Henry A. Wallace Endowed for Sustainable Agriculture
Research Interests: Agricultural ecology, especially cropping system diversification, conservation practices, and weed ecology and management.
Brief description of current research:
Matt Liebman's research focuses on the development of farming systems that are productive, profitable, and healthy for people and the environment. Topics addressed in Dr. Liebman's research group include: (1) biomass production and nutrient cycling by annual and perennial crops used as biofuel feedstocks; (2) weed suppression by cover crops, rodent and insect seed predators, and diverse crop rotations; (3) energetic costs and economic returns associated with simple and diverse rotation systems; and (4) dynamics of native plant communities in filter and buffer strips constructed in and around corn and soybean fields.
