The present invention provides a method for discriminating an organic farmland from a conventional farmland, comprising; (a) measuring an amount of nitrogen isotope in a soil sample of a farmland; (b) calculating a nitrogen isotope index according to the formula (I) using the resultant nitrogen isotope value 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.
La présente invention concerne un procédé qui permet de distinguer des terres agricoles organiques de terres agricoles traditionnelles, selon lequel : (a) on mesure une quantité d'isotopes d'azote dans un échantillon de terre en provenance de terres agricoles ; (b) on calcule un indice d'isotopes d'azote selon la formule (1) en utilisant la valeur d'isotopes d'azote obtenue ; et (c) on détermine si les terres ayant fourni l'échantillon de terre appartiennent à des terres agricoles organiques ou à des terres agricoles traditionnelles. L'invention permet de distinguer de façon objective des terres agricoles organiques de terres agricoles traditionnelles ou de distinguer une récolte organique d'une récolte traditionnelle.
