After more than two decades of agricultural surpluses and Federal supply management programs, strong demand for food products in 1973 resulted in suspension of the Federal land set-aside programs. By 1974, virtually all acreage formerly diverted had been released and most good quality, readily usable acreage was brought back into production. This study summarizes recent changes in cropland use and evaluates additional land, mainly pasture and forest, that could be converted to crop production. But several factors will likely retard the rate of development of new land. These include size of tract, ownership patterns, ease and scale of development, crop alternatives, and competition from other uses. Existing and potential cropland are discussed within a regional context.
