Abstract
A solid nitrogen-containing fertilizer is obtained by treating an acidic material with a substantially neutral nitrogen compound dissolved in substantially anhydrous ammonia. The nitrogen compound is preferably ammonium nitrate and the moisture content is usually 0,2 to 0,8%. The acidic substance may be sulphuric acid, phosphoric acid, nitric acid, or an acid salts of superphosphate or triple superphosphate. Potassium chloride, ammonium nitrate, ammonium sulphate or urea may also be added. Reaction may be effected in a rotating drum mixer or in a TVA type ammoniator and the product is granular and does not set on storage.
