The Corn Belt is a region of the Midwestern United States where corn (maize) has, since the 1850s, been the predominant crop, replacing the native tall grasses. By 1950, 99% of the corn was grown from hybrids. Most corn is fed to livestock, especially hogs and poultry. In recent decades soybeans have grown in importance. The U.S. produces 40% of the world crop.
