Bio: Dr. Gallandt received his B.S. (1986) from Michigan State and M.S. (1988) from Montana State University. He received his Ph.D. from the University of Wisconson in 1994. He joined the faculty in 2000 and is an Associate Professor of Weed Ecology.
Teaching: PSE105 Principles of Sustainable Agriculture; PSE203 Weed Biology and Identification; PSE403 Weed Ecology and Management
Current Research: My research program focuses on the dynamics and management of annual weeds in organic farming systems. Current research projects include evaluation and comparison of seed-, seedling-, and mulch-based management strategies in organic vegetables. We also continue to evaluate physical weed control, aiming to improve understanding of the sources of variability in cultivation-based seedling mortality. In a collaborative project with colleagues at the University of New Hampshire and University of Vermont, we are characterizing weed communities across northern New England to better understand likely responses to changing climate. Lastly, a new series of field experiments, motivated by questions from Maine farmers, is studying soil solarization as a weed management practice.
