Abstract

A novel granular fertilizer encapsuled with a decomposable coating, the coating comprising a vinyl resin containing at least one type of metal complex. The dissolving period of the fertilizer of the present invention does not change drasti-cally in any cultures, and after the components of the fer-tilizer dissolves, the coating degrades and decomposes under natural environmental conditions.
