日本語
有機キャベツ栽培において、微生物を接種した酸性バイオ炭ペレット（ABPM）を土壌に施用したところ、土壌炭素貯留が29.1%増加し、温室効果ガス排出が低減された。また、根こぶ病の発生率が46.2%減少し、収量が8.6%向上した。一季の試験であり、複数年にわたる検証が必要。
English
In organic cabbage cultivation, soil incorporation of microbially engineered biochar pellets (ABPM) increased soil carbon sequestration by 29.1% and reduced cumulative greenhouse gas emissions, leading to positive net ecosystem carbon balance. ABPM27 also reduced clubroot disease incidence by 46.2% and increased marketable yield by 8.6%. However, results are from a single-season experiment and need multi-year validation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもバイオ炭による炭素貯留（J-クレジット）や有機農業が注目されている。本論文は、バイオ炭が炭素貯留と病害抑制の両方に効果があることを示す実証データを提供し、日本の有機栽培やカーボンファーミング政策に示唆を与える。
In the global GX context
This paper presents field evidence of biochar pellets' dual role in carbon sequestration and disease suppression, relevant to global climate-smart agriculture and carbon farming initiatives. The positive NECB values suggest potential for scaling biochar application in organic systems, though replication across regions and seasons is needed.
👥 読者別の含意
🔬研究者:Soil carbon and sustainable agriculture researchers can use these results for meta-analyses or to design multi-season trials.
🏢実務担当者:Organic farmers and biochar producers may consider ABPM for carbon benefits and disease control, but should await further validation.
🏛政策担当者:Policymakers in agricultural carbon programs (e.g., J-credit, 4 per 1000) may note biochar's potential for dual benefits.
📄 Abstract（原文）
Organic vegetable cultivation requires soil management strategies that improve carbon balance and suppress soilborne diseases. This study evaluated the efficacy of acidified microbial biochar pellets (ABPM) in enhancing net ecosystem carbon balance (NECB) and suppressing clubroot disease (Plasmodiophora brassicae) during organic Chinese cabbage (Brassica rapa ssp. pekinensis) cultivation. In a field-scale evaluation, three treatments were compared: guano fertilizer (control), ABPM 27 (inoculated with Pseudomonas fluorescens 22BCO027), and ABPM 86 (inoculated with Bacillus megaterium 22BCO086). Soil incorporation of ABPM 27 and ABPM 86 significantly increased soil carbon sequestration by 29.1% and 22.4%, respectively, while simultaneously reducing cumulative greenhouse gas emissions under the experimental conditions. This resulted in positive NECB values of 2.63 and 2.94 t CO2-eq ha−1, suggesting enhanced carbon retention potential within the studied cultivation system. Beyond its impact on carbon dynamics, ABPM 27 increased marketable yield by 8.6% (77.4 t ha−1) and reduced clubroot incidence by 46.2%. Rhizosphere microbial analysis revealed that ABPM 27 promoted late-season microbial diversity and the persistence of beneficial Bacillus spp. and Pseudomonas spp. populations. These findings suggest the potential multifunctional role of microbially engineered biochar pellets in improving crop production, carbon retention, and pathogen suppression under organic cultivation conditions. However, these findings are based on a single-season field experiment and NECB-based carbon balance estimates, and therefore require validation across multiple growing seasons and cultivation environments.
