FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Ammonia-based fertilizer based on carbamide and ammonium nitrate contains ammonium sulphate at weight ratio of nitrogen to sulfur equal to (29-23):(1-3) and additional substances: caprolactam in amount of 0.01-0.15 wt% and stabilizing additive in amount of 0.1-0.7 wt%. Fertilizer is obtained by mixing with the help of pump and circulation circuit of aqueous solution of ammonium sulphate with concentration of 38-42 wt% and pH equal to 6-8, containing caprolactam, with aqueous solution of carbamide, ammonium nitrate and stabilizing additive.
EFFECT: invention increases yield of agricultural crops.
