Impediments to agricultural change extend beyond lack of appropriate research and the federal farm program to addiction to use of agricultural chemicals. Several recent trends in American agriculture have been caused by or have resulted in dependence on agricultural chemicals. They include the continuing separation of livestock from farms, farm size, separation of ownership and farming of the land, discontinuity of learned procedures, part-time farming, and certain aspects of noxious perennial weeds. This implies that prospects for agricultural change are related to the trends with which they are associated.
