Sod-eluvozems have formed on the terraces of the Kama river covered by thin (0,5–0,8 m) ancient alluvium of arenaceous-loamy sandy granulometric composition under mixed forests. Well differentiated eluvial horizon with iron-humus ortsteins is bedded in the profile under grey-humus horizon. Silty bedrock is under eluvial part of the profile. There are mixed stratums of clay and sand. Psammozems are formed in the parts of the deeper aggradations of sand compositions under pine forests. Sod-eluvozems have humus profile of forest type. The amount of humus contrastingly decreases in eluvial horizon. The soils are acid, with low absorption capacity and base saturation. The tendency to acid decrease and considerable increase of base saturation is registered in underflooding sod-eluvozems. The probable areal of sod-eluvozems on the banks of the Kama reservoir is determined on the basis of GIS technologies . The area is about 140 km2. The areal is determined by absolute levels of altitudes of the Kama benches, on which two-layer soils were rergistered.
