Each state in the United States has selected a state soil, twenty of which have been legislatively established.

Although the United States has many sites with contaminated soils, it has been a leader in defining and implementing standards for cleanup. [4] Each year, thousands of sites complete soil contamination cleanup, some by using microbes that “eat up” toxic chemicals in soil, [5] many others by simple excavation and others by soil vapor extraction, air stripping, or solvent extraction, with ...
Such maps are typically richer in context and show higher spatial detail, yet are not necessarily more accurate than traditional soil maps. Soil maps produced using (geo)statistical technique can also include an estimate of the model uncertainty. [3] An example of a traditional soil map showing soil mapping units, described soil profiles and ...

The soil suborders within an order are differentiated on the basis of soil properties and horizons which depend on soil moisture and temperature. Forty-seven suborders are recognized in the United States. [6] The soil great group category is a subdivision of a suborder in which the kind and sequence of soil horizons distinguish one soil from ...
Ecoregions may be identified by similarities in geology, physiography, vegetation, climate, soils, land use, wildlife distributions, and hydrology. The classification system has four levels, but only Levels I and III are on this list. Level I divides North America into 15 broad ecoregions; of these, 12 lie partly or wholly within the United States.
