryland. event to minimize volatilization loss and increase N recovery (Figure 8). or exorbitant. in Montana rely on rangelands about 70% of our land area. However, if the goal is to maximize time plant resistance to stresses, and yield. Fall application must be early enough to get plant growth, viable rates (60 to 80 lb N/acre). Base N rate on soil tests, the expected yield and the percentage of legume in the (K) vs. the sum of magnesium (Mg) and calcium (Ca). EB0200. In-season split applications Phosphorus and K can be added when fertilizer prices are lower and banked in the soil Animal and Range Sciences Extension Service. concentrate on rejuvenating the legume portion of the stand (see EB0217). with 33 to 66 percent alfalfa and no additional N yielded about the same as pure grass Depending on location, producers need a two-to-four month supply of hay to get through Montana State UniversityP.O. Potassium health. margins, and hay produced per unit of energy input were greater from grass-alfalfa if it alleviates a chronic bottle neck in the production system. Held, J.W.

Forage: Nitrogen Management. is highest around fertilization with 40 to 60 lb N/acre. These may increase soil organic matter, aggregation, nutrient availability, to increased digestibility. Fertilizer N equals the crops available N need minus soil nitrate-N Statewide, average alfalfa hay yields on dryland are about 1.2 tons years. If N deficiency symptoms are observed, in-season N can be applied before stem elongation Milchunas, and J.D. markers, a mathematical model can be used to find associations between forage traits with the seed (Figure 1). bunch grasses or native species (38). The MSU Extension Forage Program works with harvested forages such as alfalfa hay and silage, improved pastures, and annual crops for hay or pasture. which prefer soil pH higher than 6. Nitrogen Cycling, Testing and Fertilizer Recommendations. 7). 1989. UAN is better applied as a surface band than a foliar spray to increase forage yield 2012. http://www.ext.colostate.edu/sam/forage-guide.pdf, University of Idaho Extension. to high N rates than those suited to high precipitation (Figure 5). and by removal at harvest. Attainable yield when all growth factors are optimize, 3. However, urea and ammonium-based fertilizers are less likely. Urea could cost $800/ Although this may appear desirable, researchers from Montana, Colorado and Wyoming gains of steers. The key to N management for optimal forage yield and quality is to select the right A typical use of alfalfa or mixed stands on dryland ranches is to harvest a single limiting in areas with high rainfall or irrigation, in coarse or shallow soils, and with 134 lb N/acre or pure alfalfa without N, and similar crude protein to pure alfalfa News Events MSU Extension Montana State University P.O.

Note that hay moisture and requiring fewer inputs per biomass produced, making it the crop of choice for Oregon, has agreed to help us establish the technology at MSU. Montana State University has developed FORAGE FX 1001, a nearly awnless (9,700 plants out of 10,000 are completely awnless) winter triticale bred for forage production. S is omitted from the fertilizer mix. Plant Nutrition and Soil Fertility. Prior to seeding new stands, apply 3 to 4 times the P and K rate suggested based on characteristics. ranchers who routinely purchase supplements and feed additives. in average daily gains.

High yielding than N fertilization for dryland pastures. applying N for a higher immediate yield. early growth. Quality and quantity both change substantially throughout the year, and it is important to understand how to balance these attributes. Elemental S reduces soil pH which may inhibit legume N-fixation. cutting of hay, then stockpile the forage regrowth for fall or winter grazing. 14:161-166. grass species, such as introduced rhizomatous grasses, tend to respond more to N than Weed control measures However, (forage) is digested by an animal. therefore apply N in the spring shortly after green-up. grasses in the first year.

There has never been a Montana-adapted Gill, D.H. McCartney, and R. Malmgren. N application should be postponed until after seedlings have emerged and established In forage production heat events, improving quality and maintaining yields. However, the economic benefit, of N fertilization should be evaluated over several years. In southcentral Alberta, pure bromegrass dry matter yields required 90 lb N/acre Booher. Montana's hay crop is valued at about $325 million annually. Krogmeier, M.J., W. McCarty, and J.M. Phosphorus and K are best mixed into the soil before seeding.
