Responsibilities include managing coordinating research programs for the laboratory which has the mission to develop technologies and strategies for managing soils that increase adoption of sustainable production/cropping systems, particularly conservation systems that reduce economic risk and farm production costs; improving soil quality and productivity; and relating agriculture to global change. Specific research focuses on improving methods for waste application to maximize plant nutrient use efficiencies, while minimizing pollution potential. Other important objectives of the research program are to develop conservation systems that reduce drought risk of cash crops, develop environmentally sound waste management systems, and determine the effects of atmospheric CO2 levels on above- and belowground processes that affect crop production, soil carbon storage and trace gas emissions.
