FIELD: chemistry.
SUBSTANCE: invention relates to agriculture and is meant to produce granular organomineral fertiliser. The method involves batching components, grinding said components, mixing, granulation and drying. In order to prepare liquid additives from microelements, water is used, said water being treated with a constant magnetic field with induction 0.15-0.20 T and rate of flow of water in the treated gap of 0.9-1.1 m/s. Mineral additives are ground before mixing.
EFFECT: method ensures fast and efficient dissolution of trace elements in water, and also ensures more efficient dissolution and mixing of all components of the fertiliser.
