Dr. Edwin Winzeler received a bachelor's degree in Natural Resources and Environmental Sciences from the University of Illinois and a M.S. and PhD from Purdue University in Soil Science, Agronomy. As an undergraduate he studied soil variability and fertility of the 140+ year-old Morrow Plots at the University of Illinois research farm. His PhD involved the development of a mapping application of the soil climate classification system of the USDA to examine soil climate changes over time. Dr. Winzeler also conducted research on soil potassium availability in a suite of agricultural soils in southern Indiana. Additionally, he helped in the development of soil mapping tools for the Terrain Attribute Soil Mapping (TASM) effort of the USDA. Prior to joining the Dale Bumpers Small Farms Research Center, he worked for Pennsylvania State University at the Fruit Research Extension Center on problems in fruit tree horticulture and entomology. His research interests involve the use of geographical information systems (GIS) to model the variability of agricultural systems, with particular emphasis on soil moisture, terrain indices, and the development of dynamic soil information systems within artificial intelligence (AI) frameworks. Through his research Dr. Winzeler aims to increase the performance efficiency of small farms with limited resources by incorporating geospatial tools and AI in day-to-day operations.
