manufacture of fertilizers. SUBSTANCE: original working concentrated copper-ammonia solution containing, as main components, copper tetraammoniate acetate, ratios of components being as follows, wt %: copper in complex salt, 16.7; acetic acid, 23.86; ammonia, 13.86; and water, the balance is diluted or added to micro fertilizers to attain copper content in final product within 0.01-0.30 wt % to prepare copper-containing simple and complex micro-and macro fertilizers. Method does not require using complex technologies, makes it possible to prepare effective copper containing simple and complex micro-and macro fertilizers and to attain ecological safety and high efficiency of utilization of copper ammonia solution in divinely production. Said fertilizers are dangerous during storage period. EFFECT: more efficient utilization method. 4 ex |
