If every product added the “2 or 3 bushels per acre” promised, every farmer would easily have 400 bushel corn or 100 bushel canola.

In this video, filmed at the recent FarmSmart conference at Guelph, Ont., Joe Lauer, professor of agronomy with the University of Wisconsin-Madison, offers his thoughts on questions to ask of companies selling crop enhancement or protection products, as well as his advice on sound first steps in trialing a new product.
