The ways of using collector drainage waters for irrigation

For the conditions of Uzbekistan, it is necessary to maintain reclamation condition irrigated lands constantly and increase soil fertility. It study land in our region. An important factor that collector-drainage waters are used for irrigation pay off shortage water resources. The object formed Republic Uzbekistan. article presents research on method statistical data processing, materials analysis, field research, computer plotting curves diagrams. As a result irrational use waters, secondary clogging observed some areas. Data analysis was carried out from 2005 2020. long-term studies shows by 2020 there decrease highly saline lands, which makes 83 thousand hectares. Whereas 2005, made up 160 Also, areas with different mineralization almost unchanged need develop scientifically based measures. purpose objectives scientific their impact state assess suitability irrigation. To reliability assessments quality under various natural economic conditions, recommended relationship between ratio chlorine sulfate. dependence built results hydrochemical regime waters. Estimates have shown at least 50% runoff suitable places formation Collector-drainage mainly sulfate type salinity, such 2-3 g/l, g/l can be repeated cover water, drainage increased diluting them fresh will also reuse.
