In this article, the authors have developed and used soil morphogenetic indicators in the course conducted ground field work to determine saline and waterlogged soils in the semi-desert and dry steppe, zones of the Abay, Pavlodar and Karagandy regions of Kazakhstan. In Kazakhstan, there are no practical and scientific provisions for monitoring and managing saline and waterlogged soils based on digital technologies. This development makes it possible to determine the location of such lands depending on the location of soil and climatic zones. And also, the development of a cartographic model of these soils with the determination of the degree of their salinity makes it possible to develop recommendations for their development (improvement) with the subsequent preservation of productive longevity. The study of the current state of saline and waterlogged soils was carried out through field work along routes covering the territory of 3 administrative regions of the republic. Descriptions of the state of soils were carried out at 28 base points. A database of saline and waterlogged soils of the semi-desert and dry steppe (latitudinal), zones has been compiled, including the following indicators: soil type and subtype, profile morphology, content of humus and nutrients, water-soluble salts, particle size distribution, absorbed bases, and cation exchange capacity.
