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.

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.
