Rhizosphere carbon and nitrogen partitioning mediates inhibitor effects on yield and greenhouse gas emissions across irrigation regimes in rice paddies

日本語

水田の灌漑条件の違いが、根圏の炭素・窒素分配を介して、硝化・ウレアーゼ阻害剤の収量と温室効果ガス排出への効果に影響することを示した研究。阻害剤の効果は灌漑管理に依存し、GHG削減と収量維持の両立には条件に応じた最適化が必要。

English

This study shows that irrigation regimes in rice paddies mediate the effects of nitrification and urease inhibitors on yield and greenhouse gas emissions through rhizosphere carbon and nitrogen partitioning. The effectiveness of inhibitors depends on water management, highlighting the need for condition-specific optimization to balance GHG reduction and yield.

日本のGX文脈において

日本の水田農業はGHG排出削減が課題であり、本研究成果は国内の農業分野における排出削減策の最適化に示唆を与える。また、農林水産省の「みどりの食料システム戦略」とも関連し、持続可能な農業実践への応用が期待される。

In the global GX context

This research contributes to global efforts to reduce agricultural greenhouse gas emissions, particularly methane and nitrous oxide from rice paddies. It provides insights for optimizing inhibitor use under different irrigation practices, relevant to climate-smart agriculture and national GHG inventories.
