This issue paper outlines the technologies and approaches that poultry and livestock producers can use to decrease the amounts of nitrogen and phosphorus entering the environment. This study focuses on two nutrients and addresses two environmental concerns: volatilization and manure nutrient distribution. Decreasing the nitrogen and phosphorus excreted by poultry, swine, or cattle can minimize these concerns. Chair: Terry Klopfenstein, Department of Animal Science, University of Nebraska, Lincoln.
