| Abstract [eng] |
Vertical alternation of chemical composition in Lithuanian soil profile has been investigated in the study. Investigations are based on the certified analytical data, by applying standard mathematical–statistical data processing that enables to justify the vertical distribution patterns of trace and major elements and obtain internationally comparable concluding results on the national soil geochemistry. Soil grain size analysis and chemical analysis of separated sand, silt and clay particles revealed the relation between the soil grain size and chemical composition. Investigation of chemical composition of the soil parent material reflected its dominance as soil forming factor. Geochemical survey of the 74 individual soil profiles, representing all soil regions and main soil types, allowed to expose various soil forming processes and on its background to generalize geochemical features and ascertain the dominant ones in the sand–loamy sand and the loam–clay soil of Lithuania. On the base of original geochemical data the model geochemical soil profile was created and the dominant geochemical process was determined – element depletion and removal out of soil profile prevails in Lithuania. |
