Md Rezaul Karim; Sean C. Thomas Environmental Science & Technology 2026. doi:10.1021/acs.est.6c01265

Other claims from this paper (6)

Observation Control tree foliage emitted CH 4 at 0.03–0.13 nmol·m –2 ·s –1.
Observation Control tree foliage emitted N 2 O at 0.06–0.12 pmol·m –2 ·s –1.
Intervention effect Biochar shifted foliar methane exchange from weak emission to net uptake.
Association Soil and foliar gas fluxes were strongly coupled.
Intervention effect City scaling suggested biochar could convert canopy methane emissions to net uptake.
Intervention effect City scaling suggested biochar could halve nitrous oxide emissions.
