In this work, changes in the composition and properties of alluvial meadow-boggy soils are considered, with prolonged use in rice crop rotation and not involved in agricultural production - a virgin plot. The morphological differences of meadow-boggy soils of a rice field from a virgin area were revealed, which subsequently determine the properties of the soil cover of the Kuban River delta. The regularities of the interdependence of the granulometric composition of the soil, which lie in the mineralogical composition of alluvial soils and rocks, have been revealed. The tendency of an increase in soil density with an increase in the content of physical clay and silt, as well as an increase in the density of the solid phase of soils, has been established. No significant differences were found in the indices of the agrophysical properties of the subsurface horizons of soils and underlying sediments. The assessment of fertility indicators of meadow-boggy soil of a rice field and virgin analogue is given. Hydromorphic soil-forming processes have led to a significant change in the properties of alluvial deposits and soils involved in the rice crop rotation.
