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. The No-Till Legend switched back to strip-till in 2023 for the first time since 1995 in an effort to solve his nutrient stratification problems.
