灌漑オアシス農業では高い生産性が土壌有機炭素（SOC）の長期的保持を保証しない理由を、収量と炭素の分離という観点から検討した統合的レビュー。主要な制約はバイオマス投入量ではなく、塩類集積・マルチ点滴灌漑・残膜蓄積が引き起こす炭素移転のボトルネックにあると整理する。水塩管理・基質微生物管理・土壌マトリックス保護を炭素移転の制約段階に対応づける診断的農法フレームワークを提示する。
English
This integrative review examines why high yields in irrigated oasis croplands do not guarantee durable soil organic carbon retention. It argues the key constraint is not biomass input but carbon-transfer bottlenecks—salinity-driven microbial costs, mulched drip irrigation microsites, and residual plastic film degrading soil structure. The authors propose a diagnostic agronomic framework linking water–salt, substrate–microbe, and soil-matrix regulation to the most constrained transfer stage.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
土壌炭素はScope 3・農業由来排出や炭素クレジットの基礎となり得るが、本稿は制度・開示論には踏み込まず、日本のGX実務への直接的示唆は限定的。ただし農業セクターの気候緩和策を検討する読者には土壌炭素保持の技術的論点を提供する。
In the global GX context
Soil organic carbon underpins agricultural emissions accounting and soil-carbon crediting, which increasingly feed into Scope 3 and nature-related disclosure. The paper offers a technical diagnostic lens rather than a disclosure framework, so its value to global GX scholarship is as agronomic grounding for soil-carbon claims.

📄 Abstract（原文）
ABSTRACT Sustaining food production in arid regions increasingly depends on irrigated oasis agriculture, yet high productivity in these systems does not guarantee durable soil organic carbon (SOC) retention. This integrative narrative review asks why this yield–carbon decoupling occurs in irrigated oasis croplands and how it can be addressed through agronomic regulation. We synthesize evidence showing that the key limitation is not biomass input alone, but a set of carbon‐transfer bottlenecks that restrict belowground carbon entry, microbial conversion, and physical–mineral protection. Salinity increases microbial maintenance costs and reduces microbial‐residue formation. Mulched drip irrigation creates wetting and salt‐accumulation microsites that spatially separate carbon inputs from stabilization sites. Long‐term plastic mulching and residual‐film accumulation further degrade soil structure and weaken the matrix needed to protect transformed carbon. The main contribution of this review is to translate established microbial‐efficiency and carbon‐fraction concepts into a diagnostic agronomic framework for oasis cropping systems. This framework links water–salt regulation, substrate–microbe regulation, and soil‐matrix protection to the stage at which carbon transfer is most constrained. Measurable signals from the root zone, microbial pathway, and soil matrix can help identify potential management priorities. By treating regulation as location‐specific rather than sequential, the framework provides a basis for aligning SOC retention with yield stability, water‐use efficiency, climate mitigation, and resilient food production in water‐limited regions.
