Abstract:
Biochar application has been suggested as a strategy to decrease nitrous oxide emissions from agricultural soils while increasing soil C stocks, especially in tropical regions. Climate change, specifically increasing temperatures, will affect soil environmental conditions and thereby directly influence soil N 2 O fluxes. Here, we show that Miscanthus giganteus biochar applied at high rates suppresses the typical warming-induced stimulation of N 2 O emissions. Specifically, in experiments with high biochar addition (25 Mg ha −1 ), N 2 O emissions under 40°C were equal to or even lower compared to those observed at 20°C. In this sense, the mitigation potential of biochar for N 2 O emissions might increase under the auspices of climate change.
