The article describes in detail the morphogenetic features of desert sandy, takyr-like, residual takyr residual meadow soils. From
the very beginning (since 1960), it was noted that automorphic soils formed on large areas of land where water receded. The
formation of automorphic soils on the drained seabed is primarily due to the fact that groundwater has sunk below the level and
has little effect on soil formation. Also, the formation of the soil is associated with the lithological and geomorphological
conditions of the area in a dry climate. It was noted that the formation of automorphic soils was manifested in the morphogenetic
structure of soils, that is, in the formation of salt crystals, the formation of rust spots in the lower parts of the layer.
