The USDA soil taxonomy [16] and the Chinese soil taxonomy [17] call these soils Spodosols. [18] The Canadian system of soil classification matches Podzols with soils under the Podzolic order (e.g. Humo-Ferric Podzol). [19] [20] The Australian Soil Classification [21] uses the term Podosols. The Brazilian Soil Classification System [22] calls ...
The result is that leaching of the soil profile occurs; in which mobile chemicals are washed out of the topsoil, or A horizon, and accumulate lower down, in the B horizon. These soils have large amounts (more than 5%) of organic carbon in the surface horizon, which is therefore dark in colour.
Podzol soil monolith with inconspicuous eluviation; coarse granular structure of top mineral horizon (Ahe or Ap) is evidence of earthworm invasion. These acid soils have a B horizon containing accumulations of amorphous materials composed of humified organic matter associated with aluminum and iron.
Charlottetown soil series is the name given to a deep fine sandy loam soil which has developed under forest vegetation on glacial till. This series occurs only on Prince Edward Island , where it is widespread and so important for agriculture that it has been designated as the Provincial Soil.
It belongs to the podzol soil group and is one of the most important soils in its area of occurrence, supporting extensive forests and a fair number of farms. Many Berkshire soils lack the eluvial (E) horizon characteristic of podzols because they have a history of being cleared for cultivation.
Chernozem (/ ˈ tʃ ɜːr n ə z ɛ m / CHUR-nə-zem), [a] also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus [3] (4% to 16%) and high percentages of phosphorus and ammonia compounds. [4] Chernozem is very fertile soil and can produce high agricultural yields with its high ...

The soil texture is usually loamy sand or sandy loam, but pure sand horizons may also be encountered. The usual soil classification is Orthic Dystric Brunisol. [1] A Gleyed Humo-Ferric Podzol example is also known, although that profile does not have the eluvial (Ae or E) horizon characteristic of classic Podzol development. [2]
