摘要： Granulated water-soluble calcium-nitrous fertilizer is prepared by decomposition of mineral salts having calcium cations with nitrous acid and by processing of the accrued melt. After the decomposition of the mineral salts having calcium cations with use of the nitrous acid, the undesirable cations Fe3+ and/or Mn2+ are precipitated from the reaction mixture, the precipitate is separated, and the molar ratio of Ca2+ : NH4+ is adjusted to a value from 4.5 to 9.4 through adding of water solution of nitrous acid and/or ammonia and/or ammonium nitrate. The solution warmed to the temperature from 100 to 170 °C is injected into a granulator, where recycled product obtained in the process of its preparation is supplied. The granulation is led at temperature from 40 to 135 °C, the temperature of accrued granulate is set to a value not exceeding 110 °C, the granulated material is divided by sieving into sub-sieve fraction, production fraction and over-sieve fraction; the over-sieve fraction is grinded and they are returned together with the sub-sieve fraction into the granulator as the recycled product.
