McNay Research and Demonstration Farm
Tillage system and crop rotation have a significant long-term effect on soil productivity and soil quality components such as soil carbon and other soil physical, biological, and chemical properties. In addition, both tillage and crop rotation have affects on weed and soil disease control. There is a definite need for well-defined, long-term tillage and crop rotation studies across the different soils and climatic conditions in the state. The objective of this study is to evaluate the long-term effects of different tillage systems and crop rotations on soil productivity.
