Abstract
The primary design ofthis project isto determine the impact of appropriate rates of swine manure applications to corn and soybeans based on nitrogen and phosphorus requirements, crop yields, soil phosphorus accumulation, and nitrate and phosphorus leaching to groundwater. Another purpose of this design is to develop and recommend appropriate manure and nutrient management practices to producers to minimize the water contamination potential and enhance the use of swine manure as an organic fertilizer. A third component is to determine the potential effects of rye as a cover crop to reduce nitrate loss to shallow ground water.
