Genetic specificity and geography of taiga soils in the central part of the Baikal region

Abstract

A specific feature of the development of automorphic taiga soils in the Baikal region is the lack of correspondence between the weak intensity of the soil chemical weathering and the high intensity of the removal of alkaline-earth elements from the soil profile in the form of suspensions. The loss of the clay fraction affects the water-physical properties of these soils and their temperature regime. The areas of different soil types in the northern and middle taiga zones have been calculated on the basis of soil maps of different scales. It is shown that podburs and acid soddy taiga soils predominate in these zones; the area of podzols, which were previously considered to be the dominant soil type in the middle and southern taiga zones, is smaller.
