Northwest and Allee Research and Demonstration Farms
Crops and Soils
Tillage system and crop rotation systems have significant long-term effects on soil health, productivity and quality, soil carbon, and other soil physical, biological, and chemical properties. Furthermore, tillage and crop rotation control weed and soil borne diseases. There is 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 five tillage systems and crop rotations on soil productivity and quality.
