Soil tillage increases the potential for soil erosion and reduces water infiltration and subsoil recharge. Keeping crop residue on the soil surface this fall along with cover crops can increase water infiltration, reduce soil erosion, sediment and nutrient loss, contribute to soil organic matter, and improve soil quality. Here are some things to keep in mind when planning for the choice of tillage practice this fall.

It is not to soon to start planning for crop year 2002. When the crops come out this fall, producers will again face tillage choices. The first decision is what tillage, if any, needs to be done after harvest. Because crop residue from harvest is still on top of the soil, fall is the best time to move to a no-till system. The benefits of no-till include less time in the field, lower fuel consumption, and improved soil physical and chemical properties such as infiltration rate, reduction of soil erosion, conservation of soil moisture, and improvement of organic matter and other nutrients.
