Concentrations of total I and potentially plant available I (i.e. water soluble and organically bound iodine) were measured in 141 agricultural soil samples. For total I measurements, pressed powder pellets were prepared from soil samples and concentrations of I were measured by energy dispersive X-ray fluorescence. Potentially plant available I contents were measured by inductively coupled plasma mass spectrometry after soil samples had been extracted with tetramethyl ammonium hydroxide and their soluble and organically bound I concentrations had been measured (TMAH-extractable I). The results showed a high correlation between the total and TMAH-extractable I concentrations. The geometric means of total and TMAH-extractable I in the paddy field samples were 1.9 and 1.1 mg kg-1-dry, respectively, while those in the upland field soil samples were 5.7 and 4.2 mg kg-1-dry, respectively. For the agricultural soils having less than 5 mg kg-1 total I, it was estimated that the average concentrations of plant unavailable I in paddy fields and upland fields were 0.7+/-0.2 mg kg-1-dry and 0.7+/-0.4 mg kg-1-dry, respectively. The different total I concentrations for fields of the two agricultural uses could be explained by the differences in their redox conditions; I is mobile under reducing conditions so that it was removed from the paddy fields by leaching from the plowed layer or by I volatilization from the soil.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0361-5995","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tagami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"457061","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchida, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"457062","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takeda, Akira"}],"nameIdentifiers":[{"nameIdentifier":"457063","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamasaki, Shin-ichi"}],"nameIdentifiers":[{"nameIdentifier":"457064","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"457065","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田上 恵子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"457066","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内田 滋夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"457067","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山崎 慎一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"457068","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Estimation of plant unavailable iodine concentrations in agricultural fields","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of plant unavailable iodine concentrations in agricultural fields"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-11"},"publish_date":"2010-11-11","publish_status":"0","recid":"45942","relation_version_is_last":true,"title":["Estimation of plant unavailable iodine concentrations in agricultural fields"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:57:45.895384+00:00"}
