This article appeared in the most recent Integrated Crop Management (ICM) News, written by Mahdi Al-Kaisi. He is an ISU agronomy professor and former Iowa Learning Farms faculty adviser. He cites several good reasons to temper tillage this fall in order to improve soil health.
Al-Kaisi says, “Pay attention to tillage intensity after harvest; tillage affects soil conditions and destroys soil structure, which can create significant problems. Tillage accelerates organic matter loss, which results in more problems of accelerating soil erosion and surface runoff.”
