Responsibilities

Research efforts include independent and collaborative applied research in soil fertility and management with emphasis on research related to bioenergy crop production throughout NC, but also relative to crops currently grown and crops of potential production in the Mountain and western Piedmont regions of NC. The primary objective of my research program is to improve our understanding of the role of soil fertility and management on crop production and plant growth characteristics – primarily the management of nitrogen, phosphorus, and micronutrients for the establishment and sustainability of crops in a profitable and environmentally sound manner.
