Аннотация
Taking into account the soil and agroclimatic zoning, comparative characteristics of the distribution by depth of soil soaking in the Rostov Region by atmospheric precipitation and their influence on the depth of occurrence of carbonate new formations were studied. The objects of the study were all zonal soil types widespread in the Rostov Region: ordinary carbonate chernozems, southern chernozems, dark chestnut, chestnut and light chestnut soils. The analysis of the frequency of occurrence of the most common soaking depth was carried out within various zoning objects: agroclimatic regions, climatic subregions, and soil regions. Open sources of information were used to determine the average long-term soaking depth of the profile of the studied soils and to calculate the frequency of occurrence of the most common wetting depth over a 33-year period. Interpolation of soaking depths was carried out using the method of inverse distance weighting using the ArcMap 10.4.1 software. It was revealed that the hydrothermal conditions of soil formation determine the average long-term soaking depth, which decreases from the west to the east within the Rostov Region, correlating with the depths of the appearance of micellar forms of carbonates and the formation of the white-eye horizon. This indicator testifies to clear geographical patterns: the greatest depth of soaking is characteristic of the soils of the south-western part of the Rostov Region and belongs to the seaside regions of the Northern Azov Sea. The soils of the eastern territories of the region are characterized by a less soaking depth, and the further south they are formed, the lower is the indicator. The distribution of soaking depths, taking into account the soil zoning, gives a more detailed picture, which makes it possible to track the dynamics of carbonate migration processes depending on the moisture availability and soil conditions.
