EXTENSION AND RESEARCH EMPHASIS

Nutrient and water quality impacts from row crop production systems. Focus is specifically on nitrogen and phosphorus management effects on crop yield and water quality at edge of field.
Conduct applied research applicable to corn, soybean, wheat and forage producers. Work directly with agricultural producers, associated support industries and OSUE staff on agronomic management and cropping systems. Develop outreach materials for these audiences.
