Land erosion hazard comprehensive assessment of SZAO Legostayevskoye

The purpose of the study is to assess the erosion hazard from water and wind erosion of soils on the territory of the Legostaevskoye SZAO (agricultural closed joint stock company), located in the Novoselovo District of the Krasnoyarsk Region. The object of the study are lands subject to erosion processes (from water and wind erosion of soils). In the course of the study, the followimg methods were applied: observation, measurement, analysis, classification of eroded lands. When using large-scale topographic, soil maps, slopes subject to erosion processes from heavy rains were identified, on which the magnitude of the potential washout at each hundred-meter segment was determined, taking into account the shape of the slope, slope, topography, and soil type. The application of a set of anti-erosion measures based on the results of calculating the potential washout from storm water, taking into account the erosion hazard class, is considered. An assessment of the potential growth of ravines was carried out, the maximum sizes of erosion forms, the intensity of linear erosion, and the stage of development of the ravine were determined. An assessment of potential soil deflation, distribution, intensity of deflation on the territory of the farm, depending on the wind regime and soil deflation was carried out. The normal course of natural processes is greatly influenced by human economic activity. On the one hand, the unreasonable use of land leads to an increase in the process of soil degradation as a result of the development of erosion, the loss of its potential and effective fertility. The purely natural conditions of the territory where erosion is highly developed are not in themselves the cause of its development; they only intensify this process after the balance in nature has been disturbed by man. On the other hand, rational management, farming on a scientific basis, taking into account the natural course of processes and the possible consequences of human activities, is a reliable guarantee of preserving and increasing land fertility. A complex of organizational and economic agrotechnical, reclamation, hydrotechnical and organizational and economic measures, primarily the anti-erosion organization of territories, contributes to the prevention of erosion processes. As a result of the study, based on the results of the assessment, a map of the erosion hazard of the lands of the SZAO (agricultural closed joint stock company) Legostaevskoye in the Novoselovo District of the Krasnoyarsk Region was compiled.
