This is a list of U.S. state soils. A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These official state soils share the same level of distinction as official state flowers and birds.
Map of the United States showing what percentage of the soil in a given area is classified as an Ultisol-type soil. The great majority of the land area classified in the highest category (75%-or-greater Ultisol) lies in the South and overlays with the Piedmont Plateau, which runs as a diagonal line through the South from southeast (in Alabama) to northwest (up into parts of Maryland).
Coordinates: 36.0455°N 78.4907°W. Originally mapped in Cecil County, Maryland in 1899, more than 10 million acres (40,000 km 2) of the Cecil soil series (Fine, kaolinitic, thermic Typic Kanhapludults) are now mapped in the Piedmont region of the southeastern United States. It extends from Virginia through North Carolina (where it is the state ...

Bauxite forms by the weathering of aluminum-rich and silica-poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.

Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al 2 Si 2 O 5 ( OH) 4 ), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces . Clay minerals form in the presence of water [ 1] and have been important to life, and many theories of ...
