摘要

FIELD: chemistry.;SUBSTANCE: invention relates to agriculture. The method of obtaining liquid mineral fertiliser based on industrial waste water from production of nitrogen-phosphorus-potassium fertilisers (NPK), which is characterised by that the industrial waste water is analysed and its composition is determined; the amount of substances ZnSO4·7H2O; MnSO4·7H2O; H3BO3; CuSO4·5H2O; (NH4)2MoO4; FeSO4·7H2O; Ca(H2PO4)2; MgCl2; KNO3 is determined, wherein when preparing the solution of the liquid mineral fertiliser, the substances are weighed, each is separately dissolved in a small amount of waste water; 200-300 ml of waste water is then poured into a 1 litre vessel and the prepared solutions are added successively while stirring; further, more waste water is added until obtaining a volume of 1 litre and then packaged; pH of the obtained liquid mineral fertiliser is in the range of 5.5-6; when watering plants, 50 ml of the fertiliser is dissolved in 1 litre of water.;EFFECT: invention ensures wasteless production, enables to recycle waste water, obtain liquid mineral fertiliser therefrom and use said fertiliser to grow plants in open and closed fields, as well as using hydroponic and ionitoponic methods.;2 tbl, 3 ex
