Malyk S. Brown-podzolic soils of the Pre-Gorganian Pre-Carpathian

On the one hand, the main aim of the thesis is to establish the genesis of the brown-podzolic soils which is based on a detailed study of the soils’ characteristics, its silt fraction and neoplasms. On the other hand, to define the diagnostic criteria for basic elementary soil processes (ESP) such as: lessivage, internal soil argillization, gley-elluviation and podsolization. The analysis of the genesis allows us to confirm that the profile of brown-podzolic soils is formed by processes different in mechanism, but similar in result. Therefore, the diagnostics of these processes should be supplemented by the results of the analysis of the gross chemical composition of the silt fraction and soil neoplasms. Based on the results of the gross chemical composition, it was established that the investigated soils were formed by the processes of lessivage, internal soil gleying and, to a lesser extent, podsolization, internal soil gley-elluviation.
