Speaker Biographies

Dr. Jochum Wiersma has been the small grains extension specialist at the University of Minnesota for the past 30 years. In that time, he focused his research on ways to maximize grain yield and minimize the cost of production per bushel. Past work has included work on seeding rates, the use of fungicide to combat FHB and control diseases, and the use of foliar nitrogen to improve grain protein content.  More recently, he has explored the concept of yield gaps and whether it makes economic sense to close the gap between actual and attainable grain yield.
