Tillage system and crop rotation have significant long-term effects on soil health, productivity, and the soil quality components of soil carbon and other soil physical, biological, and chemical properties of the soil. 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 soil types and climate conditions in the state. The objective of this study was to evaluate the long-term effects of five tillage systems and crop rotations on soil productivity and quality.
