Northern Research and Demonstration Farm
Tillage systems and crop rotation systems have significant long-term effects on soil productivity and the soil quality components of soil carbon and other soil physical, biological, and chemical properties. Additionally, soil tillage and crop rotation control weeds and soilborne 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 different tillage systems and crop rotations on soil productivity and quality.
