Although bamboo is a herbaceous plant, it shares many characteristics with wood, making it a versatile material for various timber applications. Its rapid growth rate also makes it an ideal species for bio-circular forest establishment, adding to its afforestation value. As the climate warms, bamboo's growing range is expanding, and its role as a carbon sink is increasing due to its fast growth. However, after harvesting bamboo's culm parts, a large amount of branches and leaves remain, which have limited uses and incur significant costs for disposal. A potential solution to this issue is to propose utilizing of bamboo by-products, which are produced in large quantities on-site, as ash. The ash of the plant contains many inorganic nutrients. This study analyzes the nutrients contained in the ash from bamboo by-products (branches and leaves), and investigates its effects on plant growth. We evaluated the usability of ash recovered after incinerating (500℃<) bamboo (Phyllostachys pubesens) by-products. The analysis revealed that the incineration ash contained high concentrations of potassium (>80,000 ppm), calcium (>50,000 ppm), phosphorus (>20,000 ppm), magnesium (>20,000 ppm), manganese (>10,000 ppm), and iron (>10,000 ppm), with aluminum, sulfur, sodium, and silicon also identified as major elements. In the plant growth evaluation, the survival rates of Alnus incana were similar across all treatments (94%-100%), but root induction decreased in the ash-treated group. In contrast, the survival rate of Rhododendron mucronulatum was lower in the ash-treated groups, and no root induction occurred. A. incana adapts well to a wide range of soil pH, while R. mucronulatum typically thrives in acidic soils. The high cation content of the ash likely increased the pH of the medium, affecting the growth of R. mucronulatum. Based on these results, future studies will focus on selecting appropriate plants and adjusting concentrations and pH levels to further assess the potential of bamboo by-product ash as a soil fertilizer. Through these efforts, we aim to minimize the environmental impact of bamboo by-products and maximize their practical value as a renewable resource.
