is an important process in their formation, to divide them according to podzolization
degree is not meaningful.
The POD index was chosen, as it relates directly to podzolization
(rather than a variety of different soil development parameters) and allows rapid comparison with index values from other studies, unlike the frequently used Profile Development Index (Harden 1982), where different soil parameters and scales may he selected for each study.
If the sand content of the till is very high, development in the topsoil has gone beyond the stage of BrownEarth, by more or less intensive secondary podzolization
In a strip in the south of the biome, between the true podzols of the taiga proper and the luvisols of the deciduous forests, there are soils that share some of the formation processes that occur in the two areas, podzolization
and the illuviation of clay (see vol.
with an iron or clay hardpan, and low amounts of available nutrients and organic matter.

Clear 33-year contemporary podzolization
was evident in pure sand overgrown with green mosses and covered with the newly formed forest floor during this time (Reintam 2001a).
The dominant processes in these zones are podzolization
and soil organic matter transfer in soils of Antarctica.
Increased fire frequency, from Kalkaska to Rubicon to Grayling sites, is postulated to not only retard forest succession to more mesophytic species but also to destroy more completely the O horizon (the litter layer), which is the source of organic acids for the podzolization
process (Mokma and Vance, 1989; Schaetzl, 1994).
