This report contains an examination of the potential of the US Department of Agriculture's Conservation Security Program to help induce farmers in the Western Corn Belt to shift to more ecologically diverse crop rotation systems. The report is a complement to a Selected Paper presented by the same authors at the 2005 American Agricultural Economics Association annual meetings. The present report contains more detail on research methods and data than was possible to include in the AAEA paper. The region focused on is a six-county area of southeastern South Dakota.
