Which States Are In The Wheat Belt? The Western Corn Belt Plains is a Level III ecoregion designated by the Environmental Protection Agency (EPA) in seven U.S. states, though predominantly in Iowa. This region’s terrain is generally level with soil rich in fertility and organic soil. The southern and southeastern border of this region is irregular and crossed by major northwest- to southeast-trending stream valleys.

After several years of low corn rootworm populations, the “billion-dollar bug” is catching eyes again in the Corn Belt. Silty, loamy, and sandy soils are formed from alluvium, though not as sandy as the Platte River Valley (27g) to the west. Most of the farms in the belt average at least 300 acres and are owned and operated by families. In 2008 alone, 19% of the total corn production in the US came from Iowa while 17% of the total soybean production also came from Iowa. Tallgrass prairie, wet meadows, and scattered riparian forests are the potential natural vegetation of the area, with forests generally denser and older than in region 27g. Most of the region has been converted from wet prairie to agricultural use with substantial surface water drainage. The greater relief and deep loess hills of the Nebraska/Kansas Loess Hills are markedly different from the flat alluvial valley of neighboring 47d. Our editors will review what you’ve submitted and determine whether to revise the article. Potential natural vegetation is tallgrass prairie with woodland in narrow valleys and stream reaches. Let us know if you have suggestions to improve this article (requires login). Loess deposits tend to be thinner than those found in 47e to the west, generally less than 25 feet in depth except along the Missouri River where deposits are thicker. The more irregular topography and erosive, silty soils contribute to a mixed land use with less cropland and more pasture and woodland than neighboring regions.
The deep silty and clayey alluvial soils support extensive cropland agriculture. Omissions? The Corn Belt area is, however, considerably diversified agriculturally, and an alternative name—feed-grains and livestock region—describes it more accurately. Despite having a consensus about what the Corn Belt is, there is a lack of one when it comes to the areas that constitute the belt. The Northwest Iowa Loess Prairies ecoregion is a gently undulating plain with a moderate to thick layer of loess. World Leaders In Corn (Maize) Production, By Country, The Largest Football (Soccer) Stadiums In The World. “Federal approval of the Corn Belt Ports is great news for our rural communities in central and west-central Illinois.

The Lower Platte Alluvial Plain is an extension of the broad Platte River Valley (27g) to the west; however, this region is within the Western Corn Belt Plains and contains a combination of vegetation, soils, and climate more similar to other areas in 47.
Soils are deep, fertile, and rich in organic material and nitrogen, and the land is … The Iowan Surface ecoregion is a geologically complex region located between the bedrock-dominated landforms of the Paleozic Plateau/Coulee Section (52b) and the relatively recent glacial drift landforms of the Des Moines Lobe (47b). Corn Belt, traditional area in the midwestern United States, roughly covering western Indiana, Illinois, Iowa, Missouri, eastern Nebraska, and eastern Kansas, in which corn (maize) and soybeans are the dominant crops. Loess deposits are generally thinner than those in 47h, and historically there was less oak-hickory forest and more extensive tallgrass prairie than found in 47h.
Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... One can find the Statue of Liberty in Philadelphia. The Corn Belt, one of the many US Belt Regions, is located in the Midwestern region of the United States. Soils are deep, fertile, and rich in organic material and nitrogen, and the land is relatively level. Aside from the high production of corn, the area is also known for its high soybean production. However, most descriptions include Iowa, Indiana, eastern Nebraska, western Ohio, Illinois, sections of Missouri, southern Michigan, southern Minnesota, and eastern Kansas. Most of the oak-hickory forest, floodplain forest, and tallgrass prairie has been removed due to conversion to cropland, although some wetlands are being restored.
Over the years, the region has improved even more into what it is today. The dominant land use is cropland agriculture with some pasture and cattle feedlots.
In order to understand how the region became so crucial in the production of corn, then it is important to have an understanding of the history of the place. At least 40% of the global corn production can be attributed to the Corn Belt. Although cropland agriculture is widespread, this region has more areas of woodland and pasture than neighboring 47e. Corrections? The Missouri Alluvial Plain is part of the large, wide, flat alluvial plain found in five neighboring states.
Most farms in the area are family operated and average more than 300 acres (120 hectares).

Silty clay loam soils have developed on the loess. As its name implies, the Transitional Sandy Plain ecoregion contains some of the characteristics of Sand Hills (44a) in the west and the glaciated regions to the east. Major environmental concerns in the region include surface and groundwater contamination from fertilizer and pesticide applications as well as impacts from concentrated livestock production. By Ferdinand Bada on April 25 2019 in World Facts. All maps, graphics, flags, photos and original descriptions © 2020 worldatlas.com. It is the highest and driest region of the Western Corn Belt Plains, as it rises to meet the Northern Glaciated Plains (46) of the Dakotas. In the northern portion of the region, the glacial deposits are thin, and shallow limestone bedrock creates karst features such as sinkholes and sags. The warm nights, hot days, and well-distributed rainfall of the region during the growing season are ideal conditions for raising corn.
The deep loess-dominated hills have greater relief and a higher drainage density than the Steeply Rolling Loess Prairies (47e) to the east.
