McNay Research and Demonstration Farm
Tillage systems and crop rotation have a significant long-term effect on soil productivity and the quality components of soil carbon and soil biological, physical, and chemical properties. Additionally, both soil tillage and crop rotation control weed and soilborne diseases. There is a need for a welldefined, 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.
