Anthropogenic impact on grain-size distribution and agrophysical properties of soils of cultivated rice lands of Kuban

et al. 2021

This work reviews the relation of the grain-size distribution and impact of the use of rice rotation soils on the main agrophysical indicators of soils that determine the composition and properties of soil cover of modern delta of Kuban. The regularities of dependence between the density of the matrix soil and the grain-size distribution that consist of mineral composition of alluvial soils and rocks have been identified. The trend towards increase in soil density with increase in physical clay and silt content, as well as increase in matrix soil density has been established. No significant differences in agrophysical properties of subsurface soil horizons and underlying formations have been identified. The agrophysical indicators of soils of rice fields and boharic analogues during their agricultural use have been assessed. The hydromorphic soil-forming processes did not lead to considerable changes in agrophysical properties of alluvial formations and soils involved in rice rotation.

Modern characteristics of the properties of meadow-boggy soils of rice agrocenosis in the republic of Adygeya

et al. 2021

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.
