| Abstract: | Al-Fe-humus podzols developed from sandy materials of continental and marine origins can be arranged into the following sequence with respect to the degree of soil hydromorphism: iron-illuvial podzols—humus-illuvial podzols—dark (high-humus) humus-illuvial podzols—peat podzols. These soils do not differ much in their particle-size distribution and bulk elemental composition. The most informative indices reflecting the effect of soil hydromorphism are the contents of oxalate-extractable iron and aluminum compounds and the contents and composition of the soil organic matter. |
