THE PROBLEM OF SOIL DEFLATION IN THE AGROLANDSCAPES OF VOLGOGRAD REGION ARID ZONE

Background. The climate is changing towards aridization and increasing on anthropogenic impact lead, among the other things, for example, a deflation, a loss of soil fertility and a desertification of agricultural landscapes, which negatively gives effect on their environmental sustainability and agricultural productivity. Purpose. It is needed to identify the influence and mechanism of influence of deflationary processes on the ecological balance of agricultural landscapes, and we need to solve some unresolved problems and ways to develop research on wind erosion of soils in the arid zone. Materials and methods. The methods of research of agricultural landscapes were used (methods of FGBNU VNIALMI, FGBNU "Rosinformagrotekh", State Scientific Institution VNIIZPE), which used generally accepted methods. Agricultural landscapes were built by using various agricultural technologies were studied as objects. Results. The revelation of those data proved that the stability of agricultural landscapes is high with direct sowing technology, where the level of deflation is 8%, while the classical agricultural technology it is 31%. The mechanism of soil and territory degradation in the conditions of Volgograd region under the influence of deflation and the level of decrease in arable land productivity, where the damage to agricultural production in the region was amounted to 27.6 billion rubles, have been established also. The influence of the entire complex of anthropogenic impacts on the properties and structure of soils included their erodibility, deflationary activity and, in general, on the formation of ecologically balanced agricultural landscapes which has been proven successfully. The promising areas of research have been identified also in this article. Conclusion. We proved that new experimental material on deflation in the zone of light chestnut soils has been obtained. Soil deflation was pronounced using classical agricultural technology. The need to develop a system of criteria for assessing the territories of the arid zone of the Russian Federation and methods for mapping territories. EDN: DYZGZF
