Abstract

The primary objective of this study was to evaluate the impact of various cropping and nutrient management systems on drainage water quality and crop yields. Treatment comparisons evaluate the impact of liquid swine manure application timing, nitrification inhibitor with late fall swine manure application, cereal rye cover crop, and gypsum application. This information can be used to develop appropriate manure and nutrient management practices to minimize water contamination potential, and enhance the use of swine manure as a nutrient resource.
