摘要
A new gas permeability model was developed for vegetated soil with biochar.Grassed soil with decay roots  had the largest gas permeability at any water content.Biochar–grass interaction leads to the lowest gas permeability.Gas emission rate decreased with deeper root depth in biochar-grass case.Biochar can reduce gas emission rate even under drought condition.
