Changes in the Degree of Soil Salinization in the Agrolandscape Under the Influence of Highly Mineralized Groundwater

The extent of distribution, the level of rise of groundwater, and the chemical composition depend mainly on the terrain and the quantitative and qualitative characteristics of precipitation. In conditions of increasing relief (middle of the slope), the GWL is lower relative to the lower part of the slope. On average, during this study, the difference in the occurrence of groundwater in a well from the middle of the field and a well in the lower part of the field is 4.4 times—343%. In conditions of increasing temperature in winter, precipitation is observed to have a liquid form, resulting in the increase in the subsurface runoff, which in turn affects the degree of mineralization of groundwater. The higher the concentration of salts in groundwater, the higher the degree of salinization of soil horizons. The predominant ions in the mineralization of natural waters also dominate among the ions of soil salts.
