摘要：

A critical analysis of existing approaches to an assessment of initial vertical parent material uniformity was carried out. The depth function of Ti, Zr, Y contents and ratios in the profiles of two forest-steppe soils formed in usual for the Middle Volga region loose deposits were studied. For diagnostics of parent material uniformity being based on a stable index constituent it is necessary to use special methods of preparation of samples for the analysis, or such sampling scheme within individual pedons, which allows to estimate reliability of results statistically. For realistic interpretation of the Ti, Zr and Y depth distribution it is recommended to use different ways of soil sample decomposition.
