McNay Research and Demonstration Farm
Tillage systems and crop rotation have major long-term effects on soil productivity and the quality components of soil carbon and soil biological, physical, and chemical properties. Additionally, both 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 soil 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 productivity and soil quality.
