Tillage systems and crop rotation have a significant, long-term effect on soil productivity and the soil quality components of soil carbon and other soil physical, biological, and chemical properties. Additionally, soil tillage and crop rotation control weed and soilborne diseases. There is need for a well-defined, long-term tillage and crop rotation study across the different soils and climate conditions in the state. The objective of this study was to evaluate the long-term effects of different tillage systems and crop rotation on soil productivity and quality.
