Feedlot Manure Focus of SARE Project

Impacts on crop yields, nitrate levels, weed and insect populations, and microbial biomass, as well as management decisions were examined.

In 1996, Colorado State University received a grant from the USDA Sustainable Agriculture Research and Education Program (SARE) to work on feedlot manure utilization in the South Platte River Basin. This newsletter summarizes the results of this project over the last few years.
