PROBLEM TO BE SOLVED: To maintain safe and well-grown plants while effectively utilizing waste, and to maintain a shape-maintaining ability that can be expected to be highly effective as a long-term water preservative / purifier, and reusable charcoal / pH buffer adjustment Provide granular material mixed with agent. A resin, a plant material, and a salt compound are kneaded under a temperature condition of 300 ° C. or higher and within 400 ° C., and the kneaded product is pulverized to produce a charcoal / pH buffer adjuster kneaded granular material. By kneading at a high temperature of not less than 300 ° C. and not more than 400 ° C., the plant material is carbonized, and there is an advantage that the portion can have air permeability, water retention, adsorptivity and water pH adjustment function. By crushing and pulverizing the kneaded product, it becomes a preferable material for the growth environment of plants and aquatic organisms, and the kneaded product can be pulverized to 5 mm or less. As the resin, polypropylene, polyethylene, a synthetic resin typified by pet, and as the plant material, plant material typified by wheat straw, rice straw, rice husk, wood chips, and large sawdust can be used.
