As the harvest season is getting close, there are a few things we need to keep in mind this fall with regard to soil conservation concerns. Soil conditions are dry across the state. If they continue, it can be advantageous during harvest by reducing potential soil compaction. So, if the rationale for tillage is to reduce soil compaction, it is not valid. Therefore, 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. Those changes in soil condition with tillage during rain events after harvest can also reduce soil profile recharge due to increased surface run off.
