The region is characterized by level land, deep fertile soils, and a high organic soil concentration.[6]
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.[7]
More recently, the USA corn belt was mapped at the county level using the Land use and Agricultural Management Practices web-Service (LAMPS),[8] along with animated maps of changes in time (2010–2016).[9]
History
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.[3]
In 1956, former Vice President Henry A. Wallace, a pioneer of hybrid seed, declared that the Corn Belt has developed the "most productive agricultural civilization the world has ever seen".[10]
Most corn grown today is fed to livestock, especially hogs and poultry. In recent decades soybeans have grown in importance.
By 1950, 99% of corn has been grown from hybrids.
EPA Ecoregion
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.[11][12]
