本レビューは、土壌有機炭素（SOC）が作物生産性と農業生態系の回復力に与える影響を、長期圃場試験の証拠に基づいて検討する。SOCと収量の正の関連は認められるが、その効果は土壌・気候・管理に依存し、炭素隔離と農業上の利益の間にトレードオフがある。文脈に応じたSOC管理戦略の必要性を強調している。
English
This narrative review synthesizes evidence from long-term field studies to examine the role of soil organic carbon (SOC) in crop productivity and agroecosystem resilience. While SOC is positively associated with yields, the response is context-dependent and slow, with trade-offs between carbon sequestration and agronomic benefits. The authors advocate for context-specific SOC management strategies beyond simply increasing carbon stocks.

日本のGX文脈において
日本では、農地土壌への炭素貯留はみどりの食料システム戦略やJ-クレジット制度と関連するが、本論文は具体的な政策連動に欠ける。日本の農業関係者にとっては、土壌炭素管理の科学的背景を理解する上で参考になる。
In the global GX context
Globally, soil carbon sequestration is recognized as a climate mitigation strategy, but this paper highlights the complexities and context-dependence of SOC management. It contributes to the discourse on sustainable agriculture and climate-smart practices, though it does not directly address corporate disclosure or transition finance.

📄 Abstract（原文）
ABSTRACT Soil organic carbon (SOC) is central to soil health, crop productivity, and agroecosystem resilience because of its influence on soil physical, chemical, and biological properties and processes. However, increasing SOC does not uniformly improve crop productivity, as SOC responses to management are often slow and the resulting agronomic benefits depend on soil, climate, and management context. In this narrative review, we synthesize evidence from arable field studies without constraining geographic boundaries to examine SOC‐associated soil processes, long‐term SOC changes under agricultural management, and relationships between SOC content and crop yield. Nine long‐term field studies spanning diverse geographic and climatic regions were used to summarize changes in SOC over time under contrasting management practices. To explore SOC‐yield relationships, studies reporting both SOC and yield were compiled from long‐term field studies of corn and wheat as examples. Across these studies, SOC content was positively associated with corn and wheat yields, although the strength of these relationships varied and likely reflected interactions among soil, climate, cropping systems, and management. Specifically, the slow and context‐dependent nature of SOC responses, climate variability, trade‐offs between C sequestration and agronomic benefits, and socio‐economic barriers to implementing SOC‐enhancing practices pose major challenges in adopting management strategies that increase SOC. Addressing these challenges will require long‐term field monitoring, optimization of C and nutrient inputs and soil disturbance, climate‐adaptive management, and supportive economic and policy frameworks. Overall, SOC management should move beyond increasing C stocks alone toward context‐specific strategies that enhance SOC‐associated soil functions and support crop productivity and agroecosystem resilience.
