Abstract

A method for preparation of a nitro-complex fertilizer comprises steps of: acid hydrolysis reaction, neutralization reaction, and mixing process. The acid hydrolysis reaction comprises preparing 15 to 40 parts by weight of nitric acid, 4 to 10 parts by weight of phosphoric anhydride, 5 to 15 parts by weight of calcium oxide, and performing acid hydrolysis to obtain an acid slurry; the neutralization reaction comprises adding 2 to 25 parts by weight of sulfuric acid and 5 to 15 parts by weight of ammonia to the acid slurry to obtain an ammonia slurry; the mixing process comprises adding 15 to 40 parts by weight of potassium chloride to the ammonia slurry to obtain the nitro-complex fertilizer. The invention provides a nitro-complex fertilizer produced by the method above. The nitro-complex fertilizer contains calcium oxide, thereby decreasing activity of the ammonium nitrate for ensuring nitro-complex fertilizer safety during adding of organic matter.
