ブラウンマニューリング（BM）は、主作物とともに栽培した被覆作物を開花期に選択性除草剤で枯殺する不耕起型の緑肥手法である。枯死したバイオマスがその場で分解し、窒素35〜40kg/haやリン・カリを供給しつつ、土壌有機炭素・微生物量・保水性を改善する。雑草を40〜94%抑制し、水稲・トウモロコシ・サトウキビで収量を13〜38%向上、メタン排出を28〜61%削減する。ただし多くは短期・地点限定的で、長期多地点試験が今後の課題である。
English
Brown manuring (BM) is a zero-tillage green-manuring variant where a cover crop is chemically desiccated at flowering, leaving biomass to decompose in situ. It supplies up to 35-40 kg N/ha, raises soil organic carbon and water-holding capacity, suppresses weeds by 40-94%, boosts rice/maize/sugarcane yields 13-38%, and cuts methane emissions 28-61%. Evidence remains short-term and site-specific, so long-term multi-location trials are needed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では水田・畑作の脱炭素と化学肥料依存低減が課題であり、BMは農地由来GHG削減策として参考になる。ただしSSBJ・有報・TCFD開示との直接接続は薄く、Scope 3や農業セクターの気候目標設定に資する周辺知見として位置づけられる。
In the global GX context
Agriculture is a growing frontier for climate disclosure, with Scope 3 land-use emissions and soil-carbon accounting entering ISSB/CSRD discussions. This review offers mitigation evidence (methane cuts, SOC gains) relevant to agri-food transition finance and nature-related reporting, though it does not itself engage disclosure frameworks.

📄 Abstract（原文）
Global agriculture faces mounting pressure to sustain crop productivity while reducing dependence on synthetic inputs and minimising environmental harm. Brown manuring (BM) is a zero-tillage variant of green manuring in which a cover crop, grown alongside the main crop, is chemically desiccated at the flowering stage using a selective herbicide, typically 2,4-dichlorophenoxyacetic acid (2,4-D). Unlike conventional green manuring, BM does not require mechanical incorporation of plant material into the soil, thereby preserving soil structure and reducing labour costs. Upon desiccation, the standing biomass decomposes in situ, releasing N (up to 35–40 kg N ha −1 from leguminous species such as Sesbania spp. and Crotalaria juncea ), P and K, while improving soil organic carbon content, microbial biomass, and water-holding capacity. BM has been shown to suppress weed populations by 40–94% through light interception, allelopathic effects, and surface mulch formation, thereby reducing dependence on chemical herbicides. When integrated with recommended nutrient management, BM has delivered crop yield improvements of 13–38% in rice, maize, and sugarcane systems. Additional benefits include reductions in greenhouse gas emissions particularly methane by 28–61% when leguminous cover crops are used, alongside improved energy-use efficiency under no-tillage conditions. Despite these well-documented advantages, most existing studies are short-term and site-specific, which limits the broader applicability of findings. Long-term, multi-location field trials are therefore needed to comprehensively assess BM’s sustained effects on soil health, disease suppression, and farm-level economic returns across diverse agro-ecosystems. This review consolidates current evidence and highlights priority research areas to support wider adoption of BM within sustainable crop production systems.
