Solving Vertical Destratification for Higher Corn Yields
Over the last 5 years, No-Till Legend, No-Till Innovator and longtime independent on-farm researcher Marion Calmer has been examining fertility levels vertically in the soil profile on his Alpha, Ill., farm. This inch-by-inch examination uncovered a serious nutrient stratification problem on his farm. In this eye-opening session that puts no filter on the findings of his independent research, he examines the time and place for each system and gives you a new perspective on phosphorus and potassium application. Calmer is a 4-time recipient of the conference’s Best Presentation Award.
