The soil cover in the raised areas is comprised of podzolic soils. Peaty podzolic gleyic, gley and peat-gley soils develop on beach ridges, at the foot of the ridges, in depression between them.
Hydromorphic podzolic soils of the eastern shore are characterised by the accumulation of the hystic organic horizon, acidity and eluvial-illuvial differentiation of the chemical elements among horizons. Soils in the territory are considerably water-logged, which was enhanced by clear-cutting in raised areas in the recent past.
The Olonetskaya plain soil cover is quite composite and diverse. It is represented by soils with various degrees of gleization - pseudogley sod, gley and sod-gley soils. Soils without gley signs show limited distribution, and are found on river and stream edges. The features of surface gleyed soils are acidity, humate-fulvate humus and thin layer involved in soil-formation processes.
Peculiarities of the eastern shore
Ancient cheniers shaped as asymmetric ridges of 0.5 to 1 km long add complexity to the topography of the low
accretion plain. The soil cover in the raised areas is comprised of podzolic soils, while peaty soils develop in depression between ridges. In general soils in the territory are considerably water-logged.
The surface of the Olonetskaya plain, gently sloping towards the lake, is made up of thick deposits of various grain sizes and genesis with widely spread varved clays. The soil cover is represented by soils with various degrees of gleization and thin layer involved in soil-formation processes.
