Tillage system and crop rotation have major long-term effects on soil productivity and soil quality components of soil carbon and other soil physical, biological, and chemical properties. Additionally, soil tillage and crop rotation controls weed and soil borne diseases. There is a 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 rotations on soil productivity and quality.
