From a recent half-day tour of the research facility, we’ve picked some of the most intriguing and thought-provoking points recently revealed on the farm.
Beck, who recently had hip replacement surgery, assures us he will be back “on his own two feet” when he presents to the 18th annual National No-Tillage Conference crowd in Des Moines next January.
