The Application of Buried Soil Properties for Reconstruction of Various Stages of Early Habitation at Archaeological Sites in Moscow Kremlin

Abstract

Combined archaeological and pedogenetic study allows reconstructing the history of early habitation in Moscow Kremlin (Moscow, Russia). The area is confined to the third terrace of Moskva River with Podzols as native soils formed in fluvioglacial sandy deposits under virgin broad-leaved forests with conifers. From the Early Iron Age (1500–2000 BP) to the 12th century, alternating stages of agricultural land use and abandonment resulted in human-induced transformation of natural ecosystems into agricultural landscapes. Agricultural land use provoked soil erosion that lead to truncation of the upper soil horizons. Sediments deposited due to slope erosion and mineral materials transported by ancient people enhanced initial lithic discontinuity of soil parent material. Ancient agricultural practices included melioration of soils by mineral and organic fertilizers. During the Early Iron Age the pasture was fertilized by ash and limed by crushed dolomite. Melioration of the 12th century included not only ash and dolomite but also crushed bones, manure and household waste. A change from the agricultural to urban land use after 15th century resulted in the accumulation of cultural layers. A few interruptions in their accumulation, which were caused by accidental fires or other phenomena, were accompanied by regeneration of natural vegetation cover and the formation of shallow soils imprinted on cultural layers.
