Replication data for: N2O and CH4 emission from soil amended with steam-activated biochar uri icon

abstract

  • Steam-activation increased CH4 emission of stover biochar but decreased it for wood biochar by 14%–70%. Biochar generally increased CH4 emission but reduced N2O emission by 10%–41%. Emission of N2O 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 CH4 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 CO2 equivalent was observed among biochar grades
