From the perspective of the accredited certification agency and the farmer, Farm A consists of 9 fields which range from 25 to 93 ha in size for a total of 484 cropped hectares, Farm B consists of 13 fields which range from 4 to 16 ha in size for a total of 129 cropped hectares, and Farm C consists of 1 field of 0.5 ha. The two larger farms grows primarily corn, soybean, small grain and alfalfa as cash crops, whereas the smaller farm grows a large number of vegetable crops. In evaluating the crops grown on these different fields over the past five years we realize that there is no distinct pattern of crop rotation common among the 9 fields of Farm A, the 13 fields of Farm B, or within the one field of Farm C.
It is difficult to easily describe ‘the rotation’ each of the three case study farms employs. Each uses a multitude of rotations based on the site specific nature of the fields within the farms.
