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 Associate 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. Recent work evaluated organic nitrogen sources for small grain production and investigated compost amendment effects on soil quality, nutrient dynamics, and productivity in organic low-bush blueberry systems.

Local Grains:  My major research (and extension) program focuses on helping establish and expand the local food and feed grain sector in New England. Recent successes in building local production, processing, and use of bread wheat have inspired and enabled new markets for other food grains (e.g., spelt, barley, rye, oats) and end uses (e.g., malt, spirits). Concurrently, the need for locally grown organic and non-GMO feed grains has continued to increase among New England’s organic dairy, chicken, and other livestock producers. In partnership with farmers, end-users, and other researchers around the region, I conduct research trials and educational programming to address key production issues and develop the local grain networks.
