Sugar beets have been grown in the Red River Valley since the 1920s. In August 1972, some 300 farmers living in some seven North Dakota and Minnesota counties formed a cooperative. This cooperative, subsequently incorporated as the Minn-Dak Farmers Cooperative, allowed the members to diversify their farming operations by adding sugar beets to their crops. The Cooperative used funds provided by the members and by loans to build a sugar beet processing mill north of Wahpeton, North Dakota. The first crop of sugar beets was processed in 1974. Minn-Dak Farmers Cooperative has become a major contributor to the prosperity of this agricultural region. In 1993, the Minn-Dak Farmers Cooperative had 339 members who grew more than a million tons of sugar beets on some 66,000 acres of farmland. The Minn-Dak operation employs over 300 workers at its Wahpeton mill, and the Cooperative generates some 80-90 million dollars of revenue annually.
