Biochar’s electron shuttle potential mitigates N2O emissions by counteracting the stimulatory effect of rice root iron plaque

Iron (Fe) plaque on rice roots can enhance nitrous oxide (N2O) emissions from paddy soil, primarily through Fe(II) oxidation-coupled denitrification. In this study, our hypothesis is that biochar will reduce N2O emissions via an electron shuttle and complete denitrification. To test this hypothesis,...
