Land Application

With increasing regulations, the livestock producer needs to understand the scientific principles that affect manure transformations and how to use these principles to manage the manure for maximum fertilizer value with minimal environmental impact. Improved land application of manure is one part of the solution, but we suggest that the producer evaluate the quantity of nutrients arriving on the farm as feed, animals, and fertilizer compared to the total that is exported.

Proposed Changes to Nebraska Recommendations for Manure Nitrogen Credit

This article introduces University of Nebraska-Lincoln (UNL) proposed changes in recommendations for crediting manure nitrogen in a crop’s fertility program.
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.

Manure Nitrogen Use for Increased Profit and Environmental Protection

For many years, the University has used a recommended equivalence of 47% available over the course of 3 years for feedlot manure, 37% for compost, and 52% available for poultry manure with litter. Recent research shows that these numbers may be a little low, but they are intentionally conservative so as not to limit yield due to nitrogen deficiency.

Poultry Litter’s Agronomic and Natural Resource Benefits

Soils and data scientists reviewed the results from 90 research studies and 866 field observations comparing poultry litter with inorganic fertilizer. Their findings provide several important insights to consider when using broiler litter in Nebraska. This article will attempt to answer: What is poultry litter’s nutrient value? Is there a yield benefit from poultry litter? Which soils benefit most from poultry litter? Is there value from sustained poultry litter use?

Many Nebraska farmers are experienced with using beef feedlot and swine manures as fertility products. Over the next few years, Nebraska crop farmers may have opportunities to consider using broiler poultry litter as a soil amendment and fertilizer. Other regions of the US have a history of using poultry litter in crop production from which we can take away a few lessons.
