Did Strip-Till Solve My Nutrient Stratification Problems?

Independent on-farm researcher Marion Calmer checks in from Alpha, Ill., with a preview of his 2024 National Strip-Tillage Conference presentation, “Did Strip-Till Solve My Nutrient Stratification Problems?” Over the last 5 years, Calmer has been examining fertility levels vertically in his soil profile. This inch-by-inch examination uncovered a serious nutrient stratification problem on his farm that was costing him up to $135,000 annually.
