Tillage systems and crop rotation significantly affect soil productivity and quality in the long-term by affecting soil carbon and the soil physical, biological, and chemical properties. Additionally, tillage systems and crop rotations control weed and soilborne diseases. There is need for a well-defined, long-term tillage and crop rotation study 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.
