RELICT FEATURES OF MUCUOUS SOILS IN THE KURPIE PLAIN

摘要

The area of Kurpie Plain features mucuous soils (sandy humous soils) containing from 3 to 10% of organic matter in the humus (top) layer. These soils developed from loose sands of fluvio-glacial origin. The morphology of these soils indicates the prior processes of podsolization and gleyization. The profile distribution of those elements soluble in 20% HC1 as well as free iron, indicate the podzolization effect.
