摘要：
A controlled release fertilizer is provided which exhibits a Gaussian nutrient release rate pattern. The fertilizer composition includes a granular nutrient core material having a single layer coating of a substantially water-insoluble, uniform, substantially continuous polymer film thereon. Processes are also provided for producing the fertilizer compositions. Methods are also provided for treating plants with the fertilizer compositions.
