摘要：
The invention relates to a fertilizer granule containing ammonium nitrate, comprising a core containing ammonium nitrate and a coating layer containing calcium sulphate. The coating layer consists of a mixture containing calcium sulphate and ammonium nitrate. Such a fertilizer granule is preferably produced by contacting the core with an aqueous ammonium nitrate solution and solid calcium sulphate particles, either as a slurry or separately. The production of the fertilizer granule is safe and easy.
