Аннотация: Pedoanthracological methods have never been used for studying natural and anthropogenic factors of ecosystem dynamics in the area of the Middle Russian Upland. The article presents results of the first study of soil charcoal stratigraphy, taxonomy, and radiocarbon dating combined with morphological analysis of soil profiles performed for sandy soil (Podzols and Arenosols) in the Meshchera Lowlands. Charcoal samples from different soil patterns and horizons were taken from 19 soil pits in four forest sites. The taxonomic identification of charcoals was performed for 24 soil samples; 12 charcoal samples were radiocarbon-dated. The following three patterns of ancient pedoturbations were studied in the soil profiles: arable layers, root channels, and pits formed after treefalls with uprooting. Results of soil charcoal analysis were compared with pollen and microscopic charcoal analysis of the cores taken in the surrounding peats. Pinus charcoals of various age prevailed in all charcoal samples. Charcoal of Betula and Sorbus also occurred. The oldest charcoal fragments were 2610 cal. BP. The remaining charcoal samples were mainly grouped into three clusters: about 2200, about 900–1000, and later 500 cal. BP. We assume that most charcoal samples were associated with burning and subsequent plowing which provided the upper layer of the soil (arable layers and sometimes root channels) with charcoal fragments. Charcoals were most abundant in the deepest pits formed after ancient treefalls. Periods of accumulation of charcoals in the peatlands and in the soil did not coincide for the last several millennia in the study region: intensive mixing of charcoals into the soil began after a decrease in the flow of charcoals into the peats. We associate this with the changing dynamics of landscapes under the influence of anthropogenic factors.
