McNay Research and Demonstration Farm
Tillage and crop rotation systems have significant long-term effects on soil quality and productivity including the soil quality components of soil carbon and soil biological, physical, and chemical properties. Additionally, both soil tillage and crop rotation have impacts on weed and soil disease control. There is need for well-defined, longterm tillage and crop rotation studies across the different soils 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
