Specialty: Soil Management
The overall research focus concerns the long-term consequences of tillage practices and cropping systems on soil chemical, physical, and biological properties and their relationship to crop growth and development. Research efforts have emphasized a multi-disciplinary approach in order to assess some of the inherent soil-plant-water relationships associated with these systems.
Current research areas include nutrient cycling in cover crop based production systems; soil quality indices as influenced by tillage/cropping system; and nutrient dynamics in organic production.
