Income opportunities from full-time farming in South Central Iowa

“…Irwin (34), in a linear programming study of lôO-acre farms in southern Iowa, considered the effects of intensive pork production systems upon the allocation of farm resources and farm income. Since acreage was considered fixed, the farm business had to be expanded in an intensive manner, i.e., more' capital or a different technology was combined with a fixed amount of land.…”
