A fertilizer composition manufactured by mixing a fertilizer or a fertilizing substance with pullulan or a derivative thereof, used as binder, and solidifying the mixture. The composition is easily shapable. Another advantage of pullulan over conventional binders is that the pullulan or its derivative which remains in the soil after application of the composition and dissolution of the fertilizer component is degraded by the action of water and soil microorganisms in the soil and, hence, will not hinder the growth of plants.
