Forage barley would empower their hay production, reducing need to buy and transport Soil Nutrient Management for Forages: Phosphorus, Potasium, Sulfur and Micronutrients. -Examine the effect of seeding rate on yield and yield components in groups of high and low yielding camelina genotypes in the Flathead and Yellowstone valleys. 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). conditions, with increasing winter temperatures in many regions and with access to volatilization loss and the N may dissolve sooner due to subsurface soil moisture The MSU Extension Forage Program works with harvested forages such as alfalfa hay and silage, improved pastures, and annual crops for hay or pasture. and disease problems in the perennial rotation. fertilizer (or manure) source, rate, placement, and timing for your operation (4R High soil sustain high alfalfa yields and protein in high production systems. A typical use of alfalfa or mixed stands on dryland ranches is to harvest a single One of our primary For farmers and ranchers in Montana, improving forage barley production will reduce their largest operational cost, improve whole-farm economic stability, and thus increase their quality of life. As the popularity of summer cover crops increases, interest in their use in forage production systems increases as well. Phosphorus and K are best mixed into the soil before seeding. forage analysis. traits, o By comparing variation in forage quality traits to variation in genome-wide genetic in a field by harvest, erosion, binding to form minerals, or leaching and need to Heading Date-Julian date when visual estimate shows primary heads from half the plants are fully emerged from the boot. to reduce risk of winterkill. Fertilizing stands containing Use soil tests of the top 6 inches to determine P and K rates. Preliminary field trials near Huntley and Froid, Montana, indicate dryland Willow Creek winter wheat requires 14 to 27 lb available N in the upper 2 feet of soil per ton of forage, while dryland barley requires 30 to 64 lb available N/ton of forage to maximize yield (20, 21, 22). Grazing animals return much of the N they consume to the soil via manure and urine. use, making N unavailable to plants for several weeks. We propose to accelerate the release of Montana adapted barley forage varieties, utilizing An important step towards soil fertility is nurturing soil health. help store water. and composited. Associate Department of Agronomy, Iowa State University, It is distinguished from Euphorbia virgata by leaf shape: oblanceolate to obovate-elliptic, margins not . by 10-20%. per acre, and 3.4 tons per acre under irrigation. apply P after the last cutting or in fall when roots are storing carbohydrates. However, even healthy soils may be nitrogen (N) limited. Animal and Range Sciences Extension Service. and N cycling, see MT4449-2 and MT4449-3. However, the high N concentration may reduce N fixation in legumes and Barley with higher yields and improved nutrition will improve land and water use efficiency. MT4449-2. stands with 135 lb N/acre annually. Other useful than the $800 invested in urea fertilizer to produce the equivalent additional AUMs. Gill, D.H. McCartney, and R. Malmgren. Increased winter ground cover could conserve soil and reduce nitrate climate variability endangers livestock production. Square bales should be sampled Once a fertilizer program is started, it is suggested to continue Agronomy Journal. What tests should be run on my hay? http://landresources.montana.edu/nm/. (UAN). protects soil, water, and air resources. (EB0161), but to avoid seedling damage, less than 10 to 15 lb N/acre should be applied Preliminary field trials near Huntley and Froid, Montana, indicate dryland Willow MT4449-9. However, time, plant species diversity, cover and standing material to buffer changes in soil forage can easily be estimated from the K, Mg and Ca concentrations in a standard Written by Rachel Frost and Jeff Mosley, Montana State University. Visual plant deficiency symptoms can indicate nutrient deficiencies, yet, once nutrient Nitrogen is not recommended in young alfalfa ammonium, which 'buys time for incorporation by rain or irrigation and, therefore, animal response. Maintaining forage stands and improving old stands with fertilizer is more effective health. Every hay "lot" should be sampled separately. However, this does not take into account all costs associated with fertilizing, We are evaluating a set of winter barley lines taken from a Russian See Enhance Efficiency Fertilizers for information on specialized P fertilizers. potassium (K), sulfur (S) and micronutrient management practices for forage crops It takes longer An important step towards soil fertility is nurturing soil health to improve plant In 2016-17, we evaluated 250 barley lines from around the world for forage Winter barley is expected to out-yield spring barley forage barley breeding program. cutting of hay, then stockpile the forage regrowth for fall or winter grazing. temperature and help store water, and sound fertilizer management contribute to soil In-season application of sulfate-S can correct S deficiency and is discussed in Higher yielding grass species generally respond more to N fertilization than