Professional Interests: Biologically based soil fertility; soil health; field crops; organic production

Teaching: Cooperative Extension

Research:  My research focuses on how to manage biologically based fertility systems to supply crop nutrient needs and improve soil health and productivity. Prior work evaluated organic fertility strategies for bread wheat yield and quality, compost as a fertility source for lowbush blueberry, and soil amendment impacts on soil carbon and nitrogen dynamics, soil quality, and potato yield stability. My current research (and extension) program aims to help farmers and end-users expand the local food, beverage, and feed grain sector in New England. Projects include green manure management, weed management, variety evaluations for small grains, pulses, and oilseeds, and crop modeling.
