Assessment of the ecological state of salinized lands on the territory of Kazakhstan.

One of the main concerns of the modern era is the growth of saline soils in Kazakhstan. Scientists are becoming increasingly interested in land degradation, including the spread of saline soils. Kazakhstan's soil cover has been significantly impacted by contemporary ecological issues, which are primary due to excessive human activity and the inappropriate usage of natural resources. In all of the Republic's natural zones, the state of the soil cover has gotten worse due to the ecological condition being unstable. The Republic spans a total area 272 million hectares, of which 222 million hectares are used for agriculture, including 27 million hectares are arable land. Unfavorable ecological conditions have emerged on the Republic's agricultural fields. The southern regions of Kazakhstan experience a climate characterized by extreme drought, which leads to the prevalence of unsuitable soil cover in these areas. According to the scheme of natural and agricultural zoning of the land fund of the Republic of Kazakhstan, the region of deserts within the structural and accumulator plain of the Northern Aral Sea region is composed of the districts of Syrdarya and the Aral Sea. A map of soil salinization on the territory of Kazakhstan was made, which indicates that saline soils cover approximately 85% of the land area in Kyzylorda region (20.3 million hectares) out of a total of 22.6 million hectares of saline soils. Cartographic materials on Kazakhstan's salinized soils were taken under consideration for this study. It was discovered that Kazakhstan's central and southern regions are largely covered in saline soils. [ABSTRACT FROM AUTHOR]
