Volesky said that varied soil fertility levels in Nebraska can indicate a need for anywhere from 40 to 70 pounds of nitrogen per acre. If the fertilizer is spread onto ground that is already wet and rain is not in the forecast for a few days, the evaporating water can attach to the ammonia gases released, and risk losing the urea content of the fertilizer. Different livestock producers will need to take different approaches based upon their location, resources available, and type of operation. . Following timing, amount, and location safety guidelines when adding fertilizer to a field can drastically help protect against waterway contamination, livestock poisoning, and waste of expensive fertilizer and any rental equipment used to spread it. The ideal ratio of fertilizer for this type of hay-producing field would be one part phosphorus to four parts potassium. 116 Agricultural Administration2120 Fyffe Road But producers need to first make sure that adequate moisture is present, and secondly, take care not to overgraze. https://extension.soils.wisc.edu, Applying Manure to Alfalfa. Applying fertilizer just once, annually, would not add essential nutrients back into the soil at the necessary ratios after the hay has been harvested or the pasture grazed clean after a livestock rotation into it. 
A hayfield soil test may have called for 12-12-12, 15-15-15 or a 19-19-19 mixture in March definitely does not mean the soil composition will call for the same recipe mix after months of grazing, growing, and harvesting. 
But, be sure to use the types and amounts of fertilizer that work best for the plants in your hay meadow. Applying manure before alfalfa seed is planted is excellent for alfalfa production while avoiding many problems associated with surface application on established stands. Depending on the rate applied, supplemental fertilizer N may be needed for maximum hay production. Legumes can provide up to 150 pounds of N per acre, enough to produce up to 3 tons of dry matter per acre. Manure is an excellent nutrient source for fertilizing hay fields, especially with current high fertilizer prices. Adding in 275 pounds of a 19-19-19, a potent fertilizer mixture recipe, would still leave the field roughly 148 pounds shy of the level of potassium that has to be replaced to achieve optimal soil contents. Stopping ammonia volatilization from urea can occur if the crystals have direct contact with the dirt and enough rain falls soon after the fertilizer is applied, the urea content will wash from the residue of plants in the field down into the dirt. The urea is the crystal and colorless compound in nitrogen that breaks down the protein in urine excreted by animals. Copyright 2022. Wetter regions and irrigated fields are more likely to give a much greater return for investment, while drier, arid areas will see a smaller increase in tonnage. The actual rate should be 50 lb N/ton of expected hay yield. Were definitely in crunch time before we are in the field mowing that first cutting of hay; however, Bruce Anderson, University of Nebraska-Lincoln Extension forage specialist, says there is still time to fertilize hay fields this spring in order to grow more hay for next winter. Jerry Volesky, University of Nebraska-Lincoln professor of Agronomy and Horticulture, says that soil testing is a good first step in determining just what each fields soils may need. At home on the ranch in South Dakota, were hustling to get heifers and cows synchronized and artificially inseminated, move creep feeders to pasture, fix fences and line up help for moving pairs to summer grass. If so, when and how much? Solid hayfield and pasture management practices begin with soil testing. In addition, a single fertilizer recipe mix might be perfect for one hayfield, but be entirely wrong for an adjacent one or a nearby pasture. Typically, one soil sample may adequately address the type of dirt over a 20 acre patch of land if the area is similar in drainage capacity, soil type, and topography. Manure should be applied as soon as possible after cutting to reduce potential injury to the regrowth. If you have a disability and experience difficulty accessing this content request accommodation here. On the average, a ton of fresh broiler litter will contain at least 60-60-40 pounds N-P2O5-K2O.
In some cases a legume/grass mixture may produce more dry matter per acre than grass alone, particularly as compared to grass receiving little or no N fertilizer. Research has shown that in many poorly managed continuous grazing situations, less than half the forage produced in a pasture ends up being consumed by livestock. Phone: 740-223-4043, 2022| 2120 Fyffe Road | Room 3 Ag Admin Bldg. These practices can greatly improve soil health and nutrient levels, but they are not always possible due to location and availability of water and winter protection..
Phosphorus and potassium will build up in all our soils. University of Wisconsin Cooperative Extension Service. If you do not know what nutrients the soil lacks or has an overabundance of (or the pH balance), it would be impossible to choose the right fertilizer for the area or know how much should be applied. First, is the value of the nutrients in the material high enough to justify the cost of obtaining and applying it? However, the single most valuable advantage forage legumes offer is better forage quality on average than grasses, which usually sharply increase animal gains and may enhance livestock reproductive rates, he says. It is not recommended to add nitrogen on alfalfa as it is a legume and should not need any additional nitrogen, Bauder said.
Example: 12-12-12 fertilizer grade is composed of 12% nitrogen, 12% phosphate, and 12% of potash.
In addition to providing biological N, legumes offer other potentially important advantages.
