Maine SARE Farmer Grant Projects

Bio: Dr. Mallory received her B.S. (1987) from Swarthmore College, M.S. (1994) from the University of Wisconsin, and Ph.D. (2007) from the University of Maine. She joined the faculty in 2008 and is Extension Sustainable Agriculture Specialist and Assistant Professor of Sustainable Agriculture.

Current Research and Extension Program

Sustainable Soil and Crop Management:  I am interested in the use of organic amendments, such as manure and compost, to supply crop nutrients and improve soil health and productivity. My recent research in a collaborative interdisciplinary field study showed that an amended soil management system that enhanced soil quality increased both long-term potato yields and the stability of those yields. Further work investigated how improved soil quality affects short- and long-term nitrogen dynamics.  New research in this area investigates the effects of compost amendment on soil quality, nutrient dynamics, and productivity in organic low-bush blueberry systems.

Local Bread Wheat Project:  A major component of my current research (and extension) program is a project that I am leading to build farmers’ capacity to produce high quality bread wheat for local markets.  Our group of 10 researchers and extension educators from University of Maine, University of Vermont, and the USDA-ARS are partnering with local farmers, millers and bakers to identify the best varieties for the region, develop fertility strategies for high-quality grain, and evaluate innovative weed management systems.  We also are developing tools to help farmers evaluate the profitability and risk of growing bread wheat and will produce a region-specific bread wheat production guide.  Click here for Local Bread Wheat Project website.
