 note = {Eighty-nine percent of organic fertilized or certified vegetables from the markets or provided from the prefectural or national agricultural stations showed values of δ^15N higher than +4‰, while 37% of the vegetables which were not organic fertilized or certified vegetables showed values of δ^15N higher than +4‰ (29 kinds of vegetable, 235 samples). These results suggested the possibility to apply δ^15N values as an indicator for certification of vegetables grown only with organic fertilizer.},
