Dr. Tony J. Vyn is a Professor and Cropping Systems Extension Agronomist in the Department of Agronomy at Purdue University. Tony grew up on a hog and cash crop farm near Chatham in Southwestern Ontario, Canada. He earned his degrees from the University of Guelph, (in Guelph, Ontario) and was a faculty member in the Crop Science Department at the same university from 1987 until he left for Purdue University in 1998. Dr. Vyn advises several graduate students in research focused on understanding the interactions of tillage, crop rotation, and nutrient placement systems with soil properties and crop response. His current investigations include tillage comparisons (like no-till versus strip tillage), RTK automatic guidance for strip tillage and nutrient banding, soil carbon sequestration, plant-to-plant variability in corn, stacked trait influences on optimum plant densities and N management for corn in high yield situations, corn and soybean response to micronutrient applications, and soybean root disease response to tillage, rotation and prior fumigation. He has served as Extension Coordinator for the Agronomy Department at Purdue and as Associate Editor for Agronomy Journal, Crop Science and Soil and Tillage Research. In his spare time, he particularly enjoyed cash-crop farming with his own family from 1980 to 1998.
