In recent years, because of the strengthening of natural and anthropogenic factors, the non-drainage of the Amu Darya and Syr
Darya waters into the Aral Sea has led to the predominant formation of various soils on the dried sea bottom. When studying the
degree of salinity of desert-sandy soils in studies, it was found that in the surface layer of soil in section 47, i.e., in layers at a
depth of 0-9 and 9-50 cm, the salinity of the soil is of the chloride-sulfate type, and the lower The soil profile layers are sulfate-
chloride and saline; low salinity is noted. The amount of humus in the surface layer of the studied desert sandy soils, 0-9 cm and
9-50 cm layers, is fixed in the range from 0.418% to 0.528%.
