The following is from Environmental Compliance in U.S. Agricultural Policy: Past Performance and Future Potential, by Roger Claassen, Vince Breneman, Shawn Bucholtz, Andrea Cattaneo, Robert Johansson, and Mitch Morehart, AER-832, USDA/ERS, June 2004.
Since its inception in the 1930s, U.S. agricultural policy has been designed to support farmers' incomes while promoting soil conservation practices. By the 1970s, however, policymakers recognized that existing farm price and income support programs were not always consistent with soil conservation efforts. An unintended effect of these programs was to encourage producers to maintain or expand production of relatively erosive crops, such as row crops (corn, cotton, soybeans) , sometimes on highly erosion-prone soils. At the same time, the Government was helping farmers reduce soil erosion and related damages through conservation cost-sharing programs. Policymakers further recognized-aside from concerns about consistency-that farm program payments could be used as incentives to encourage better conservation behavior.
