The objective of the present study was to elucidate any differences in N_2O production and flux in the soil profile between these two soil types. In the Gray Lowland soil, the N_2O concentration above 0.4 m increased with an increase in soil depth. In the Andosol, there were no distinctive N_2O concentration gradients in the topsoil when the N_2O flux did not increase. However, the N_2O concentration at a depth of 0.1 m significantly increased and this concentration was higher than the concentration below 0.2 m when the N_2O flux greatly increased. Thus, the N_2O concentration profiles were different between these two soils. The contribution ratios of the N_2O produced in the top soil (0-0.3 m depth) to the total N_2O emitted from the soil to the atmosphere in the Gray Lowland soil and the Andosol were 0.86 and 1.00, respectively, indicating that the N_2O emitted from the soil to the atmosphere was mainly produced in the top soil. However, the contribution ratio of the subsoil to the N_2O emitted from the Gray Lowland soil was higher than that of the Andosol. There was a significant positive correlation between the N_2O flux through to a 0.3 m depth and the flux from the soil to the atmosphere in the Gray Lowland soil only. These results suggest that N_2O production in the subsoil of the Gray Lowland soil could have been activated by NO_3^− leaching through macropores and cracks, and subsequently the N_2O produced in the subsoil could have been rapidly emitted to the atmosphere through the macropores and cracks.","subitem_description_type":"Abstract"}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley-Blackwell"}]},"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.1747-0765.2009.00439.x","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2010 Japanese Society of Soil Science and Plant Nutrition"}]},"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":"KUSA, Kanako"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"SAWAMOTO, Takuji","creatorNameLang":"en"},{"creatorName":"澤本, 卓治","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"HU, Ronggui"}],"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-2011-15_Sawamoto.pdf","filesize":[{"value":"950.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S-2011-15_Sawamoto.pdf","url":"https://rakuno.repo.nii.ac.jp/record/354/files/S-2011-15_Sawamoto.pdf"},"version_id":"7da5744d-1c47-4edc-b16e-9d6753a2fece"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Andosol","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon dioxide","subitem_subject_scheme":"Other"},{"subitem_subject":"gas concentration in soil profile","subitem_subject_scheme":"Other"},{"subitem_subject":"Gray Lowland soil","subitem_subject_scheme":"Other"},{"subitem_subject":"nitrous oxide","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":"Comparison of N_2O and CO_2 concentrations and fluxes in the soil profile between a Gray Lowland soil and an Andosol","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Comparison of N_2O and CO_2 concentrations and fluxes in the soil profile between a Gray Lowland soil and an Andosol"}]},"item_type_id":"2","owner":"3","path":["14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-01"},"publish_date":"2012-10-01","publish_status":"0","recid":"354","relation_version_is_last":true,"title":["Comparison of N_2O and CO_2 concentrations and fluxes in the soil profile between a Gray Lowland soil and an Andosol"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-30T01:59:16.035811+00:00"}
