本レビューは、バイオチャー施用による土壌炭素隔離のメカニズム（物理化学的安定化、微生物相互作用、有機-鉱物結合）を詳述する。バイオチャーは気候スマート農業や廃棄物管理に有望だが、原料の不均一性、経済性、長期データ不足が課題である。今後の研究としてバイオチャー工学、LCA、政策統合が挙げられる。
English
This review examines the mechanisms of biochar for soil carbon sequestration, including physicochemical stabilization, microbial interactions, and organo-mineral associations. Biochar shows promise for climate-smart agriculture and waste management, but challenges remain in feedstock heterogeneity, economic viability, and long-term field data. Future research directions include biochar engineering, life cycle assessment, and policy integration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、バイオチャーは農地での炭素貯留手段として注目され、土壌改良と気候変動対策の両面で期待される。ただし、コストや長期効果の実証データ不足が普及の障壁であり、国内での実証研究やJ-クレジット制度との連携が重要である。
In the global GX context
Globally, biochar is recognized as a key negative emissions technology (NET) in IPCC pathways. This review offers a comprehensive mechanistic basis for integrating biochar into carbon markets, agricultural policies, and corporate net-zero strategies, addressing both opportunities and barriers.
👥 読者別の含意
🔬研究者:Provides a mechanistic foundation for biochar research, highlighting knowledge gaps and future directions.
🏢実務担当者:Useful for agricultural companies considering biochar for soil health and carbon credits.
🏛政策担当者:Informs design of carbon removal policies and inclusion of biochar in carbon markets.
📄 Abstract（原文）
Soil carbon sequestration has now become a key approach to reduce the effect of climate change and maintain soil fertility and agricultural sustainability. Among several treatments, biochar application has attracted increasing attention as a method to sequester carbon in soils over centuries to millennia. Biochar is a carbonaceous material produced by the thermochemical processing of biomass in an oxygen-limited environment. In addition to its chemical structure, biochar has unique physical and chemical characteristics such as high porosity, surface area, and oxygen containing functional groups which contribute to enhanced soil quality and long-term carbon sequestration. This review provides an in-depth analysis of how biochar enhances soil carbon sequestration through physicochemical stabilization, interactions with microbes, and associations with organo-mineral matter. Further, it presents promising potential of biochar in climate smart agriculture and waste management, soil fertility improvement and ecosystem recovery. Yet limitations such as the heterogeneity of feedstock, variable field results, economic considerations and insufficient long-term field data, need to be addressed for widespread implementation. The review also highlights potential future research areas such as biochar engineering, life cycle assessment and policy integration. Taken together, biochar is a promising soil carbon lever for maintaining sustainable soils and mitigating climate change.
