LIME NITROGEN GRANULAR FERTILIZER AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To provide a lime nitrogen granular fertilizer having high hardness to suppress powdering in storage and high cyanamide content. SOLUTION: The lime nitrogen granular fertilizer is granulated with saccharide and has ≥30 mass% powdering residual ratio. It is preferable that the powdering residual ratio is ≥50 mass%. the saccharide is at least one kind selected from sucrose, lactose and glucose, the content of the saccharide is 2-20 mass%, average hardness is 5-15 kg/piece and the powering residual ratio is ≥80 mass%. The method of manufacturing the lime nitrogen granular fertilized is carried out by granulating a powdery mixture of raw material powder of the lime nitrogen fertilizer with the saccharide and heating at a temperature equal to or higher than the melting point of the saccharide.
