Abstract
This study aims to evaluate the impact of manure application timing and different ground cover strategies on drainage water quality and crop yields. Treatment comparisons evaluate the impact of fall vs spring injected liquid swine manure, spring urea ammonium-nitrate (UAN) sidedress, and three different treatments with either annual or perennial cover crops. This information can be used to develop appropriate manure and cover crop practices to minimize nutrient loss and enhance the use of swine manure as a nutrient resource.