Pastures tend to benefit significantly more than hayfields from the natural fertilization cycle. Consider the potential for forage contamination with the Johnes disease. Once you know how much the ground needs you can figure the cost of fertilizer and get a pretty good idea of what kind of a return youd be looking at based on the value of the hay. Hayfields are often best fertilized AFTER the first harvesting of hay or straw. Johnes bacterium is not absorbed by plants, but resides on manure and soil particles for a limited time.
We work with families and children, farmers and businessowners, community leaders and elected officials to build better lives, better businesses and better communities to make Ohio great. Getting the fertilizer in place prior to plant growth in the spring is ideal. These natural benefits can be applied to hayfields by grazing them in the fall or early winter. A lack of moisture can also increase risk of nitrate toxicity in plants.
Agriculture and Natural Resources Producers should be prepared to manage the increased weed pressure with timely harvests or herbicides. Grazing livestock recycles nutrients. Legume and grass-style hay will nearly always flourish in the spring without the need of any fertilizer because it has had all winter to rest and build up nutrients. As an Amazon Associate I earn from qualifying purchases. Breaking down what the three numbers in bold print actually mean will help you understand not only what you are buying, but what you need to give your hay fields and pastures both before the growing season starts and after each harvest. The next step is to push a pencil to determine whether investing in added fertilizer will pay off. Number 8860726. How much and how quickly this type of surface volatilization occurs will depend on several factors: the pH balance of the soil, moisture levels, and temperature. We can grow a little grass without fertilization because Mother Nature usually gives us about 20 to 30 pounds of N per acre per year in rainfall. Topdressing hay fields with manure can build soil fertility with on-farm resources and help expand acres for spreading. Alternatives available for fertilizing pastures, hay fields, Awareness crucial for mental health intervention, Study looks at declining Oklahoma wild turkey population, Shrinking cattle herd could equal high calf, beef prices, Southwest cotton organizations report on crop status, Keep an eye out for algae overgrowth in ponds this summer, Peanut industry gathers to discuss progress, challenges ahead, Allowed HTML tags:
When the spring flush growth occurs after winter finally subsides, adding fertilizer to bolster the ample sweet grasses in pastures even more could actually be harmful to the livestock. | Columbus, Ohio 43210 | 614-292-6181 The second factor is whether the material contains any pathogens, heavy metals, or other undesirable components that could be harmful to animals, humans, or to the soil.. Most hayfields in the upper Midwest are seeded with cool season grasses such as smooth brome, crested wheat grass or intermediate wheat grass. Web page addresses and e-mail addresses turn into links automatically.
What is an Alabama cattleman to do? asks Charles Mitchell, Auburn University Extension agronomist-soils. This site may earn commissions when you visit certain links. The lightweight fertilizer material clings to the filler, and helps in the dispersal process. If you have sandy soil in all or part of your fields, consider using split percentage levels of nitrogen to avoid infusing too much of the nutrient into the soil and increasing the possibility of leaching. Potash can help improve winter survival as well.. The soil will be depleted of nutrients, and need a little help for the next cutting to grow tall and healthy especially if the fields are cut three times a year when weather permits instead of the standard two. If manure is not spread between hay cuttings it should be stored and spread in the fall when manure nutrient use efficiency is generally very low. • There are fertilizer alternatives, but none of them are cheap. This application should be limited in acreage for pastures, based on how much grass growth is needed to carry the herd or flock. Driving heavy manure spreaders on wet soils causes soil compaction. To answer this question requires knowing the level of nutrients in the material as well as how much will actually become available to plants. This gives the grazing area a solid nutrient boost before the dry heat and incredibly intense temperatures start to appear.

C.O.R.N. Here in the Nebraska Sandhills, hay meadows can be pretty wet in April so some guys get their fertilizer down even earlier while the ground is still frozen, but April is the most common timeframe.. Nice article of good information, I will need to read couple of time to catch all you have said. Rain and snow also nitrogen to the ground, and roots of legumes such as alfalfa fix nitrogen in the soil. Informa Markets, a trading division of Informa PLC.
If there is little to light residue it should only take one quarter to half of an inch to dissolve the urea into the dirt. Hay land soils should be tested annually and pastures every two to three years. Applying too much fertilizer is a waste of money; applying too little will result in less-than-optimum forage production. With phosphorus, for example, we did some testing on hay plots and we could see the phosphorus levels slowly decline each year to the point where yield was affected. What happens when we interrupt this process by removing a crop mechanically, year after year, without putting anything back?
The alfalfa seed should not be in direct contact with a manure layer during germination, and the seedling should not grow through a layer of manure at the soil surface. With the ample rain weve received in the last couple of weeks, things are really greening up around here, and we are itching to get into the summer grazing and haying season. Timing of fertilizer application is everything. Soils high in organic matter are more productive.
Some research in Wisconsin and Minnesota has shown manure can sometimes improve alfalfa yields when compared with commercial fertilizer sources.
