Podsolisation is an extreme form of leaching which causes the eluviation of iron and aluminium sesquioxides. [1]The process generally occurs in areas where precipitation is greater than evapotranspiration.
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. They develop most commonly in sandy materials ...
The classic podzol horizon sequence, since podzols are strongly acidic: in these soils, a pale eluvial (E) horizon lies under the organic surface layer and overlies a dark B horizon; Presence of a caliche layer indicates the presence of calcium carbonates, which are present in alkaline conditions; Columnar structure can be an indicator of sodic ...
Brown podzolic soils are a subdivision of the Podzolic soils in the British soil classification.Although classed with podzols because they have an iron-rich, or spodic horizon, they are, in fact intermediate between podzols and Brown earths.

Podzol soils (Polish: Gleby bielicoziemne; WRB: Podzols; ST: Spodosols) That order groups all soils where main soil developing process was podzolisation , spodic horizon is diagnostic for that group.
