Abstract
The article gives a brief description of the economic activity on the Karatal irrigation massif. The factors influencing hydrogeological-meliorative and soil-meliorative conditions, the formation of level and hydrochemical regimes under the influence of irrigation are considered in order to identify the main patterns. Presented the results of observations, the conditions of land salinization are generalized and analyzed. Based on the analysis of the groundwater regime, the degree of soil salinity, information is provided on the areal distribution of groundwater by depth and mineralization, according to which the assessment of the reclamation state of the irrigated lands of the massif is given. On the basis of the performed assessment, recommendations for its improvement are given, since the study, assessment and control of the hydrogeological and meliorative condition of irrigated lands are necessary for the justification and implementation of measures that ensure favorable water and salt regimes, as a result of increasing the yield of agricultural crops.
