the article presents the results of studies of the geological structure of soils and methods of water resources management. From a geological point of view, the massif of the Asa River belongs to the complex of modern alluvial-proluvial deposits, contributes to their complex relationship in size and area, lithological differences [1]. In the valley of the Asa River, hydromorphic soils developed, influenced by shallow mineralized groundwater [2, 3]. The soil cover of desert areas consists of loose gray soil. Meadow-serozem irrigated loamy sandy soils, the parent rock is sandy loam, the bedding is sand [4]. The main source of irrigation for plants in the Asa river basin is surface water. However, during the growing season, there is an annual shortage of irrigation water; over the years of research, the water supply for 1 ha of irrigated land in the Zhambyl region was 3561-5988 m3/ha. The analysis of the water balance shows that irrigation along furrows increases the loss of water, the consumption of which is 2100 m3/ha [5]. When irrigating through the furrow, losses for consumption reduced to 600 m3/ha, i.e. 29% higher than furrow irrigation. Water-saving technology of irrigation through the furrow will allow: to reduce the size of water intake for irrigation to 15-35%; reduce economic costs; will increase the yield of agricultural products.
