FERTILISING COMPOSITION OF CONTROLLABLE ACTIVE INGREDIENTS RELEASE AND METHOD OF OBTAINING SAME

摘要

A controlled release fertiliser composition is provided having a fertiliser compound in a granular core with a coating applied on the core material. The fertiliser composition is structured to enable a cumulative release of fertiliser compound of less than 10 % of the total weight of the fertiliser compound in the granular core within 30 days after exposure of the fertiliser composition to moisture and the coating consists of a single layer of a uniform, substantially continuous polymer film which is present on at least 90 % of the granular core material. A process is also provided for producing the fertiliser composition.
