Aims Two field microcosm experiments and ¹⁵N labeling techniques were used to investigate the effects of biochar addition on rice N nutrition and GHG emissions in an Inceptisol and an Ultisol. Methods Biochar N bioavailability and effect of biochar on fertilizer nitrogen-use efficiency (NUE) were st...
