2021 and 2022 Drainage Water Quality Impacts of Agricultural Management Practices

Authors: , , , , , , ,

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 assess the effects 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.
