Investigation of Water Solubility of Soil Minerals in the Navbakhor District of Navoi Region

Abstract

The article delves into the application of IR-spectroscopic, chemical, and X-ray diffractometric methods to assess the mineralogical composition and salinity levels of soil samples collected from Navoi city and Navbakhor district, specifically the settlement of Shurkishlak. Through these studies, the researchers were able to discern the salinity characteristics of the region's old-irrigated soils.Findings indicate a predominance of carbonate salinity in Navoi city, while the Navbakhor district exhibits a notable prevalence of sulfate salinity, surpassing carbonate levels. Additionally, a third salinity type, characterized by chloride, is identified. Importantly, all observed soil minerals demonstrate varying degrees of water solubility, presenting in ionic form within aqueous soil extracts.These insights shed light on the soil composition and salinity dynamics of the studied regions, providing valuable information for agricultural planning and soil management strategies. Understanding the mineralogical composition and salinity profiles of soils is crucial for optimizing agricultural practices and ensuring sustainable land use in Navoi city and Navbakhor district.
