Effect of different biochar and fertilizer types on N2O and NO emissions

Several hypotheses for our observations exist, which were assessed against current literature and discussed thoroughly. In our study, the decreased N2O and NO emissions are expected to be mediated by multiple interacting phenomena such as stimulated NH3 volatilization, microbial N immobilization, non-electrostatic sorption of NH4+ and NO3−, and biochar pH effects.
