Animal Manure Management

Recycling local manure nutrients before purchasing fertilizer is key to protecting the environment. Manure can be an economic “Win”, due to its fertility value, and a soil quality “Win”, due to its organic matter.  But it can also be a community risk, due to odors and pathogens. Our live educational programs, online courses, and resources provide science-based information on economically viable, environmentally sound manure handling systems that also comply with all regulations.

Manure Impact on Erosion and Runoff

This article reviews the value that results from changes to soil’s physical characteristics. Charles Wortmann and Dan Walters, faculty with the University of Nebraska-Lincoln monitored soil erosion, runoff, and phosphorus (P) loss from replicated field plots over three cropping seasons immediately after manure application and four subsequent years when no manure was applied. Significant erosion and runoff benefits were observed for sites receiving animal manures.

Manure Impact on Soil Aggregation

Manure increases formation of larger and more stable soil aggregates. Several benefits result for fields fertilized by manure compared to commercial fertilizer including reduced runoff and soil erosion and increased water infiltration leading to greater drought tolerance.

Is Manure a Fertility Option for Wheat?

With ground opening up for manure application following wheat harvest, this is a good time to ask about the fit for manure with wheat? There are some good opportunities to use manure following wheat harvest.

Siting Animal Facilities to Reduce Neighbor Nuisance

Wind direction and speed affect dust and odor risk. A first step in assessing and minimizing potential dust and odor nuisance risk of a livestock operation is identifying the most likely downwind directions. This article will share wind frequency data for 44 Nebraska locations to consider siting options for reducing these nuisances.

Manure and Soil Health Presentations Bring Experts, Give Voice to Wondering Minds

Farmers and ranchers are becoming increasingly aware of the importance of soil quality/health to the productivity and sustainability of their agricultural system. Research and field observations have demonstrated that carefully managed manure applications can contribute to improved soil quality with limited environmental and social risks. However, a comprehensive assemblage of outputs and conclusions from research studies, field trials, soil labs databases, and other sources has never been developed.
