Abstract

No-tillage corn production has become very popular in Kentucky because of the advantages it offers producers. Currently, over half of the corn in Kentucky is planted by this method and even a higher percentage is no-till planted on erodible lands. Because of this, many fields have received little tillage in the last 10 to 20 years. Many producers wonder if soil compaction increases with time on these long-term no-tilled fields due to annual trafficking by heavy equipment. Subsoiling implements have become available that allow subsurface tillage while preserving the surface mulch layer. This practice allows for continued no-till planting while introducing some tillage into the cropping rotation. Some producers are subsoiling every second fall after soybean harvest in a corn-wheat-soybean rotation.
