Our latest Ask the Operator question asks for advice on planting cover crops after wheat harvest.

With 35 years’ experience working for the University of Wisconsin Extension, research is second nature for Sparta, Wis., no-tiller Jim Leverich. Now retired, he maintains a rigorous program of testing to get the best yields he can on his 1,000-acre corn-soybean operation that his forbears began as a 25-acre orchard in 1864. In testing components of the “4Rs” of nutrient management, he’s found anhydrous ammonia consistently provides the most efficient source of nitrogen (N) while offering the highest level of safety for the environment.

Our latest edition of Ask the Operator resolves something of a cliffhanger from the beginning of the Fellowship Program. Jim Leverich had said he planned to potentially use a biological product for yields this year.
