Andrew Klopfenstein, Senior Research Associate Engineer, is a 2-time graduate of The Ohio State University with both his Master’s and Bachelor’s Degrees in Agricultural Engineering. Andrew has been at Ohio State for ten years. He is originally from a family farm in Northwest Ohio in Paulding County that grows corn and soybeans and custom harvests forage crops for several dairies. He currently completes research in the areas of compaction, multi-hybrid corn, multi-variety soybeans, late season application of nitrogen, unmanned aerial systems, autonomous vehicles, and big data. He has spent numerous years working on planters and evaluating planter technology. Another area of interest is compaction, in which Andrew continues to work with ways to quantify and model the effects while looking at large axle loads from equipment and pinch row effects from planters. Andrew manages all field operations, labor, proposals, and projects for Dr. Scott Shearer in these research areas and teach classes in the department of Food, Agricultural and Biological Engineering.
