The article presents an interdisciplinary study (soil studies, paleogeography, geochemistry, etc.) of occupation layers and soils at Ilmensky excavation site in Veliky Novgorod. The evolution of the landscapes, soils and anthropogenic deposits has been studied. The buried native soil under the occupation layer (up to 2.5 m) is forest vegetable earth and podzol, with a ploughing horizon. The occupation layer is represented by two types: organic anaerobic and organomineral aerobic. Immature “ploughing-and-garden” soil (middle of the 12th c. – beginning of the 14th c., layer of hiatus) has been studied, in the organic stratum.
