Methodological bases for studying erosion processes in the conditions of the Kabardino-Balkarian Republic

Abstract

The assessment of the ecological state of the soil involves determining the correspondence between the processes in the studied soils and their natural counterparts, which makes it possible to identify the permissible value of a particular factor, incl. agrotechnical, established according to the criterion of compliance with the normal functioning of the natural ecosystem. It is shown that the study of erosion processes in areas with an area that in modern land use is similar to the areas of agricultural land of large farms requires taking into account the quantities (factors) that predetermine both the wash itself and its intensity. It has been established that the rate of increase in the humus profile during the formation of various soils is not the same. The characteristics of the erosion threat of soils are given in accordance with the level of their manifestation for the conditions of Kabardino-Balkaria. As a result of the studies, it was found that the determination of the effect of steepness on soil erosion from slopes in its pure form cannot be performed, since such a process is due to the individual characteristics of an additional set of factors that can only be obtained by studying the relief using different approaches. Therefore, it is necessary to analyze the regional features of the experimental area, which will reduce the errors that arise when using existing mathematical models of water erosion, and at the same time correct them, adapting them to regional conditions.
