Al–Fe–Humus Podzols in Russia: Geography of Some Properties
2020
Alyabina, I. O. | Shmatova, A. G.
The properties of representative soil profiles of podzols included in the database of the Unified State Register of Soil Resources of Russia are considered. As a result of processing and analysis of the data array (53 measured profiles), the ranges of values of a number of parameters have been corrected. It has been revealed that, in most cases, the ranges of properties of podzols are wider as compared to the estimated profiles given in published works (the thickness of the Al–Fe–humus horizon and the humus content in the E horizon). However, the range of values of the humus content in the illuvial horizon is narrower. We revealed specific features of podzols in particular regions received as a result of consolidation of soil provinces of the Map of Soil–Ecological Zoning. Regularities can be seen in the geographical distribution of the thickness of profiles of these soils and the content and profile distribution of humus. The humus content is maximal in the eluvial soil horizons in Siberian regions and in the illuvial soil horizons in the European Russia and Primor’e.
