Abstract

The invention relates to a special resin-coated controlled-release fertilizer used for a lawn and a manufacturing method thereof. The special fertilizer is made by compounding 6 per cent thermoplastic resin-coated potassium nitrate, 7 per cent thermoplastic resin-coated ammonium phosphate, 6 per cent thermoplastic resin-coated diammonium phosphate, 7 per cent thermoplastic resin-coated diammonium phosphate, 4 per cent thermoplastic resin-coated urea, 5 per cent thermoplastic resin-coated urea, 6 per cent thermoplastic resin-coated urea, 7 per cent thermoplastic resin-coated urea 8 per cent thermoplastic resin-coated urea, potassium chloride compound fertilizer, etc. The special controlled-release fertilizer used for a lawn of the invention is manured once in October every year and the dressing is avoided.
