Physical-Chemical, Geochemical Features and Their Impact of Soil-Ecological State of Hydromorphic Soils

Abstract: В статье приведено физико-химические и геохимические особенности и их влияние на почвенно-экологическое состояние орошаемых луговых сазовых почв Центральной Ферганы. Охарактеризованы педолитные горизонты с отрицательными водно-физическими и другими свойствами, которые являются результатом гидроаккумулятивных процессов в почвах пустынной зоны. Определено почвенный раствор и его свойства. Концентрация почвенных растворов в педолитных горизонтах изученных почв варьирует в пределах 4,1-6,2 г/л, что ниже, чем в поч… Show more

“…however, the simple salts affect the energetics state of soils and key physical, chemical, and biogeochemical soil properties. Also, various biogeochemical processes in soils are strongly affected by salts (komilov & isakov 1992;evett et al 2007;Turdaliev et al 2019b;kenjabaev et al 2020). There is a need to mention that the period of salinization harms the growth and yield of wheat in irrigated soils (Francois et al 1994;stringer et al 2010).…”

“…Fergana region of Uzbekistan (Figure 1), which has 563.7 thousand hectares of irrigated land, of which more than half is salinized to varying degrees and due to irrigation according to the leaching regime, as well as leaching of moderately and highly saline lands, a large volume of drainage, collector-drainage water is formed, which discharged into the Syrdarya rivers [11][12][13]. The chemical composition and mineralization of these waste waters, depending on soil and climatic conditions, especially the degree and quality of soil and groundwater salinization, is very different from river "ditch" waters [14].…”
