Altering a coloring raw material from a petroleum-derived one to natural resources is a consideration to the fear of the exhaustion of the petroleum raw material. Particularly a technique is provided which is useful in mixing in a raw material for an agricultural material containing a biodegradable resin. Even if a conventional general-purpose resin or a recycled resin is used as the base material, if a waste and the like such as wood is utilized as the raw material of the charcoal, it will lead to the effective use of resources.  <P>COPYRIGHT: (C)2008,JPO&INPIT
