The technology of fertilizing irrigation with differentiated norms using wide-reach sprinkler machines

Abstract

Fertigation shows its high efficiency, but requires careful dosing of mineral fertilizers and irrigation water. The aim is to improve the technology of irrigation with wide-coverage sprinklers when applying fertilizers with irrigation water. The article presents the technology of differentiated irrigation with the introduction of fertilizers. A method for determining irrigation standards is given, taking into account changes in soil moisture reserves, including during reverse movement. A fertilizer dispenser is presented with the calculation of the dosage of fertilizer application in accordance with the irrigation rate. When using differentiated technologies, the yield of Moskovskaya wheat increased by 45% compared to traditional technology (uniform irrigation rate).
