McNay Research and Demonstration Farm
Tillage systems and crop rotation systems have significant long-term effects on soil health and productivity and the soil quality components of soil carbon and other physical, chemical, and biological properties of the soil. Furthermore, soil tillage and crop rotation control weed and soilborne diseases. There is need for a well-defined, 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 long-term effects of different tillage systems and crop rotations on soil productivity and soil quality.
