Integrated approach to enhancing irrigation efficiency through water-saving technologies and regime adjustment: evidence from the Kurty irrigation massif

The conducted research and analysis of hydro-reclamation systems operation experience demonstrate that the share of groundwater in the total water consumption of agricultural crops directly depends on the depth of their occurrence and the degree of mineralization. When groundwater is close, it is especially important to strive to reduce the volume of irrigation rates. This reduces irrigation water losses, ensures more rational water use and increases the efficiency of water resources use in irrigated areas. The article considers the problems of irrigation in the Kurtinsky massif and presents the results of calculations of irrigation regimes for various levels of water availability (50, 75 and 95%). A comparative analysis of calculated and actual data on water consumption was carried out, which revealed a significant overrun of water and a low efficiency of the irrigation system. The factors affecting the efficiency of water resources use, including technical, organizational and economic aspects, are discussed. Recommendations are given for optimizing irrigation regimes and implementing water-saving technologies. The necessity of taking into account the influence of the level and mineralization of groundwater on the yield of agricultural crops is emphasized. The conclusion is made about the importance of an integrated approach to water resources management to ensure sustainable agricultural development.
