THE MORPHOLOGY OF THE FLOODPLAIN SOILS OF KRASNOYARSK FOREST-STEPPE

The paper is devoted to the floodplain soils ofKrasnoyarskforest-steppe. The aim of the paper is to characterize the morphological properties of the floodplain soils of small rivers (tributaries of theYeniseiRiver): the Berezovka, the Esaulovka, the Kacha and the Buzim in theterritoryofKrasnoyarskforest-steppe. The authors continue a comprehensive study of floodplain soils, which is supported by new materials. The dominant type, elementary dominant soilforming processes for all the studied floodplain soils of small rivers of theKrasnoyarskforest-steppe are determined. The research reveled the characteristics of macro-morphological and micro-morphological properties of alluvial peatgley soils, black soil and dark humus alluvial soil – the dominant soil types which occur both at low and at high levels of floodplains. There are the sub-types of the dominant soil type: alluvial dark humus hydro-metamorphosed soils (typical for floodplains of the river Berezovka); alluvial dark humus gleyey soils (typical for floodplains of the Esaulovka, the Kacha and the Buzim). The sub-type depends on the varying degrees of the soils development and the width of humus horizons. The evaluation of floodplain soils in terms of their fertility and evolution was perfprmed.
