Abstract
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.
Claims34
A fertilizer composition comprising a fertilizer or a fertilizing substance and pullulane or a derivative thereof.
A fertilizer pile comprising a fertilizer or a fertilizing substance and pullulan or a derivative thereof.
A process for producing a fertilizer composition which comprises mixing a fertilizer or a fertilizing substance and pullulan or a derivative thereof and granulating or compression-molding the resulting mixture.
A process for producing a fertilizer pile, which comprises mixing a fertilizer or a fertilizing substance and pullulan or a derivative thereof and extruding them through a die of an extruder at a temperature higher than that at which pullulan becomes plastic but lower than the decomposition temperature of the fertilizer.
