📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では農地への炭素貯留が「みどりの食料システム戦略」で推進されており、バイオ炭は地域資源循環型農業に適合する。本レビューは原料選定や施用率の指標を提供し、国内での実用化検討に資する。

In the global GX context

Globally, biochar is recognized as a negative emissions technology under IPCC pathways. This review provides a practical synthesis for scaling biochar in agriculture, relevant to carbon farming initiatives, voluntary carbon markets, and national greenhouse gas inventories.

08 Biochar Production and Application in Agriculture: A Review on Soil Fertility, Crop Productivity and Climate Change Mitigation Sumit1, V. K. Singh2, Sumit Gaur2, Sambita Bhattacharyya2 1Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh -284003, India 2Govind Ballabh Pant University of Agriculture & Technology Pantnagar, Uttarakhand-263145, India Corresponding author email: [email protected] DOI : 10.5281/zenodo.20531091 Abstract Biochar, a stable carbon-rich product derived from pyrolysis of organic biomass, offers a sustainable approach to improving soil health and crop productivity. Locally available materials, such as rice husk, wheat straw, maize stover and animal manures serve as cost-effective feedstocks. Production parameters, such as pyrolysis temperature, heating rate, and residence time, significantly influence biochar’s physical and chemical properties, which is improve nutrient retention, water-holding capacity, microbial activity and soil fertility. Application rates typically range from 5-20 t/ha, alone or in combination with fertilizers, depending on soil type and crop needs. Field adoption has demonstrated increased crop yields, reduced fertilizer requirements, and enhanced soil resilience, while also contributing to carbon sequestration. Suitable feedstocks, production methods, application method and optimum use of biochar can be enhanced efficiency of biochar.
