A light application of N, 20-40 lbs./acre in March could be used to jump start spring growth and allow for earlier grazing. growth may be a better way of adding “N” to pasture compared to a $40 investment in N fertilizer which only has a short term effect. The fertilizer recommendation for a legume-grass pasture with a yield of 4.1 to 5.0 tons of dry matter per acre is 60 pounds of P 2 O 5 and 240 pounds of K 2 O.
Now, I'm not totally opposed to fertilizing pastures in the spring.
Pastures that have significant percentages of broom sedge often need lime or phosphorus.
"Fall fertilizer doesn't seem to hurt clover (or other legumes) stands as much. • Application Rate – Total seasonal N applications can range from 50 to 150 lbs.
Most pastures can well use 50-100 pounds of nitrogen an acre in the fall application, Kallenbach said. Properly fertilizing pasture and hay fields often comes down to the 4 Rs. At that time, the grasses and legumes are growing together and not crowding each other so much." There are several benefits to using urea as a fertilizer, but urea is not without its disadvantages. … The only sure way to know is to soil test! In one study, recoveries were 85% for application rates of 25–50kg N/ha, and fell to around 50% when 100kg N/ha was applied. Urea fertilizer is a stable, organic fertilizer that can improve the quality of your soil, provide nitrogen to your plants, and increase the yield of your crops. You can usually get it in dry, granular form. By: Jennifer Bearden, University of Florida Extension Soil fertility and plant nutrient management is … In an intensively grazed pasture, on the other hand, over 80% of the nitrogen, phosphorus and potassium are recycled back to the pasture. Following are a few tips to help make the best economic use of your lime and fertilizer budget: 1. N … Possible problems from applying N fertiliser to annual pastures Reduced clover content: regular applications of N fertiliser favour grasses and broadleaf plants over legumes, and legumes can be reduced by competition. The difficulty is that N fertilizer shows an immediate effect, whereas, lime is much more subtle. Applications of P and K should be made prior to establishing a new seeding based on soil test results. In these soils, the most economic beneficial application would be that of lime rather than higher levels of fertilizer.
