CORN BELT is the uniquely fertile region of the "prairie triangle" in the upper Mississippi Valley, stretching from Ohio to Nebraska, in which farmers since the mid-nineteenth century have specialized in the corn crop. In 2002, Iowa, Illinois, Indiana, and Ohio together were responsible for almost half of American corn production. Corn-belt farming emphasizes a judicious combination of producing corn both for the market and for fattening swine and beef steers. Since 1960, soybeans have rivaled corn as the leading cash crop. Cultivating domestic grasses and small grains such as oats and winter wheat and dairying are other important agricultural activities in the corn belt.
