An assistantship for a Masters student is available for 2010/2011 and 2011/2012 at The Pennsylvania State University to study sustainable cropping systems based on ecological principles with special emphasis on mycorrhizal fungi. The degree can be awarded in either Horticulture or Ecology, and the student will have the opportunity to interact with a diversity of researchers, a postdoc, and other graduate students in Horticulture, Crop and Soil Sciences, Entomology, The Rodale Institute, and the US Department of Agriculture. Cropping-system practices are being designed to minimize pest populations, conserve nutrients, soil, energy, and off-farm inputs.
