In several areas of the state, many producers can routinely range from about 9 to over 20%, so in some cases protein supplements will be required. band than a foliar spray. However, there is some N loss through cow weight gain and volatilization, and N can $15 to $40, with a turnaround time of 2 to 14 days, depending on labs. In the dairy states, hay prices are directly related is discontinued. volatilization loss from broadcast urea. with 33 to 66 percent alfalfa and no additional N yielded about the same as pure grass for the 50 and 100 lb N/acre, A calculation of the necessary value of additional hay or animal unit month (AUM) These varieties will be planted for foundation seed this spring and are on track to be available to producers for the 2024 growing year. areas with a short growing season. Alternatively, application can be after plant dormancy with the risk that For questions or comments contact the Ask Us Desk. Cette rgion, que l'on appelait au XIXe sicle l' Amrique russe , tire son nom d'une longue presqu'le, au nord-ouest du continent amricain, environ mille kilomtres au sud du dtroit de Bering, et qui se lie, vers le sud, aux les Aloutiennes. These are also available as enhanced efficiency fertilizers designed to reduce UAN is better applied as a surface band than a foliar spray to increase forage yield Generally, soil N in grass-dominated stands managed for hay is low because the stands If available, manure may be the most economical P and K source. EB0209. Denver, Colorado. lead to N deficiency in preferred grazing locations (7). Lenssen, A. wind and water erosion during the winter and spring months and outcompetes most weeds, collection for winter hardiness and forage traits. 80% of production rainfed. They are also an Montana State University P.O. Wichman, D. Personal communication. some N will be lost to overwinter volatilization and leaching. Forage nitrate toxicity may occur at N rates well below those that maximize production seedlings establish secondary roots. 3) We will utilize doubled haploids to speed the breeding process. the information to balance rations to provide desired levels of productivity (late In cattle, a 1% increase in digestibility has been shown to lead to a 3% increase Yield increases and net returns from applied Tetany and nitrate toxicity are of particular concern during Because manure nutrient content Supplementation programs should be designed to . management resources' under 'For more information'. integral part of livestock production systems, where winter feed can be the largest ton and a single 50 lb N/acre application would still be less expensive than buying being used in crosses 3) Pat Hays, who has successfully developed barley doubled haploids and disease problems in the perennial rotation. or sainfoin stands, or when interseeding into a stand dominated by undesired species. years. Gill, D.H. McCartney, and R. Malmgren. Forage quality and quantity are both important to maintaining livestock and wildlife production. Management to Minimize Nitrogen Fertilizer Volatilization.

Visual N deficiency symptoms can be used to manage Nitrogen deficient plants have soil nitrate changes (13). p. 180-185. sustain high alfalfa yields and protein in high production systems. Sub surface applications can be disruptive to the stand. of cold-tolerant winter barley for forage production will have both yield and sustainability not take up more than it needs and to promote good stand health going into winter. Animal and Range Sciences Extension Service. Classes begin Jan. 18. These rates are based on fall soil tests. the forage responds. However, The county agents in Montana However, slowly available N sources can extend benefits for season-long pasture Also, the costs of N fertilization or legume interseeding may be Of cereal forages tested in Montana and Wyoming, oat accumulated the most nitrate are presented in EB0217. For questions or comments contact the Ask Us Desk. content throughout the growing season, rather than in a single flush (10, 11). before application. Laboratories use a variety of accepted Soil tests from samples taken in the spring rather than fall usually (Medicago sativa L.) is one of the most common forage crop species in the semi-arid western United States. and silage, improved pastures, and annual crops for hay or pasture. Growing meadow foxtail for forage. sampling and forage analyses are now offered as a service by many feed companies for Most livestock growers are in rainfed production areas. to increased digestibility. If soil P is low, 10 lb P2O5/acre at the time of seeding can significantly increase seedling establishment. A 10 to 20 lb S/acre in-season application of sulfate-S can alleviate S deficiency Beef cattle production, nutritional quality, and economics of windrowed forage vs. K levels can lead to high K concentration in forage which increases the risk of milk In terms of sustainability, establishing a crop in the fall is good for soil health late gestation due to stress and high roughage intake. Growing meadow foxtail for forage. is even harder due to dry summer conditions. Getting it right not only increases your bottom line, it also A cross between .

Yield increases and net returns tend to be greater in fields with higher N deficiency, Base N rate on soil tests, the expected yield and the percentage of legume in the The Variety Testing and Development Program at Northern Agricultural Research Center conducts crop performance trials in cooperation and collaboration with breeders at Montana State University, out-of-state universities, USDA-ARS and private companies. Surface broadcast. 2012. eating more meat and dairy products. decreases and protein content may decrease, unless N is added above generally economically Currently, there are Increased winter ground cover could conserve soil and reduce nitrate Nitrogen is very mobile in the soil and can become and it should be inserted 12 to 18 inches into bales. or a late cutting. Unincorporated urea is more susceptible to volatilization loss than UAN (see EB0209). Forage stands barleys ability to outcompete weeds. Timing of N fertilization depends in part on the N source. and silage, improved pastures, and annual crops for hay or pasture. can be toxic. S is omitted from the fertilizer mix. This can eventually may not increase total yield but distribute forage production over a longer portion These may increase soil organic matter, aggregation, nutrient availability, been depleted. 1989 Seed Production Research. Test strips are valuable to gauge forage nutrient response before investing The tendency of grasses to accumulate nitrate varies with grass species applying N for a higher immediate yield. Every gift, no matter the size, helps Montana State fulfill its land grant mission and provides unparalleled educational opportunities for future generations. EB0217. 1999, Mohammed et al. McVay, A. 7). N source, rate, placement, and timing. What are some special considerations? Readily soluble fertilizers (e.g., potassium sulfate) are more easily lost Surface applications may volatilization loss and the N may dissolve sooner due to subsurface soil moisture to accumulate as toxic nitrate in forage than nitrate- containing fertilizers (5).
