Abstract
A fertilizer composition in the form of granules having a size of 0.25-7 mm. is produced by mixing finely ground phosphorus-containing basic slag, 10-100% of potassium chloride or sulphate based on the slag, at least 2% of another fertilizer based on the slag and potassium compound, and up to 50% of water based on the slag and potassium compound. The composition may contain 2-12% of magnesium oxide, chloride, carbonate or sulphate, or 2-45% of urea.
