“…Kutsokon [21]. The authors used halophytic plants in experiments and proved their effectiveness in combating erosion and deflation of soils, which contributed to an increase in the productive potential of crops [22][23][24][25]. Thus, there is a need for further research and development of various technologies for the restoration of degraded soils, not only with the regulation of the groundwater level but also in combination with agrotechnical, chemical, biological, and other types of land reclamation.…”

The purpose of the work was to substantiate and develop technologies for the desalinization of soils by regulating the level of groundwater. The research methodology included field experiments, laboratory analyzes and mathematical calculations using formulas. The ecological and reclamation zoning of the studied massif in the Bayzak district of the Zhambyl region of Kazakhstan was carried out by the research team. A study of the hydrophysical characteristics of soils showed that 25% of the lands were non-saline, 33.3% were highly saline, and 41.7% were moderately saline soil varieties. The article presents the results of improving the efficiency of washing and watering soils using various technologies for water supply, as well as chemical reclamation elements such as phosphogypsum and manure application. It has been established that it is possible to regulate groundwater when drains are cut at a distance of 100-125 m from each other when they are located at a depth of 3 m, and the alternation of drains of different configurations using a greenhouse-type structure ensures the flow of water purified from salts through condensation into the soil. Deep loosening and the introduction of phosphogypsum and manure increased the leaching capacity of soils by 2.0-2.5 times and also accelerated the outflow of leaching fluid by 33-40%. The studied technology for the restoration of degraded soils made it possible to reduce the leaching exposure by 2.5 times compared to the traditional method. Thus, in this paper, the principles of flushing saline soils with the help of groundwater regulation were substantiated.

For the development of measures for the rational use of soils, an agrochemical assessment of soils is important. The purpose of research was to establish the dynamics of changes in soil fertility indicators of the Chernivtsi region during 2011-2020. In our work were used laboratory and field methods, analysis and generalization. In the soil samples, the reaction of the soil environment, humus content, nitrogen content of easily hydrolyzable compounds, mobile phosphates and exchangeable potassium were determined. It was established that the acidity of the soil solution in the region is dominated by lands close to neutral (31.8%) and neutral (36.5%). The weighted average indicator of saline pH is 5.8, which corresponds to a close to neutral reaction of the soil solution. Compared to the previous survey round (2011-2015), the weighted average pH did not change. In terms of the level of humus provision, soils with an average humus content prevail (66.7%), and the weighted average humus content in the region is 2.7%. Compared to the previous survey round, the weighted average content of humus increased by 0.1%. According to the content of easily hydrolyzable nitrogen, most lands have very low (48.3%) and low nitrogen content (48.7%). The weighted average indicator of easily hydrolyzable nitrogen content for the reporting period is 106.4 mg/kg of soil, which corresponds to the low availability of this element. When compared with the previous survey round, the weighted average indicator of easily hydrolyzable nitrogen content increased by 0.9 mg/kg of soil. The region is dominated by lands with an average content of mobile phosphorus compounds (31.5%), and the weighted average indicator of the content of mobile phosphorus compounds is 56 mg/kg, which corresponds to average availability. Compared to the previous survey round, the weighted average indicator of phosphorus content increased by 4.0 mg/kg. In terms of the content of mobile compounds of potassium, lands with a very high content of potassium prevail (51.5%), although the weighted average indicator of the content of mobile compounds of potassium is 78 mg/kg, which corresponds to the average supply of the macroelement. Compared to the previous survey round, the weighted average indicator of phosphorus content increased by 15.4 mg/kg. The results of the article can be used in the process of training specialists in soil science and agronomy, and will also be useful for land users of the Chernivtsi region when planning measures for the rational use of soils.
