This study projects resource requirements for United States agriculture under alternative farm programs and various levels of export demand in 1980. Cropland, man-hours of labor, and capital required to produce each level of output are projected for a farm economy ranging from a free market with no controls on crop production to strict controls on all major crops through acreage quotas. Resource requirements are estimated by first allocating crop production among the various regions o f the United States in a manner to minimize total costs of producing and transporting grain and oilseed crops to the final point of consumption. After acreages of each crop are established for each farm program and export level, man-hours of labor are estimated for crop and livestock production. Capital requirements also are partly based on the location of crop production, but other variables are also included in the estimating equations.
