As we gear up for planting this week and next there are two insect pests that need to be on our radar. First, reports from Purdue, Penn State and elsewhere have noticed significant flights in black cutworm. This is a migrating moth that lays eggs in corn, which can cause severe cutting of the plant.

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.
