Morphological structure, agrophysical and agrochemical properties of irrigated typical gray and grass soils

Abstract

The article presents information on morphological structures, general physical and agrochemical properties of typical irrigated gray and grassland soils. The general physical properties of the soil are that in typical gray soils the bulk density decreases and the porosity increases, while in grassland soils the bulk density decreases and the total porosity increases compared to typical gray soils. A typical irrigated gray soil is composed of large dust particles according to its mechanical composition and belongs to the category of medium sandy loam. According to the level of availability of humus and nutrients of the studied soils, typical gray and meadow soils irrigated are low in humus (0.36-0.87%), very low in mobile phosphorus (5.33-15.60 mg/kg), exchangeable potassium It is highlighted that it is provided with low (100-200 mg/kg).
