Abstract

 The soils of agricultural land are degraded, which affects their productivity. Soil properties reflect the ability of soil to prevent the processes of degradation. The article presents materials on the study of chestnut soils of Volgograd region in the system of protective forest belts on arid agricultural lands. The purpose of the study, conducted in 2021, was to establish the spatial impact of protective forest strips on the physico-chemical parameters of the soil in the conditions of a low steepness of the slope of the eastern exposition. To achieve this goal, we investigated theoretical and methodological materials on the experimental plot and studied the selected samples by conducting laboratory analyses of the main indicators (granulometric composition, soil structure coefficient, soil density, organic carbon).  As a result of the study of samples from points near the forest belt and within it the following was revealed: high content of organic matter (up to 1.47%) and high density (up to 1.53 g/cm3), sandy loam soil with a light granulometric composition and high content of agronomically valuable aggregates (0.25-10 mm), the structure factor above 1.6. Outside the forest belt and up the slope low carbon content (not more than 0.84 %) low density (not more than 1.32 g/cm3), soil has heavy granulometric composition, structure coefficient decreases to 0.86.
