Three levels of the Total Soil Management® soil fertility program (A, E, and I) are tested against University of Illinois, Tri-State, and conventional fertilizer recommendations each year. The various levels of the program are explained in the topic "Fertilizer Budgets". The data below is for the most recent corn and soybean harvest at the Catlin farm, showing bushels per acre, followed by a chart showing the averages for the farm since its beginning.
