Water conservation in the reclamation of saline irrigated lands of Uzbekistan

On the territory of Uzbekistan, almost half area irrigated land is subject to salinization, for this reason up 30 % or more crop yield lost. With a shortage water resources, which will deepen due climate change, water-saving technologies must be used not only irrigation but also reclamation saline soils. The authors have developed new approach regulation salt regime and soil reclamation. conducted experiments established that use Biosolvent preparation doubles efficiency washing lands, increased leaching salts. To reduce salinity by 0.1% total amount salts, unit costs are 610 m3/ha. Calculation on basis field experimental data from 2016 (of indicators removal when using Biosolvent), shows reduction norm 3000 m3/ha 38 %, at transition soils “strong” degree salinization “non-saline”. study 2020 proved application melioration highly gypsum soils, combined with their preliminary deep loosening, allows reducing 5 dS/m, atmospheric precipitation.
