PROBLEM TO BE SOLVED: To provide a charcoal pH buffering adjusting mixing particulate material capable of expecting safe and good growth plants and high effect as a preservative/cleaning material of water for a long time of one year unit, having shape maintaining ability, and capable of being reused while effectively utilizing waste materials.SOLUTION: The charcoal pH buffering adjusting mixing particulate material is produced by mixing a resin, a plant material, and a salt compound under a temperature condition of not lower than 300°C and not higher than 400°C and crashing the mixture. There is a merit that the plant material is carbonized by mixing under the high temperature not lower than 300°C or and not higher than 400°C and it is possible to make the part have the air permeability, the water retaining property, the adsorbability, and the pH adjusting function of water. The material desirable to a growing environment of plants and aquatic organisms can be formed by crashing and pulverizing the mixture, and the mixture can be crashed to 5 mm or less. Synthetic resin including polypropylene, polyethylene, pet can be used as the resin and a plant material including straws, rice straws, rice husks, wood chips, saw dust can be used as the plant material. |
