Northwest and Allee Research and Demonstration Farm
Tillage systems and crop rotations have significant long-term impact on soil quality components such as soil carbon,soil physical, biological, and chemical properties, and on soil productivity. Furthermore, tillage and crop rotation influence weed and soil disease control. 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.
