PARTICULARITIES OF SOIL FORMING PROCESSES IN STEMNIC (BUDA) BASIN

Abstract

The paper proposes the study of pedogenetic processes in Stemnic (Buda) basin in close connection with natural factors (rocks, relief, water, vegetation) to which is added human activity. In order to understand the distribution of the soil types in the study area is analysed the distribution and intensity of the pedogenetic processes. Representative pedogenetic factors have acted at the same time, resulting processes such as bioaccumulation, cambization, salinization and alkalization, gleyzation and stagnogleyzation, carbonation and last but not least shrinking-swelling. Bioaccumulation is omnipresent in the basin, being represented by an Am horizon with humus accumulation in the first 25 cm, on 44% of the carted surface, and an Ao horizon with a reduced content of organic matter. Clay illuviation is specific for luvisols, appearing on 31.8% of the mapped surface, then cambization on 12%, following in decreasing order of the surfaces by alkalization and salinization, gleyzation and stagnogleyzation and with only 2% vertisoils.
