FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Method of producing organomineral fertilizer is characterized by that it includes treatment of sewage sludge with solution of nitric acid, neutralization of acidity of sewage sludge with an alkaline agent, subsequent grinding, wetting, magnetic separation of sewage sludge, mixing of treated waste water with mineral additives, placed in at least two supply silos, in each of which additives are subjected to aeration, after which mixture granulation and packing are performed, at that, after granulation one performs instant analysis of the ingredients and mixture quality, according to the results of which the volume of each of the ingredients is determined using an automated analytical control system depending on the fertilizer formula and using the automated process control system, the silo with additives valves are opened.
EFFECT: invention widens range of organomineral fertilizers.
