The article presents datas on the gross chemical composition of buried soils of Subatantic and Subboreal periods, that’s located on geosystems floodplain of the Middle Volga. Based on the evaluation of geochemical factors justified bioclimatic conditions of their development, as well as the peculiarities of the process of soil formation. The comparative geochemical characteristics of buried soils with their zonal analogues (leached chernozem).

The article presents data on the development of approaches to the reconstruction of the paleo-environment of the habitat of the Lugovo culture by means of the conjugate analysis of the soil-archeological and geochemical parameters of the soils of settlements and buried soils of the burial mounds. As a working hypothesis, it was suggested that meadow-steppe conditions for the formation of geosystems of the period of development of the Lugovsk cultural-historical community, dating back to the 15th–14th centuries.
