FIELD: agriculture.
SUBSTANCE: method of preparing water for irrigation, which comprises processing of the primary water in the cathode chamber of the first diaphragm electrolyser and mixing it with the product of processing the solution in the anode chamber of the second diaphragm electrolyser, at that the primary water is used as the purified fresh water, the solution of phosphoric or nitric acid or their mixture is fed for processing to the anode chamber of the second electrolyser, and the processing in the cathode chamber of the first electrolyser is carried out to a pH of 9.5-10, and the processing in the anode chamber of the second electrolyser is carried out until increase of initial redox potential of the acid solution at 200-400 mV relative the chloride silver reference electrode.
EFFECT: invention enables to simplify the process of preparation of water for irrigation.
