The purpose of the study is to analyze the effectiveness of the technology of irrigation water quality of Ingulets Irrigation System (IWS), which will improve water quality and reduce its load on the ecological and agro-ameliorative condition of irrigated lands with further increase of crop yields in modern ecological, economic and water conditions. It is established that the variant of formation of quality of irrigation water - "Washing of the river Ingulets from the Karachunovsky reservoir in the vegetation period", provides formation of quality of water of the II class "limitedly suitable" in the vegetation period. With the introduction of a new variant of water quality formation of the Ingulets irrigation system - flushing from above for the entire irrigation period (rejection of the "anti-river"), the application of which forms a stable satisfactory water quality at the source of irrigation of the Ingulets River during the entire vegetative period. from the Karachunivsky reservoir in the period from April 15 to September 15 with a volume of not less than 190 million m3 and costs not less than 12 m3/s with adjustment depending on climatic and weather conditions of the year. In general, the quality of ISS water can be characterized by class II quality of irrigation water. When generalizing the average long-term data of water quality at MK IZS, a model of the chemical composition of irrigation water during the irrigation period of the year was obtained, as well as a model of the dynamics of the hydrochemical regime of the Ingulets River. Irrigation water ISS is characterized as medium-mineralized, long-term mineralization of 1.5-1.6 g/dm3, pH = 7.6.
According to the results of the research, the optimal technology of formation of irrigation water quality of Ingulets irrigation system is proposed, which will improve water quality and reduce its load on the ecological and agro-ameliorative condition of irrigated lands.
