<P>PROBLEM TO BE SOLVED: To provide an artificial soil improving material enabling simply easily performing without problem on safety, mineral supply and pH correction of artificial soil such as peat to be set on a rooftop of a building and an external wall. <P>SOLUTION: This artificial soil improving material comprises an fiber an aggregation made by making mainly minute glass fibers get entangled and having an average fiber diameter of 0.8-10 μm. The improving material enables equal supply of necessary mineral to plants and has an advantage of sustaining soil improving effect for a long period without causing scattering and outflow with wind and rain. As the improving material has a glass fiber material, the improving material unlike a plastic material, has weatherproofness of resisting to affects of ultraviolet rays and durability of enduring in setting for a long period. <P>COPYRIGHT: (C)2007,JPO&INPIT |
