本研究は、岩石粉（リミネラライザー）が大気中のCO2を捕捉し、土壌肥沃度を向上させる可能性を評価した。5種類の岩石を粘土質赤色酸化土に施用し、有機物との相乗効果によりpHが5から7に上昇し、作物の成長が改善された。この結果は、地域の鉱物資源と有機改良材の統合が、持続可能な農業と炭素隔離に貢献することを示唆している。
English
This study evaluates ground silicate rocks (remineralizers) for CO2 capture and soil fertility enhancement. Experiments with five rock types on clay soil showed that combined with organic matter, pH increased from 5 to 7, boosting crop growth. The findings suggest integrating regional mineral resources with organic amendments offers a sustainable alternative for agriculture and carbon sequestration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策では、ネガティブエミッション技術としての炭素除去が注目されており、本研究成果は、国内の農業土壌や未利用鉱物資源を活用した炭素貯留の可能性を示唆する。ただし、日本の土壌条件や気候との適合性については追加検証が必要。
In the global GX context
This paper contributes to the global discourse on enhanced weathering as a carbon dioxide removal (CDR) strategy, relevant to IPCC scenarios and net-zero targets. It provides empirical evidence on the synergy between rock dust and organic matter, offering a scalable approach for agricultural carbon sequestration that could be integrated into national CDR policies.
👥 読者別の含意
🔬研究者:This study provides experimental data on enhanced weathering effects on soil chemistry and crop yield, useful for carbon removal and sustainable agriculture researchers.
🏢実務担当者:Farmers and agribusinesses can consider integrating locally available rock dusts with organic amendments as a cost-effective alternative to synthetic fertilizers.
🏛政策担当者:Policymakers exploring CDR options should note the potential of rock dusts for soil carbon sequestration and agricultural resilience, though scaling requires further validation.
📄 Abstract（原文）
Addressing climate change and food security, this article evaluates ground silicate rocks (remineralizers) as tools for atmospheric CO2 capture and food and nutrition security. The experiments were conducted under controlled conditions using leaching columns, to quantify the leached carbon and pots, to evaluate the growth and nutrition of three agricultural crops. Five rock types (basalt, kamafugite, chlorite–muscovite calc–schist, hydrothermalized calc–silicate, and biotite–actinolite schist) were applied to a clayed Red Oxisol (S) at 20 t ha−1, with and without organic matter (OM) at 40 t ha−1. The study involved 84 experimental units, including S, S + R, S + OM, S + R + OM, and S, S + OM and NPK controls. The results demonstrate that R + OM synergies significantly improved soil chemical properties, raising pH from 5 to 7 and increasing electrical conductivity. These amendments enhanced the growth and mineral content of beans, arugula, and carrots compared to conventional NPK formulations. While OM influenced overall carbon mobility, the specific contribution of silicate minerals to carbon dioxide removal (CDR) was most evident in S + R treatments. The findings suggest that integrating regional mineral resources with organic amendments offers a scalable, sustainable alternative to synthetic fertilizers, fostering resilient agricultural systems while contributing to global carbon sequestration targets.
