This is the time of the year when tillage becomes the number one priority for some, whether they need it or not. The question to ask is, “Do I need to till this fall?” Given the economic and environmental challenges farmers are facing, the answer in most cases is no. With the end of the growing season here and harvest under way, now is a good time to start thinking about this decision. Take into consideration your site-specific condition and whether tillage makes economic and environmental sense given the input costs associated with tillage operations as well as the impact on soil and water quality. Even though tillage may be needed in certain situations and field conditions, a well-managed field and proper crop rotation may not call for tillage.
