From 2000 to 2004, N_2O and NO fluxes ranged from -137 to 8,920 µg N m<−2> h<−1> and from -12.1 to 185 µg N m<−2> h<−1>, respectively. Most N_2O/NO ratios calculated on the basis of these N_2O and NO fluxes ranged between 1 and 100, and the log-normal N_2O/NO ratio was positively correlated with the log-normal N_2O fluxes (r^2 = 0.346, P < 0.01). These high N_2O fluxes, therefore, resulted from increased denitrification activity. Annual N_2O emission rates ranged from -1.0 to 81 kg N ha<−1> year<−1> (average = 6.6 kg N ha<−1>). As these emission values varied greatly and included extremely high values, we divided them into two groups: normal values (i.e. values lower than the overall average) and high values (i.e. values higher than average). The normal data were significantly positively correlated with N input (r^2 = 0.61, P < 0.01) and the “higher” data from ungrazed fields were significantly positively correlated with N surplus (r^2 = 0.96, P < 0.05). The calculated probability that a high N_2O flux would occur was weakly and positively correlated with precipitation from May to August. This probability can be used to represent annual variation in N_2O emission rates and to reduce the uncertainty in N_2O estimation.","subitem_description_type":"Abstract"}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Blackwell Publishing"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1111/j.1747-0765.2008.00284.x","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The definitive version is available at www.blackwellsynergy.com"}]},"item_2_rights_16":{"attribute_name":"権利（URI）","attribute_value_mlt":[{"subitem_rights":"http://dx.doi.org/10.1111/j.1747-0765.2008.00284.x | http://dx.doi.org/10.1111/j.1747-0765.2008.00284.x"}]},"item_2_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0038-0768","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KATAYANAGI, Nobuko"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"SAWAMOTO, Takuji","creatorNameLang":"en"},{"creatorName":"澤本, 卓治","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"HAYAKAWA, Atsushi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HATANO, Ryusuke"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-09-14"}],"displaytype":"detail","filename":"S-403_Sawamoto.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S-403_Sawamoto.pdf","url":"https://rakuno.repo.nii.ac.jp/record/394/files/S-403_Sawamoto.pdf"},"version_id":"b36ca81a-1cae-43e1-866c-5023897d4d3d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"nitrous oxide","subitem_subject_scheme":"Other"},{"subitem_subject":"nitric oxide","subitem_subject_scheme":"Other"},{"subitem_subject":"outliers","subitem_subject_scheme":"Other"},{"subitem_subject":"uncertainty","subitem_subject_scheme":"Other"},{"subitem_subject":"watershed","subitem_subject_scheme":"Other"}]},"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":"Nitrous oxide and nitric oxide fluxes from cornfield, grassland, pasture and forest in a watershed in Southern Hokkaido, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nitrous oxide and nitric oxide fluxes from cornfield, grassland, pasture and forest in a watershed in Southern Hokkaido, Japan"}]},"item_type_id":"2","owner":"3","path":["14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-31"},"publish_date":"2011-03-31","publish_status":"0","recid":"394","relation_version_is_last":true,"title":["Nitrous oxide and nitric oxide fluxes from cornfield, grassland, pasture and forest in a watershed in Southern Hokkaido, Japan"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-30T01:59:14.563620+00:00"}
