Abstract

The agricultural land in the Republic of Uzbekistan is strategically classified into three key categories: irrigated lands, arable lands, and natural pastures. Currently, the Republic faces a diverse range of salinization levels on its irrigated lands. This article endeavors to establish a scientific foundation for the systematic distribution of irrigated soils across the provinces of Uzbekistan, taking into account the varying ecological conditions prevalent in the region. The primary focus of this article is on the analysis of soil samples derived from the Tashkent and Syrdarya provinces. A comprehensive examination is conducted, encompassing ecological, reclamation, agrochemical, and physical properties of these soils. By shedding light on these key attributes, the article aims to provide valuable insights into the overall condition of agricultural lands in Uzbekistan. Crucially, the article delves into the state of mineralization of groundwater and surface runoff, both essential components in irrigated agriculture. This analysis is pivotal in understanding the impact of these water sources on the plants cultivated in the region. Given the vital role of irrigated agriculture in Uzbekistan's food production, addressing the challenges posed by salinization and ensuring sustainable land management practices are imperative for safeguarding the agricultural sector's productivity and ecological balance. Through this scientific exploration, the article contributes to the broader understanding of the intricate interplay between soil properties, water quality, and successful agricultural practices in the Republic of Uzbekistan.
