METHOD FOR PRODUCING beznitratny liquid complex fertilizers based on ammonium nitrate (OPTIONS)

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to agriculture. The method of producing liquid compound fertiliser, which involves mixing ammonium nitrate solution with a carbonic acid derivative, the ammonium nitrate used being an 80% solution of ammonium nitrate before the evaporation step, and the carbonic acid used being magnesium carbonate, wherein components are mixed in ratio of 1:0.525 while stirring continuously at temperature not higher than 55°C, and pH of the solution is brought to 7.;EFFECT: invention increases nutrient value and reduces the cost of producing ammonium nitrate-based fertiliser.;5 cl, 5 ex
