Professor of Sustainable Agriculture and Extension Specialist
Degree: Ph. D. 2007, University of Maine
Location: 495 College Avenue, Orono
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 in three main areas: producing small grain, pulse, and oilseed crops for food and beverage markets; enhancing soil health; and adapting to a changing climate. Projects include cover crop and green manure management, weed management, variety evaluations, and crop modeling.
