Abstract:
This article systematically analyzes the scientific and theoretical foundations of erosion processes in irrigated areas, in particular, the physicochemical mechanisms of erosion occurrence, the main causes of soil degradation, and the patterns of erosion development under the influence of irrigation water. The main goal of the research is to scientifically identify the processes of erosion and degradation arising as a result of irrigation, to clarify the factors that form them, and to illuminate the patterns of their interrelationship. According to the analysis results, erosion processes are not limited to surface erosion, but are accompanied by physical and chemical destruction of the soil structure, ion exchange, dispersion, and a decrease in salinity and infiltration. The quality, norms, methods of irrigation, and frequency of irrigation water application are defined as the main factors that intensify these processes. Soil porosity, pH equilibrium, sodium sorption coefficient (SAR), and organic matter content were identified as the main indicators characterizing the risk of erosion. The results of this scientific article serve as a scientific and practical basis for assessing degraded irrigated lands, forecasting risk zones, and developing agrotechnical and land reclamation measures for erosion prevention.
