STUDY OF WATER-PHYSICAL PROPERTIES OF IRRIGATED CHESTNUT SOIL TYPES IN THE CONDITIONS OF THE TERSKO-SULAK SUBPROVINCION
Under the conditions of the Tersk-Sulakskaya subprovincion, the main water-physical indicators of chestnut and meadow-chestnut soils were studied, which are characterized mainly by a satisfactory density of addition in the upper arable horizons, low water permeability, satisfactory water retention capacity, sufficient reserves of available moisture when saturated to the lowest moisture capacity. The water-physical properties noticeably deteriorate in the sub-arable horizons of the studied soils.
