Nebraska Extension will host a Nitrogen Sources and Water Quality Field Day on August 13, 2024, from 9:30 a.m. to 2:30 p.m., at the Haskell Ag Lab near Concord, NE.
This year’s 4Rs Field Day will focus on up-to-date research information and demonstrations on all three major crop nutrients: nitrogen, phosphorus and potassium.
At the end of the season, a nitrate test can help determine whether the crop was under-, adequately or over-fertilized with nitrogen, resulting in the potential to significantly reduce input costs.
With the two consecutive dry seasons in 2021 and 2022, there is likely a considerable amount of unused nitrogen left in the soil, which could be used for the 2023 crop. With the higher fertilizer prices, such fertility adjustments for next crop can be profitable as well as environment friendly. So, it is recommended to test your soil and account for all sources of nutrients for the next crop.
University of Nebraska-Lincoln (UNL) has changed recommendations for crediting nitrogen following manure applications for field crops. New research has shown that most manures are similar changing the organic-nitrogen availability factors.
With the recent increase in fertilizer prices, it is more important than ever to use the right amount of fertilizer to maximize the economic returns. Applying too little or too much fertilizer can result in substantial economic loss.
This FREE event on 4Rs of Nutrient Stewardship features knowledge and tools to improve nutrient management, soil health, crop yields and water quality. This is a great opportunity to learn about 4Rs strategies to improve crop yield and profits while protecting the environment.

Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?
Managing manure for economic and environmental benefit is based, in part, upon our ability to efficiently recycle manure nitrogen (N) between animals and crops. This article introduces University of Nebraska-Lincoln (UNL) proposed changes in recommendations for crediting manure nitrogen in a crop’s fertility program.
