Soils of the Eastern Priol’khonye on the coast of the lake Baikal: current state and use

In summer periods of 2015-2017 within the framework of complex expeditions in the eastern Priol’khonye soil geochemical researches were performed. More than 120 soil samples were collected for subsequent physical and chemical analyses. Ecological, chemical and physical properties of meadow and steppe soils of Ol’khon district were studied and the results are presented in the article. The research was conducted on the east coast of the Lake Baikal in its central basin, which is most visited by tourists. Several soil types can be found along the coast line and on gently sloped surface nearby, they are: castanozems, umbrisols, cambisols, gray soils, histic fluvisols gleyic, humic fluvisols gleyic, chernozems, umbric fluvisols, cambic fluvisols and other. Owing to a specific environmental conditions some original soil types (for example “chestnut soils”, “castanozems”) can be found nowhere else in the Irkutsk region but only here. The explored soil profiles are mainly thick and stony to various extent (from high to medium),these soils are sandy or sandy loams, rich in humus, predominantly with neutral and weakly alkaline reaction (pH), low content of nitrogen in relation to carbon content (C : N), that creates favorable conditions for preservation of the vegetable remains in meadow landscapes...
