RECENT YEARS have witnessed the introduction of a flood of
new techniques in farming. Technological developments include
mechanization and the increased use of mechanical power in both
crop and livestock production. They also include revolutionary
changes in breeding, feeding, disease control, and other contributions
of the biological sciences. A striking effect of these new techniques
has been to increase the productivity of human labor and
thereby the size of unit a farmer can handle. With this has come
increased size of farm units and greater specialization within the
farm business. Farmers are concentrating on fewer enterprises in
order to distribute the cost of expensive equipment involved in
these new techniques over more units of business. This concentration
on fewer crops or fewer classes of livestock enables farmers
to keep up more effectively with the new techniques that are
en.tering the picture.
