- Ph.D. Phosphorus behavior in heavily fertilized European Soils, Aberdeen University, 1996
Professional Activities and Interests
- My research and extension activities revolve around improving the efficiency of manure nutrient management , using innovative approaches to protect the environment and enhance the profitability and sustainability of farming systems.
Current Projects
- Integrated, Innovative Cropping Practices to Reduce Nitrogen, Phosphorus and Sediment Losses in the Shenandoah River Watershed
- Utilizing conservation tillage to minimize nutrient losses from poultry litter applied in grain production systems in Virginia
- Coordinating Regional Efforts Involving Manure Management in Reduced Tillage and Pasture Systems
- Alternate uses for Poultry Litter in the Shenandoah Valley of Virginia
Current Extension Programs
- Nutrient management training and certification for Virginia and mid-Atlantic region
- Beneficial recycling of poultry litter nutrients in low input forage systems
- Using manure injection to improve nutrient utilization and reduce losses from reduced tillage and pasture systems
