Technical justification of the application of double regulation of ground water level (sub-irrigation) in the conditions of the republic of Karakalpakstan
Abstract
The article contains proposals for double regulation of the groundwater level to obtain a high yield with the lowest water consumption. In the article, all side-by-side studies of the issues of double regulation of the groundwater level and scientifically-based proposals are given on them. The report contains the results of studies carried out at experimental sites in the Khojaili region and Kungrad regions of the Republic of Karakalpakstan. According to the data of the conducted field studies on the collector, the calculated parameters were obtained for double regulation by the construction of retaining structures. During the growing season, the collector was locked, and the optimal soil moisture was achieved and, accordingly, the yield of agricultural crops was increased.
