本論文は、農生態系における耕起の戦略的役割を再評価し、無農薬システムでの雑草・病害虫管理と被覆作物管理における耕起の重要性を指摘。土壌有機炭素（SOC）の動態と温室効果ガス排出に関する知見を統合し、耕起がSOCの総量よりも分布に影響すること、不耕起によるSOC増加の可能性をN₂O排出が相殺しうることを示す。SOCの蓄積は炭素投入量と多様性に主に依存するため、耕起を炭素投入、生態機能、温室効果ガス収支の枠組みで評価する統合的アプローチを提唱する。
English
This paper re-evaluates tillage as a strategic practice in agroecological systems, highlighting its role in weed and pest control and cover crop management in pesticide-free systems. Synthesizing recent findings, it shows that tillage affects SOC distribution more than stock, and that N₂O emissions can offset potential SOC gains under no-till. SOC stocks are mainly controlled by carbon input quantity and diversity. The authors advocate an integrated, systems-based approach to assess tillage within carbon inputs, ecological functions, and greenhouse gas balances.

📄 Abstract（原文）
Abstract Agroecological transitions face a dual imperative: reducing pesticide reliance and minimising soil disturbance for climate mitigation. However, the blanket promotion of no-till practices may hinder ecological innovation by overlooking real-world trade-offs. This article re-examines tillage as a strategic practice in pesticide-free systems, especially for weed and pest control and cover crop management. We synthesise recent findings on soil organic carbon (SOC) dynamics and greenhouse gas emissions, showing that tillage impacts SOC distribution in the soil profile more than stock, and that nitrous oxide (N₂O) emissions can offset potential SOC gains under no-till. SOC stocks are mostly controlled by the quantity and diversity of carbon inputs. We argue for an integrated, systems-based agroecological approach that assesses tillage within the broader framework of carbon inputs, ecological functions, and greenhouse gas balances. Reframing tillage is essential to design resilient, low-input, climate-positive farming systems.
