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.

Valuing Manure as a Seller or a Buyer

When talking about manure's value, one needs to think about a variety of factors. Most folks think of fertilizer nutrients as manure’s primary value or MVP, but it takes more than one or two star players to make a great team. As such, manure wouldn't be as great as it is without other characteristics like the added organic matter that you get when applying manure, or the microbial community that is added to your field with that application.

“Applying Manure Management Concepts On-Farm” Programs in February and March

The Animal Manure Management team is hosting “Applying Manure Management Concepts On-Farm” programs across the state. They begin on February 8th in Lexington and continue throughout February and into March. While these events have traditionally been targeted at livestock operations that are required to attend as part of their permit, the team has made huge progress the last several years in making the information in those programs very interactive and applied for anyone that uses manure. I encourage all crop farmers that use or are considering using manure to plan on attending. At the programs, you’ll discover how to determine which fields are the most economical for manure use and which fields can benefit the most from manure’s ability to improve soil health and water quality.

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

By incorporating residual nitrate-nitrogen into the nitrogen fertilizer prescription, there is potential to substantially reduce fertilizer cost per acre.
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.

The science behind 50-degree soil and nitrogen application

Does nitrogen becoming nitrate mean we are going to lose it? No, it takes rainfall or snowmelt in the spring that will cause a leaching event, but it does increase the risk of loss. Certainly, there is a balance between making sure we get our manure applied before the soil freezes and applying too early, but hopefully the information above illustrates a bit behind the science of the 50°F and cooling recommendation.
