However, as δ<sup>15</sup>N values vary in both organic and conventional rice, it might be difficult to use a particular δ<sup>15</sup>N value as an indicator of organic growth conditions. This review describes an approach that was developed at the Tohoku Agricultural Research Center, National Agriculture and Food<b> </b>Research Organization. The relationship between the δ<sup>15</sup>N values of rice and those of soil under organic or conventional farming conditions has been investigated. Regardless of the farming method, the δ<sup>15</sup>N values of rice reflect those of the soil. The δ<sup>15</sup>N values of organically grown rice tend to be higher than the regression line obtained from the δ<sup>15</sup>N values of rice and soil without the application of an N fertilizer. The δ<sup>15</sup>N values of conventionally grown rice tend to be lower than the regression line. Thus, the relationship between the δ<sup>15</sup>N values of rice and soil without an applied N source could be used to differentiate between organic and conventional rice. However, the existence of regional variation in the relationship between the δ<sup>15</sup>N values of rice and those of unamended soil can confound the use of this discriminant method. Such variation may occur due to the differences in δ<sup>15</sup>N of natural N inputs, and also through ammonia nitrification and subsequent denitrification. Temporal variation can also occur, though the reason for such variation is unknown. When the relationship between the δ<sup>15</sup>N values of rice and those of unamended soil is employed to distinguish between organic and conventional rice, regional and temporal variations in that relationship should be taken into account.</p>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420564276160608768","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"20355324"},{"@type":"NRID","@value":"1000020355324"},{"@type":"NRID","@value":"9000301739717"},{"@type":"NRID","@value":"9000241152249"},{"@type":"NRID","@value":"9000391399780"},{"@type":"NRID","@value":"9000375907396"},{"@type":"NRID","@value":"9000411502368"},{"@type":"NRID","@value":"9000344839875"},{"@type":"NRID","@value":"9000018856918"},{"@type":"NRID","@value":"9000241152244"},{"@type":"NRID","@value":"9000411090023"},{"@type":"NRID","@value":"9000405383096"},{"@type":"NRID","@value":"9000396110776"},{"@type":"NRID","@value":"9000406324768"},{"@type":"NRID","@value":"9000258471043"},{"@type":"NRID","@value":"9000318571617"},{"@type":"NRID","@value":"9000319547309"},{"@type":"NRID","@value":"9000375907433"},{"@type":"NRID","@value":"9000405470739"},{"@type":"NRID","@value":"9000396170583"},{"@type":"NRID","@value":"9000256910927"},{"@type":"NRID","@value":"9000401558496"},{"@type":"NRID","@value":"9000388467530"},{"@type":"NRID","@value":"9000402102017"},{"@type":"NRID","@value":"9000375906008"},{"@type":"NRID","@value":"9000375906475"},{"@type":"NRID","@value":"9000375893719"},{"@type":"NRID","@value":"9000405336136"},{"@type":"NRID","@value":"9000396108811"},{"@type":"NRID","@value":"9000375907362"},{"@type":"NRID","@value":"9000401555701"},{"@type":"NRID","@value":"9000396129229"},{"@type":"NRID","@value":"9000375905991"},{"@type":"NRID","@value":"9000405444815"},{"@type":"NRID","@value":"9000256910365"},{"@type":"NRID","@value":"9000415404602"},{"@type":"NRID","@value":"9000318570549"},{"@type":"NRID","@value":"9000375906889"},{"@type":"NRID","@value":"9000347085457"},{"@type":"NRID","@value":"9000415179750"},{"@type":"NRID","@value":"9000003023057"},{"@type":"NRID","@value":"9000283738712"},{"@type":"NRID","@value":"9000405397480"},{"@type":"NRID","@value":"9000396110730"},{"@type":"NRID","@value":"9000399224255"},{"@type":"NRID","@value":"9000375906152"},{"@type":"NRID","@value":"9000415199460"},{"@type":"NRID","@value":"9000404519156"},{"@type":"NRID","@value":"9000405323585"},{"@type":"NRID","@value":"9000404468199"},{"@type":"NRID","@value":"9000397660227"},{"@type":"NRID","@value":"9000322679574"},{"@type":"NRID","@value":"9000415219379"},{"@type":"NRID","@value":"9000412099572"},{"@type":"NRID","@value":"9000405487023"},{"@type":"NRID","@value":"9000411022549"},{"@type":"NRID","@value":"9000318570222"},{"@type":"NRID","@value":"9000386450814"},{"@type":"NRID","@value":"9000347085479"},{"@type":"NRID","@value":"9000405319936"},{"@type":"NRID","@value":"9000397841268"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/mango"}],"foaf:name":[{"@language":"en","@value":"NISHIDA
