This invention relates to the art of fertilizers and, more particularly, to a coated granular fertilizer in which the dissolution rates of water-soluble fertilizer components are controlled by coating or encapsulating a granular fertilizer. The coating for the timed-release fertilizer is derived from plant cellulose extracted from hemp cellulose, sugar cane cellulose, or other plant-based cellulose.
