The Corn Belt is a region of the Midwestern United States that, since the 1850s, has dominated corn production in the United States. More generally, the concept of the "Corn Belt" connotes the area of the Midwest dominated by farming and agriculture.  
There is lack of consensus regarding the constituents of the Corn Belt, although it often includes: Iowa, Illinois, Indiana, southern Michigan, western Ohio, eastern Nebraska, eastern Kansas, southern Minnesota, and parts of Missouri.  It also sometimes includes: South Dakota, North Dakota, all of Ohio, Wisconsin, all of Michigan, and Kentucky. 
The region is characterized by level land, deep fertile soils, and a high organic soil concentration. 
As of 2008, the top four corn-producing states were Iowa, Illinois, Nebraska, and Minnesota, accounting for more than half of the corn growth in the United States. 
On account of new agricultural technology developments between 1860 and 1970, the Corn Belt went from producing mixed crops and livestock into becoming an area focused strictly on wheat-cash planting. After 1970, increased crop and meat production required an export outlet, but global recession and a strong dollar reduced exports and created serious problems even for the best farm managers. 
Most corn grown today 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. 
By 1950, 99% of corn has been grown from hybrids.
In 1997, the USEPA published its report on United States' ecoregions, in part based on "land use". Its "Level III" region classification contains three contiguous "Corn Belt" regions, Western (47), Central (54), and Eastern (55), stretching from Indiana to eastern Nebraska.
