Extension:
National leader in comprehensive nutrient management planning.
Primary contact for the land application of livestock manures and industrial/municipal biosolids in Indiana.
Research Areas:Evaluate how sourcewater, drainage, P source rate and placement, and animal diet manipulations impact P loss from soil to water.
Work with animal scientists to determine how diet manipulations impact the excretion of specific manure P compounds and how these compounds are sorbed by soil. Work with plant physiologists to determine the physiological and molecular response(s) of plants to N, P and K nutrition. Improve soil test methods for plant nutrients.
