Abstract

The article presents the results of studies of the chemical composition of saline soils of irrigated arable land, which were previously part of hayfields and pastures in the foothill plain of the Almaty region. Here, on the territory of farms, violations of irrigation technology and cultivation of agricultural crops provoked the rise of saline solution in the root zone of plants, thus causing secondary salinization of soils. Studies have shown that northern light meadow sierozem soils transformed into solonchaks-solonetzes were distinguished by a chloride-sulfate type of salinization and solonetzization of the entire profile by absorbed sodium. The salt content in the middle part of the profile exceeded ≥1.5%. The concentration of the dominant sulfate ion in the upper horizon was 13.75 mg-eq, and with depth it increased to 19.50 mg-eq. The soil is not saline with soda, as evidenced by the absence and low content of carbonate and bicarbonate ions. The composition of absorbed bases is dominated by exchangeable sodium, which occupies from 34.0 to 40.5% of the share of the cation exchange capacity. The data obtained are valuable in that they show the state of anthropogenically degraded saline lands of temporary irrigated lands, which require further comprehensive study based on ground and space methods and approaches.
