Biography:

Julie Grossman is an Associate Professor in Biological and Sustainable Horticulture in the Department of Horticultural Science at the University of Minnesota. Prior to her return to the University of Minnesota in 2014, Dr. Grossman spent 7 years as faculty in the Department of Soil Science at NC State University, working in soil fertility management of organic farming systems. She holds an M.S. in Soil Science and Ph.D. in Agronomy and Plant Genetics from the University of Minnesota, and was an NSF Post-doctoral Fellow at Cornell University.
Julie’s research broadly explores the ways in which we can better manage plant-soil-microbe relationships in order to enhance soil fertility through microbial processes, with the ultimate goal of developing sustainable food production systems. A central thread that connects much of our work is the examination of winter annual legume cover crops to help maintain landscape diversity and tighten nutrient cycling in agroecosystems.
Julie has a strong interest in soil science and sustainable agriculture education, and is former Chair of the Sustainable Agriculture Education Association, a national organization supporting the development, application, research, and exchange of best teaching and learning practices in sustainable agriculture. At the University of Minnesota she teaches the service-learning based capstone course for a new undergraduate Food System major, as well as a course focusing on farm and soil management, using the student organic farm as a living laboratory.

Research Areas:

  • Soil science
  • Organic agriculture
  • Cover crops
  • Legumes
  • Biological nitrogen fixation
  • Rhizobia

Current N-related Projects:

  • A multi-regional approach for sustained soil health in organic high tunnels: nutrient management, economics, and educational programming;
  • Summer Cover-Cropping Strategies and Organic Vegetable Production for Beginning, Immigrant Farmers;
  • Optimizing soil health in season extension environments through innovative cover crop management;
  • Bringing the benefits of legume cover cropping to northern Midwest climates
