“…The maximum toxic effect is shown by soda, then chloride, then sodium and magnesium bicarbonates, as well as magnesium and sodium sulfates. Gypsum, as well as calcium carbonate, is not poisonous (unlike toxic magnesium carbonate), however, its presence in increased quantities (gypsum bark) leads to a decrease in the overall fertility of the soil [2,3].…”

“…This leads to the processes of physical degradation of soils, which serves as a trigger in the development of stages of ecological crisis and natural disasters in ecosystems. The general increase in saline soil areas and the reduction of arable land causes an urgent need for monitoring and environmental assessment of the ecological state of irrigated soils [2,3].…”

The article presents the results of studies of various types of soils in arid territories. Due to the increased intensity of anthropogenic impacts on ecosystems in many regions, large-scale soil salinization is singled out as one of the factors in the development of soil degradation processes. The depth of occurrence, mineralization and chemical composition of groundwater are subject to seasonal, annual and long-term changes, which can be described by certain patterns of hydro regime. The development of secondary salinization in the region can be attributed to the existing problems that have arisen as a result of the widespread development of irrigation. The solution of this issue requires the development of new approaches to the development of irrigation in the Southern Aral Sea region.

“…Over the past three years, the same crop (cotton) should be sown on a key plot. The size of the key site and the amount of work on it are determined by the degree of complexity of the soil-salt conditions, reflected on the materials of the APS and KFS [14,15,16].…”

The proposed methodological recommendation on the ground support of remote methods for assessing salinization of soil in reclaimed lands is devoted to the operational monitoring of salinity of reclaimed lands. The assessment and forecasting of cotton yield in the Hungry Steppe and the lower reaches of the Amu Darya, by direct signs of determining salinity at farms, a separate irrigated plot, based on remote information (aerial and space photography - APS and KFS). The task of the under investigations study is visual assessment of soil salinity level by indirect signs: condition of crops, fall of plants, salt bloom, etc. The results of the established check are recorded in the field journal. Salinity map with salinity contours; slightly saline, moderately saline and strongly saline soils are created based on the studied research materials. Number and location of the main sites for determination of soil salinity features are determined on the basis of analysis of the research materials determined with involvement of other available materials on the soil cover characteristics. Classification of soils according to the degree of salinity is carried out according to the formula WP = PVU + VJp; WP = 51.42 - 96.28 Jp ± 1.12 g ha-1. It is presented in Table 2 for Amu-Darya lower reaches (Khorezm province and the Republic of Karakalpakstan), where + Y - yield calculation; PVU - maximum yield. This program is designed for use in the educational process during practical lessons on agricultural reclamation directions.

“…Some researchers believe that in the Far East and the Krasnodar Territory conditions, periodic drainage and irrigation in checks reduce rice yield compared to constant flooding. In our opinion, conflicting opinions about the timing of flooding of rice crops during the growing season are associated with climatic conditions and biological characteristics of varieties, various rice cultivation technologies, and research methodology [8].…”

The article presents the results of field studies on the application of sprinkling and drip irrigation technologies in the cultivation of rice in the soil and climatic conditions of the Republic of Karakalpakstan based on the tasks defined in the Decree of the President of the Republic of Uzbekistan dated February 2, 2021, No. PD-4973 "On measures for the further development of rice growing". This article presents the results of field and laboratory studies on the application of rain and drip irrigation technologies in the cultivation of rice, primary irrigation regimes suitable for the soil and climatic conditions of the research object, the mechanical composition of the soil, salinity levels, salinity of irrigation water and the use of water-saving technologies in the cultivation of rice in experimental versions. The influence of the hydrochemical state of water on the soil and the yield of rice and its quality indicators were determined in the field conditions of the experiment.
