Physical Properties of Hydromorphic Soils Irrigating Khanka District of Khorazm Oasis

Abstract

This article presents information on the mechanical composition, volume mass, and specific gravity of old irrigated meadow alluvial soils developed on the alluvial deposits of the Khanka District “Galaba” massif. In the mechanical composition of these soils, the amount of sand is 22.9% in the driving layer and 39.25% in the lower layers, while dust particles are 59.2-72.2% and silt particles are 4.9% in the upper layer and 1.6% in the bottom layer. is %. In the lower part (110–150 cm) of the layer, the amount of fine sand and large dust particles is highly accumulated, and in the genetic layers of the old irrigated meadow soils of the massif, the specific mass varies from 2.42 g/cm3 to 2.66 g/cm3, which is characteristic for this area. It was 2.42 g/cm3 and 2.60 g/cm3 in the plowed layer of the studied soils, and the volume mass was 1.21–1.41 g/cm3 in the plowed layer of the soils, increasing downwards to 1.52–1, It is explained that it is densified over the entire section, making 53 g/cm3.
