Steam‐activation increased CH 4 emission of stover biochar but decreased it for wood biochar by 14% – 70%. Biochar generally increased CH 4 emission but reduced N 2 O emission by 10%–41%. Emission of N 2 O was 17% lower for maize‐stover biochar compared to Eucalyptus ‐wood biochar, and 3% lower for 350°C compared to 550°C pyrolysis temperature. Emission of CH 4 was 21% higher for activated stover biochar compared to Eucalyptus ‐wood biochar and 10% lower for 350°C compared to 550°C pyrolysis temperature. No difference in net CO 2 equivalent was observed among biochar grades.
