Tillage systems and crop rotation affect soil productivity and quality in the long-term by affecting the soil quality components of soil carbon and soil physical, biological, and chemical properties. Tillage and crop rotations contribute to weed and soil disease control. There is a need for well-defined long-term tillage and crop rotation studies across the different soils types 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 quality and productivity.
