Title: Гумусовые профили почв подтайги Западной Сибири
Abstract: Western Siberia subtaiga soils have complex humus profiles. Availability of 2 or sometimes 3 zones (layers) with relatively wide Sgk and Sphk correlation, increased GK part espessially potassium humate and relatively decresed Phk part is mentioned in the grey forest soils with the absence of morphologically frank relict features. Humus profiles are more complicated in the sod-podzol soils due to the second humus horizonts which profile posture allows to consider them, according to A.L. Alexandrov (1988, 2002), to be of the first or second type. They greatly differ by the Sgk:Sphk size, GK and culcium humate storage level in its content. These features can testify to humus formation in this profile part in less moistured and warmer conditions. The data confirm poligenetic nature of the Western Siberia Subtaiga soils humus profiles of which mark all the soil formation stages and phases.
