nitrogen fertilizer for pastures

25-61-19, Strategies for Better Management of Pasture Fertilization. Fertilizing pastures with nitrogen, phosphorus, and potassium, as well as the addition of lime can help return nutrients to the soil and increase plant productivity. 0000002903 00000 n Some studies have suggested that in a rotational grazing system as much as 50 percent of the pasture surface area may be affected by urine in a single year. The first question to consider is if N fertilization is necessary. Three tons of grass hay that contains 12.5% crude protein will remove about 120 lb N/ac. You should know what soil pH is ideal for the type of forage species present before you apply any nutrients. 0000000016 00000 n Data from the first year of a study at the West Central Research and Outreach Center, near Morris, MN shows that even 200 lb N/ac on cool-season grass pastures (primarily bromegrass) was not as productive as a grass/legume mixed stand (Table 3). Simply put, N grows plant tops (leaves). 0000007599 00000 n xref Fertilizer is one of the major annual costs of maintaining an established pasture. Therefore, we suggest a late spring application of nitrogen. Spring is also a good time to overseed existing cool season pastures - provided you can seed in February or early March before the temperatures rise too high. After soil testing match the recommended nutrients needed to the N-P-K ratio in your fertilizer. Progressive Forage is the Forage Industry Resource for progressive hay, silage and pasture producers. Like with most things, Bosworth points out that there are exceptions to the rule. 0000008437 00000 n How much forage is needed for the animals? 0000004591 00000 n 0000003804 00000 n All rights reserved. As soil pH decreases when pastures are depleted, elements that are toxic to plant roots are released by the soil particles and the nutrients that plants need to grow become bound in the soil. 0000001416 00000 n It doesnt have to be perfect, but if you have a really weedy pasture, N is going to do nothing but increase the competition of those weeds with your desired species.. If you currently produce enough forage to meet your grazing and/or hay needs, then additional N is probably not necessary. Rotational grazing creates high stocking rates in small areas, which usually helps distribute nutrients in pastures. However, N is often not evenly distributed by grazing animals. 0000002640 00000 n The listed rates are for all forage grasses and grass mixtures. All editorial content for Progressive Forage is driven by one primary goal to provide informational resources that ensure success for forage producers. My opinion is that if you are applying 50-75 lb of N/ac/yr, apply it in mid-June to stimulate summer production. He also suggests applying N in split applications throughout the season, with a single application of 50 pounds being the target per acre. It may make more sense in a grazing operation to apply fertilizer in mid- to late-June. Williamson points out that N isnt your answer to grass growth during a dry year. Fertilizing with nitrogen is a short-term management tool because its effect is usually immediate and lasts only one grazing cycle. Although P, K and lime can be added anytime, nitrogen fertilizer should be applied when pastures or hayfields will have the best opportunity to have a yield response. Digital Media Library, an educational program to improve grazing practices in beef, dairy, goat and sheep herds, http://www.ca.uky.edu/agc/pubs/agr/agr1/AGR1.PDF, College of Agriculture, Food and Environment. One alternative is strategic N fertilization. 2EdfGAGy}}AWWWzCOOOOOe/E/e"GQ(rLe|w\_*****WFglt68 Fglt68 Fg 0000003468 00000 n PHOTO: If used correctly, nitrogen fertilizer can be used to improve pasture productivity and utilization throughout the grazing season. Therefore, the previous crop is not a consideration when making fertilizer guidelines. Most grass pastures only require late summer applications because extra N in the spring often produces more growth than livestock can consume. 25-61-19, This site was last modified on: Jul-29-2022 11:59 amhttp://extension.msstate.edu/publications/strategies-for-better-management-pasture-fertilization, Grazing Systems, hay production, forage fertility, forage quality and utilization, alfalfa productio, STEM Science Technology Engineering and Math, Thad Cochran Agricultural Leadership Program TCALP, Mississippi County Elections: Election Prep 101, Extension Center for Economic Education and Financial Literacy, Creating Healthy Indoor Childcare Environments, Plant Diseases and Nematode Diagnostic Services, Bermudagrass stem maggot is fairly new pest of pastures, MSU Extension hosts grazing system field day, New program helps farmers learn, practice stewardship, Preventing and Managing Herbicide-Resistant Weeds in Turfgrass, Adjusting Soil pH in Mississippi Landscapes, ORNAMENTAL GRASSES for Central Mississippi, Tips for Overseeding Annual Ryegrass or Small Grains into Perennial Warm-Season Pastures in the South. For pasture grasses, such as fescue or orchardgrass, an ideal pH ranges from 5.6-6.2. For information about the website contact webteam@ext.msstate.edu. Ball, D.M., C.S. 0000008308 00000 n The amount of N legumes fix varies based on species, soil conditions, water availability, and other seasonal factors (Table 3). All Rights Reserved. 1993. Late-summer/fall establishment of grass is often desired in the Midwest. These include soils with good water holding capacity and intensive management practices, like rotational grazing. Supplying N to pastures by growing legumes or with animal manure can be an excellent option. This publication may be copied and distributed without alteration for nonprofit educational purposes provided that credit is given to the Mississippi State University Extension Service. 0000367032 00000 n In most grasslands, the two factors that most limit growth are moisture (rain) and N. There is not much we can do about the weather; however, we can manage N to improve productivity on pastures. 2002. This allows clover plants to fill in bare spots and improves forage quality and yield. Legumes can provide 80-100 lb. Growing more grass does not make fertilization profitable. 1.219. 2022 The Mississippi State University Extension Service is working to ensure all web content is accessible to all users. c?{k/56s>|q]_W 8 Have you participated in any USDA relief programs in the last two years?

Copyright 2020 Progressive Forage. 0000009319 00000 n 0000011353 00000 n To develop a fertilization plan that will be effective, it is important to first understand the needs of your soil. Producers should take soil samples once per year from hayfields and every 3 years from their pastures. Producers with many acres of pastures on relatively unfertile land are often hesitant to use. In periods of limited soil moisture, delaying fertilizer application until moisture is present or imminent can also increase efficiency. Bosworth and Williamson encourage producers to think of N as a short-term management tool for producing temporary increases in pasture growth. In addition to being a primary environment for livestock, your pastures are also a valuable resource as a feed solution for your animals. Table 4 compares the costs of applying nitrogen fertilizer versus interseeding red clover. The moisture and cool temperatures of spring allow the plants to respond well to the nutrient application. If soils are lacking in P and K, the pastures will not be as responsive to N. Nitrogen fertilization should be part of an overall fertility program. If you are planning to stockpile your grass for winter grazing, applying N in early to mid-August can help accumulate growth.

This is understandable since the cost of fertilizing all those acres would be quite high, and the economic return may not be good. 0000009987 00000 n The number of times a parent says the word no in a day can feel almost endless. 0000003178 00000 n The cost for a custom no-till drill is $20 per acre. 0000002760 00000 n Grazing for shorter periods with more pounds of animal per acre can help with N (manure and urine) distribution. This leaves grass pastures and hay fields deficient towards the middle through end of the growing season. Hayfields need to be checked more frequently since large amounts of nutrients are removed in hay. 0000314446 00000 n For pastures that require the addition of P or K, a spring application will encourage an increase in late summer production, providing a valuable and cost effective food source for your livestock. If split application is an option, apply 3/4of the nitrogen in early spring and 1/4in late August.
