Short summary

We investigated the potential for chemical reduction of nitrite into nitrous oxide (N₂O) in soils from tropical peat. Among treatments, irradiation resulted in the lowest biological interference and least change of native soil chemistry (iron and organic matter). Nitrite depletion was as high in live or irradiated soils, and N₂O production was significant in all tests. Thus, nonbiological production of N₂O may be widely underestimated in wetlands and tropical peatlands.
