Book Description
The demand for food is expected to rise due to increases in world populations over the next decades. The use of heavy machinery to meet this demand for food is expected to increase as well. Additionally, soil compaction is recognized as a major concern in agriculture dependent on the use of heavy machinery. Soil compaction has been shown to negatively impact crop production, which may occur because of overuse of heavy machinery used in tillage operations, sowing, harvesting, and manure and fertilizer applications. Soil compaction also affects physical, chemical and biological processes occurring in the soil including the mineralization of soil organic carbon and nitrogen. Long-term experiments that include tillage and crop rotations are necessary to understand the impact of soil management practices on soil properties. Tillage practices (conventional tillage-CT; minimum tillage, MT; and no tillage, NT) and crop rotations (continuous corn-CC and corn-soybean-CS) effects on soil compaction and carbon and nitrogen were studied in the long-term Triplett-Van Doren plots which are part of the Ohio Agricultural Research Development Center (OARDC). These plots are experimental sites located in northeast Ohio (Wooster) and northwest Ohio (Hoytville).
