For centuries, farmers have used crop rotations to diversify crop production. During the last 30 years, most crop rotations have been eliminated as part of the shift toward enterprise specialization. Chemical inputs, improved hybrids and varieties and large field machinery have increased productivity and pushed the production of the major commodity crops with ever fewer farmers. The continued shift toward less diverse and industrialized farming is considered by many experts to be inevitable, as well as essential to support a growing world population on a diminishing agricultural land base (Urban, 1991).
