Abstract: The solubility of granule-type fertilizer is controlled by coating it with the solubility-controllable compound. The coating compound is manufactured by mixing or by reacting the rosin 50-100 wt.%, water-insoluble metal compound 0-10 wt.% such as aliphatic compound of aluminum, calcium, copper, magnesium or zinc or silicofluoride of calcium or lithium or rosin-reactive alkaki earth metal, and high polymer 0-50 wt.% such as paraffin wax, ethyl cellulose, benzyl cellulose, alkyd resin, phenol resin, or PVC.
