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.

Tips for Winter Manure Application

Manure application on frozen or snow-covered soil poses a higher risk of nutrient loss through runoff.

Nebraska 4Rs Nutrient Stewardship Field Day Set for July 6

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.

Using a Cornstalk Nitrate Test to Evaluate Nitrogen Management Decisions

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.

Another Dry Year: What to Know About Leftover Nitrogen in Soil Following Dry Conditions

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.

New UNL Manure Nitrogen Crediting Recommendations for Crop Fertility

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.

Now is the Time to Use the Nutrients You are Banking in Your Soils

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.

Planning 2021 Fertilizer-N Application Following a Dry 2020

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?

Proposed Changes to Nebraska Recommendations for Manure Nitrogen Credit

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.
