Crops and Soils
Tillage systems and crop rotation affect soil health, productivity, and quality in the long-term by affecting soil carbon and other physical, biological, and chemical properties of the soil. Furthermore, 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 five tillage treatments and three crop rotation systems on soil quality and productivity.
