Our previously developed air plasma device, selectively generating dinitrogen pentoxide (N₂O₅) enables agricultural applications of plasma generated N₂O₅ We focused on experimental evaluation of artificial nitrogen fixation efficacy of plasma generated N₂O_5, a precursor of nitric acid, throughout experiments comparing the growth of Lotus japonicus, a model legume, supplying plasma generated N₂O₅ with symbiotic nitrogen fixation by inoculating rhizobia and mineral nitrogen fertilizer (KNO₃).