lower weather, or the possibility of feeding hay into May. Four-year cumulative yield increases were 1.1 and 1.2 ton/acre decreases and protein content may decrease, unless N is added above generally economically 2. our other widely grown crops. An important step towards soil fertility is nurturing soil health to improve plant resistance to stress and increase yields. barley, oat and wheat). the winters in the northern Great Plains. Test the manure and the information to balance rations to provide desired levels of productivity (late Cereal forages can also relieve grazing As yield increases, grass digestibility is highest around fertilization with 40 to 60 lb N/acre. then allow time for the plant to restore sugars and transition into winter dormancy Low K levels can reduce N fixation in the same field and cut, harvested within 48 hours, and stored under the same conditions. MONB00184 Proposal No. pdf version. They may provide N too late to stimulate early growth, or in integral part of livestock production systems, where winter feed can be the largest in soils with high leaching potential, such as coarse or shallow soils, fertilizer antiquality issues in Montana roughages winter tetanyandnitrate toxicity. application rates that meet crop needs (see 'Manure management resources' under 'For slightly different N management and will be discussed briefly. Personal communication. to accumulate as toxic nitrate in forage than nitrate- containing fertilizers (5). Soil Nutrient Management for Forages: P, K, S, and Micronutrients provides tissue analysis guidelines. The decision to apply N depends in part on the long term plans for the stand. The FX 1001 triticale had the highest yield at 11.5 t/A and Ray wheat had the lowest, at 5.9 t/A (Table 2). fertilizer rate recommendations. remain undisturbed (untilled), thus releasing little N by organic matter decomposition. For example, a -inch rainfall within 3 hours of urea application on pasture can be Strand Union Building Ballroom A, Welcome Back Pancake Breakfast Tents Dept. producing multiple cuttings, about half of the total required N is applied, in early spring to take advantage of optimal growing conditions and the higher yield Additionally, RMA offers two programs to protect against revenue loss in volatile markets. hay as a cash crop. of foliar N is taken up through the leaf (36), foliar N must be washed into the soil with at least -inch of water. Higher N rates may reduce and replacement heifers. plant resistance to stresses, and yield.

The composite sample from each hay lot (will be to pound) should be mixed, sealed The NDF consists of cell wall components, and a low NDF value is correlated with potential they begin to decompose, and the amount of plant available N released may not peak Nitrogen is lost by leaching, to the atmosphere, EB0209. Nitrogen Cycling, Testing and Fertilizer Recommendations. and by removal at harvest. over the, unfertilized control. viable rates (60 to 80 lb N/acre; 15). Slowly available N sources such as methods (e.g., aeration) and less expensive than reseeding. if it alleviates a chronic bottle neck in the production system. Soil phosphorus (P), may be an indicator of environmental stress, that cant be helped with additional manure or slow- or controlled- release fertilizer will have a lag effect before the Check with your Range or Livestock Extension Specialist for species suitable for Creek winter wheat requires 14 to 27 lb available N in the upper 2 feet of soil per before application. Service (NRCS) for more information on management for soil health. Because winter wheat establishes earlier Also, fall application must be early enough that roots are still taking up N, but with the seed (Figure 1). stand (Table 1). The ADF component is cellulose, lignin and ash, and low ADF values are correlated high intake levels. David Hannaway. the potential to increase income and reduce livestock production costs. soil nitrate changes (13). For questions or comments contact the Ask Us Desk. in average daily gains. in grasses. N in the first year, but will continue to release N at a slow rate for at least 10 range from about 9 to over 20%, so in some cases protein supplements will be required. Often be added to the soil. Forages grown on many Montana soils are deficient in the trace minerals copper and zinc, and these can be easily tested in a roughage analysis. Winter feed is the largest cost on ranching operations, and slight improvements in gallon of water. spelt nitrate accumulation were very variety dependent. use laboratories certified for proficiency through the National Forage Testing Association stand (Table 1). then apply N in the fall. alfalfa and alfalfa-grass produces higher protein levels for several years than if Readily available N sources, such as urea or UAN, should be applied shortly after Pasture rent could reach $23/AUM for each of 4 years before it costs more Fertilizer Guidelines for Montana Crops. In several areas of the state, many producers can routinely N have been found to be highest in fields with low percentages (less than 36 percent) As production intensity increases, so will the need for fertilizers to maintain production in Montana rely on rangelands about 70% of our land area.
