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

Recent Honors

  • Technical Editor of the Journal of Environmental Quality, January 2009 to present.
  • Associate Editor of the Journal of Environmental Quality, January 2005 to December 2008.
  • President of SERA-IEG 17 (Southern Extension and Research Activity Information Exchange Group) for 2005-2006, and current member.
  • Adjunct Assistant Professor, Department of Poultry Science, NC State University, Raleigh, NC.
  • USDA Secretary of Agriculture Honor Award-Phosphorus Loss Assessment Team 2004
