This UNL research study provides insights on the rotation of annual crops with alfalfa as a highly effective means of reducing nitrate-nitrogen contamination in groundwater.

For producers planning corn-on-corn this growing season, there may be a substantial opportunity to reduce nitrogen fertilizer applications, as drought and reduced yields likely left higher-than-normal residual N in many fields.

The nearly 70 on-farm research studies conducted by Nebraska farmers in 2022 addressed fertility and soil management, cover crops, crop protection, equipment and non-traditional products, including biologicals.

Results from 2022 variety trial research conducted on numerous cover crop species at five UNL research stations across Nebraska.

“How much is this manure worth?” This is a common question from both livestock farmers who are supplying manure and crop farmers who are utilizing it. To answer this question, it is important to understand the difference between gross value and net value. The gross value of manure reflects the equivalent commercial fertilizer value of the nutrients contained in the manure. The net value considers the impacts of application method, transportation, and cropping system nutrient needs as well as intrinsic values that are much more difficult to put a number on. Therefore, this article will focus on determining the gross value of nutrients in manure.
