David's area of responsibility is Organic/Sustainable and Alternative Crop Production. His appointment is 75% research and 25% teaching. David earned his Ph.D. in Agronomy with a focus in Soil Science from the University of Georgia and his M.S. in Crop Science from North Carolina State University. His research program emphasizes sustainable management systems for specialty crop production, including non-chemical alternatives to soil fumigation, reduced-tillage organic production systems, and integration of cover crops into production systems. Current research projects also focus on developing practical organic forage production systems for the Southern region, for both organic ruminant livestock production and for integration into sod-based crop rotations for improved soil quality and crop productivity. Dr. Butler’s teaching program includes PLSC 275, Organic & Sustainable Crop Production and PLSC 415/515, Agroecology. Dr. Butler also serves as chair of the Organic Production concentration in the Plant Sciences major.
