New experimental data have been obtained from studying he soils of the Northern coast of Lake Baikal. This research provides a detailed description of the soils characteristic for the study area. The indicators of acid-alkaline conditions were determined. According to the degree of biological activity of the soils used in the study, they are categorized as moderately and weakly active. The study revealed a noticeable (on Chaddock’s scale) relationship of this activity with acid-alkaline conditions (R2 = 0.7). The quantitative-qualitative characteristics of the soil microbiocenoses are considered in detail. The heterotrophic eubacterial count varies over a broad range depending on the type of soil (from 0.27 to 8.2 million CFU/g). Qualitatively, the fugal component is very diverse. Sanitary-microbiological indicators of the soils were determined for the lakeshore in the vicinity of settlements, garages and dacha gardens as well as in the recreation zone.
