For the studied saline soils, the expediency of assessing the content of mobile ion compounds by chemical autography based on electrolysis and ionite membranes, vertical electrical sensing is shown. However, the electrical conductivity of soils depended on humidity, temperature, humus content, granulometric composition, soil density, and fertilizer application. The change in the nature and degree of soil salinization over time and in space was determined not only by the microrelief of the surface, groundwater and the change in the depth of the umbrellas in density, but also by the patterns of solubility of salts from humidity, temperature, pCO2, complex formation. For relative optimization of the situation, it is recommended to apply mineral fertilizers, stimulants, organic fertilizers, and create a large-porous layer at a depth of 40-70 cm, reducing the upward current from the lower layers of the soil to the Ap.
