USE OF MINERALIZED WATERS FOR IRRIGATION OF THE TERRITORY OF UZBEKISTAN

Abstract

Justification and development of anti-subsidence measures for the use of furrow irrigation Annotation: The first two years, experimental fields of 4 hectares were prepared to study the technique of irrigation along furrows with one-time on medium-sagging and two-time compaction of the bottom furrows with the wheels of the T-28x4 tractor according to a specially proposed scheme (Fig. 1). The main purpose of this experiment is to determine the possibility of reducing water absorption into the furrow and, consequently, to reduce the depth water loss, to reduce the roughness of the furrow to accelerate the flow of the jet to the end of the furrow, which would make it possible to maintain the uniformity of the distribution of subsidence along the length of the field and reduce the influence of individual local subsidence on the process of water absorption into the soil. The next stage of work was the following activities.
