METHOD FOR DISCRIMINATING ORGANIC AGRICULTURAL PRODUCTS FROMCONVENTIONAL AGRICULTURAL PRODUCTS BY USING NITROGEN ISOTOPE INDEX |
摘要 |
The present invention provides a method for discriminating an organic farmla nd from a conventional farmland, comprising; (a) measuring an amount of nitroge n isotope in a soil sample of a farmland; (b) calculating a nitrogen isotope index according to the formula (I) using the resultant nitrogen isotope valu e and (c) determining whether the farmland belongs to an organic farmland or a conventional farmland. According to the present invention, it is possible to objectively discriminate an organic farmland from a conventional farmland or discriminate an organic crop from a conventional crop. |
