Abstract
A method of producing a fertilizer composition containing micronized sulphur wherein elemental sulphur is dissolved in anhydrous or hydrous ammonia to form an ammonia/sulphur solution and the ammonia/sulphur solution is reacted with an acidic component having at least one plant growth constituent to simultaneously form a sulphur composition comprising a sulphur compound and micronized sulphur. The thus formed fertilizer composition is dried and can be formed into various shapes such as pellets, prills, etc.
