This article presents the results of a comprehensive study of the chemical composition, structural characteristics, and porous structure of soil and sand in the dried-out part of the Aral Sea. Chemical analysis of soil samples revealed a high content of basic elements, such as oxides of silicon, aluminium, iron, calcium, and magnesium, which affect chemical activity and interaction with the environment. The structural characteristics of the samples taken in the dried part of the Aral Sea made it possible to evaluate their ability to adsorb and interact with water and other substances. The study of soil's adsorption and porosity characteristics has revealed its ability to retain moisture and other important components in the porous structure. The results obtained allow us to better understand the mechanisms of interaction of soil and sand with water. Data can serve as a basis for developing effective and sustainable water management practices and optimizing the use of soil materials.
