Technical and technological Solutions for environmentally safe Irrigation with wide-reach Sprinklers

Abstract

It is known that sprinkling can cause surface runoff of irrigation water and water erosion of soils, which leads to deterioration of water-physical and agrochemical properties of soils, its fertility decreases. The purpose of the research was to ensure environmentally safe irrigation with wide-reach sprinklers by improving the designs of sprinklers and their placement along the pipeline. The developed sprinklers were equipped with sprinklers “Frigate” DMU-B463-90. Studies have shown that the volume of surface runoff of irrigation water during the irrigation season when watering with sprinklers with developed sprinklers was less, and as a percentage of the irrigation norm was: in 2020, when watering DM with sprinklers having a rotating deflector – 6.3%, when watering with a machine with sprinklers having a double deflector – 3.9%; in 2021 respectively – 6.6 and 4.1%, in 2022 – 6.0 and 3.9%. The conducted studies allowed us to recommend installing sprinklers with a rotating deflector or cascade versions at high irrigation rates in the end part of the machine.
