The article deals with the information about a general state of the grey–meadow, meadow–grey, grey and grey–brown soil fertility used under the cotton plant for more than 60 years and irrigated since ancient times. A geographical situation, geological–geomorphological, soil–climate and soil–meliorative state of the lowland have been characterized. The diagnostic parameters of the soils which dominate in the lowland have been analyzed, the information about fertility protection and their exploitation under the cotton plant in future has been shown.
