podzol

Geology and Earth Sciences

Soil profile formed at an advanced stage of leaching by the process of podzolization, and identified by its acid mor humus, eluviated and bleached E soil horizon, and an iron-coloured B horizon, enriched with a variety of translocated materials. See also spodosols.

Geography

A soil characteristic of the coniferous forests of Russia and Canada. Podzolization occurs when severe leaching leaves the upper horizon virtually depleted of all soil constituents except quartz grains. Clay minerals in the A horizon decompose by reaction with humic acids and form soluble salts. The leached material from the A horizon is deposited in the B horizon as a humus-rich horizon band or as a hard layer of sesquioxides. See Sauer et al. (2007) J. Plant Nutrit. & Soil Sci. 170, 5 for a review of the present knowledge on the development, functions, and threats of podzols in 2007.
