摘要：
A controlled release fertilizer including a fertilizer granule, having an outer surface, a coating of biopolymer composition on the outer surface of the fertilizer granule, wherein the biopolymer composition includes at least one biopolymer, and a process of making the controlled release fertilizer including the steps of screening fertilizer granules to a preselected granule size, heating a biopolymer to become substantially fluid, and applying the biopolymer onto the surface of the fertilizer granule to produce a coating on the granule of a predetermined amount.
