Fluctuation of the values of the qualitative characteristics of reservoirs in the Saratov region during the growing season

Abstract

The article presents the results of determining the quality indicators of water from several ponds No. 3 (drain), No. 4 (non-drain), No. 8 (drain) Privolzhsky branch of the Federal State Budgetary Institution “Management “SARATOVMELIOVODKHOZ” of the Marksovsky district of the Saratov region. In the course of the studies carried out, it was revealed that during the growing season, under the influence of fish-breeding processes and the ability of reservoirs to self-purification, as a result of the vital processes of various hydrobionts, the chemical and microbiological characteristics of water changed for the better. Introduction. Our country is characterized by a wide variety of different conditions, including hydrological and climatic, which entails different types of environmental management, as well as differences in the intensity of development. Currently, there is a progressive deterioration in the quality of the aquatic environment, which is a threat to Russia’s vital national interests in the areas of environmental, food and national security. Environmental protection has recently become of world importance. Pollution of water resources, atmospheric air, soil and vegetation occurs due to urbanization and intensification of industrial and agricultural production. More than 1900 rivers flow through the territory of the Saratov region, there are 3800 reservoirs, 32 underground water deposits and about 700 lakes. Their distinctive features include a small area, often-changing outlines and volumes. The sustainability of food production is increasingly ensured by the rational and efficient use of water resources and methods of their conservation, consisting mainly in the development and organization of irrigation, including the rational development of water resources for dry farming, water supply for livestock, inland fisheries and agroforestry. Achieving food security is one of the top priorities for many states, and agriculture should not only provide food for the growing population, but also contribute to resource conservation and efficient environmental management in various areas.
