State and centennial dynamics of microbial communities in paleosoils of steppe kurgans within historical time

Annotation

Microbiological studies of paleosoils of archeological monuments (III mil. BC – AD XVIII), located in the dry steppes of Lower Volga region, were conducted. The obtained data demonstrates that in paleosoils the microbial communities are maintained. Their total biomass amounts 20–105 %, the living one –48–142 %, the active one –0,2–35 % of the respective levels of the biomass in the modern soils. The paleosoils of archeological monuments in the steppe zone are unique object, preserving information on the status of soil microbial communities within past historical time.

Keywords
