Features of late Holocene evolution of Precarpathians soil

Abstract

Our aim was to determine changes of individual soil parameters for the 1000 BP in relevant environmental and
landscape conditions based on the study of buried and background (modern) soils in pedochronocatena. For profiledifferentiated soils are very important to compare their degree of differentiation of finely dispersed particles content as
one of the main indicators in their diagnostics.
Modern and buried soils morphologically are quite related, and some differences between them connected with the
intensity of gley, the presence of carbonates and inclusions. Morphometric parameters of buried soils are more differ
in background: the whole profile has 69 cm (buried soil) and 83 cm (background soil, it’s compared to the + 20%);
upper humus horizon – 17 and 24 cm (+ 41%); all humus horizons – 33 and 45 cm (+ 36%). The main reason of that
is the intensification of the radial flow of substance in ecotope for the time after the build an earthen rampart, which
occurred due in according to increase of the moisture rate. In the background soil was identified depletion of the
upper horizons of finely dispersed particles and their accumulation in illuvial horizons. Therefore, after the
construction of the earthen rampart (1000 BP) intra soil weathering processes and lessivage (leaching from clay
particles being carried down in suspension) as probably eluvial-illuvial redistribution significantly have become
stronger that overall are confirming growing of humid of climate. This has contributed to the radial migration of
substances as an intra soil weathering with of gley in situ.
