Teymurov S.A., Imashova S.N., Ramazanov A.V. INFLUENCE OF AGGREGATION OF CHESTNUT AND MEADOW-CHESTNUT SOILS ON THEIR AGROPHYSICAL PROPERTIES IN THE TERSKO-SULAK PLAIN // Arid ecosystems. 2021. V.27. № 3 (88). P. 89-95.
The data of studying the physical properties of chestnut and meadow-chestnut soils are considered. The dependence of the density of the studied soils on both the size of aggregates and the features of the soil formation process is shown. In each particular case, this dependence is closely related to the genesis of soils and the peculiarities of their agricultural use. When considering the porosity of aggregates, estimated by the percentage of fractions, it is seen that the main share of interaggregate porosity in the studied soils is accounted for by large aggregates. The results of the obtained studies can be extrapolated to other areas of the soil cover of the studied area.
Keywords: soil structure, aggregate, density, porosity, genetic horizon.
