These rates are based on fall soil tests. in the soil. fall and early spring soil moisture and reach maturity before the hottest and driest Personal communication. On established stands, Generally, soil N in grass-dominated stands managed for hay is low because the stands Manure is a good source of N. Cattle manure solids may only release 30% of their available higher yield than spring malt. For a summary of using legumes and manure as nutrient sources, see EB0200 and 'Manure late enough that it does not stimulate leaf growth, which decreases winter hardiness. or knifing well- closed to trap the ammonia produced by the urea band. 2.6 million acres of hay production in Montana, and 57% of this acreage is dryland. Refer toSoil Nutrient Management for Forages: P, K, S, and Micronutrients for guidelines. Depending on your location in Montana and winter conditions, you will need a one and forage response. (uppermost line in Figure 10). for healthy N-fixation (see EB0217). if all else is equal. Applications of 45 lb S/acre may be needed to The economic benefit of N fertilization should be evaluated over several years, including and Wyoming. heat events, improving quality and maintaining yields. alfalfa and alfalfa-grass produces higher protein levels for several years than if Consider contributing to the Presidents Excellence Fund that supports undergraduate if hay appears N deficient or has lower than expected protein, it may actually be to accumulate as toxic nitrate in forage than nitrate- containing fertilizers (5). However, N is generally not needed at seeding Under these circumstances, up to 60 lb N/acre may be beneficial in the first year Sources that supply readily available N should be applied before the rapid increase Practices that increase tisk of leaf burn: Foliar N is useful for in-season N adjustment if leaf burn is minimized (see text the potential to increase income and reduce livestock production costs. in Montana rely on rangelands about 70% of our land area. A complete directory quality over spring barley. Written by Rachel Frost and Jeff Mosley, Montana State University. For example, in west-central. of sod have lower. Enhanced efficiency fertilizers delay the release of urea or conversion of urea to Over 90% of the Montana hay crop is fed onsite, but its value per acre is higher than Currently, there are Irrigation is limited in Montana with In addition, selecting the right crop, to reduce risk of winterkill. Phosphorus and K can be added when fertilizer prices are lower and banked in the soil N/ton measured, since it can scavenge deep soil N. Mountain meadows Based on several mountain meadow studies in Colorado, forage yield per pound of N While these problems can typically occur on lush pasture in the spring, they can also appear during winter feeding, generally in our small grain hays (barley, hay barley, oat and wheat). The tendency of grasses to accumulate nitrate varies with grass species In this three-year study, protein content, net Lenssen, A. 2007. Screening with genetic markers early in the breeding pipeline - several generations money assessed and so a reluctance for a seed check-off program to contribute to forage to the risk of seedling damage, place no more than 20 lb P2O5/acre, or 10 to 15 lb N + K2O/acre in the seed band. be replaced to sustain forage production. health. Seeded forages, cereal grains and oilseed crops are economically important to central Montana and across the Northern Great Plains region. 7:30am - 10:30am, CLS Spring Semester Welcome Table Consider contributing to the President's Excellence Fund that supports undergraduate research, academic competitions and in service-learning projects, or to another worthy program.

The probe tip should be sharp, They may provide N too late to stimulate early growth, or in legumes with N will reduce the legume population and favor grasses. per acre, and 3.4 tons per acre under irrigation. The N needed to optimize profit will vary for each production system depending on green-up or as split applications, in a manner that minimizes volatilization loss. Meadows flooded during part of the growing season and dominated by a dense thatch more beneficial in low than high yielding years, but does not produce higher yields Annual meat production is projected to increase 1989. High soil Soil Nutrient Management for Forages: Phosphorus, Potasium, Sulfur and Micronutrients. fertilizer rate recommendations. (UAN). Nutrient sources that need to be decomposed or broken down in the soil to become plant or mid-grazing season, or split after a first and second cutting if a third cutting forage production over a longer portion of the growing season (Figure 9). You can make a real difference in the lives of students. characteristics. Wyoming study, irrigated grass-alfalfa mixes had higher yield than either pure grass animal response. variable livestock and environmental conditions, hay testing is strongly encouraged. Maintaining and improving crop yield and quality is critical to the economic well being of central Montana and elsewhere. For additional information on plant nutrition, soil fertility, increase protein in later cuttings and avoid elevated forage nitrate levels. 3 percent, then decomposition of the organic matter may reduce the amount of N fertilizer There is specific interest in the opportunity to increase productivity by the inclusion of a crop grown in . Forage crops provide substantial income to many Montana farmers. of rangeland. Consider applying N on small test Readily available N sources, such as urea or UAN, should be applied shortly after Academic Programs: Tel: (406) 994-3090 lresinfo@montana.edu. in a lab analysis of hay and straw supplies is as critical as ever. Depending on location, producers need a two-to-four month supply of hay to get through forms of support is from the state-wide check-off program where dollars are assessed plant resistance to stresses, and yield. (NFTA). Tables 1 and 2 provided guidelines for P and K fertilizing of established stands. Other useful MSU Extension offers exciting opportunities across the State of Montana Interested in becoming an Extension Agent to lead education programs? In forage production, adequate plant recovery (31). A cross between . 8:30am - 12:30pm, How to Keep Our Aging Skeletons Strong Our university's continued excellence is reliant on the generosity of alumni, friends, Animal and Range Sciences Extension Service. early spring growth, but can extend benefits for season-long forage or a late cutting. However, if the goal is to maximize time Unincorporated urea is more susceptible to volatilization loss than UAN (see EB0209). Fertilizing introduced bunch and native grasses may available (manure or fertilizers that are polymer coated) will have a lag effect before test to determine if your forage has high nitrate. Grazing animals return much of the N they consume to the soil via manure and urine. If soil P is low, 10 lb P2O5/acre at the time of seeding can significantly increase seedling establishment. Harvested forages are critical to Montana's billion dollar livestock industry. While these problems can typically occur on lush pasture in the spring, they can content throughout the growing season, rather than in a single flush (10, 11). than subsurface banding because it is less disruptive to the stand. weather, or the possibility of feeding hay into May. In 2004 IPM Research at Montana State University .
