SOM decay processes from organic carbon to biomass carbon, humus carbon, and carbon dioxide were described using first-order kinetics. When oxygen was available in an aerobic condition, O2 was used to produce CO2 as an electron accepter. When O2 availability is low, other electron acceptors such as NO3-, Mn4+, Fe3+, SO42-, were used depending on the redox potential. Decomposition of Org-N was related to the carbon cycle using the C/N ratio. Furthermore, cation and anion exchange reactions were included with the permanent negative charges and the pH dependent variable charges. The carbon and nitrogen cycling model described with PHREEQC was linked with HYDRUS-1D using the HP1 code. Various nitrogen and carbon transport scenarios were demonstrated for the application of organic matter to a saturated paddy soil.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2020年度～2022年度科学研究費補助金(基盤研究(B))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"20H03098","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"取出, 伸夫","creatorNameLang":"ja"},{"creatorName":"Toride, Nobuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"渡辺, 晋生","creatorNameLang":"ja"},{"creatorName":"Watanabe, Kunio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"坂井, 勝","creatorNameLang":"ja"},{"creatorName":"Sakai, Masaru","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"橋本, 洋平","creatorNameLang":"ja"},{"creatorName":"Hashimoto, Yohei","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"徳本, 家康","creatorNameLang":"ja"},{"creatorName":"Tokumoto, Ieyasu","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-28"}],"filename":"2024RP0098.pdf","filesize":[{"value":"471 KB"}],"format":"application/pdf","url":{"label":"2024RP0098.pdf","url":"https://mie-u.repo.nii.ac.jp/record/2001008/files/2024RP0098.pdf"},"version_id":"353dc32c-c651-4748-bb93-f60bc1f36bf9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"水田","subitem_subject_scheme":"Other"},{"subitem_subject":"畑","subitem_subject_scheme":"Other"},{"subitem_subject":"有機物分解","subitem_subject_scheme":"Other"},{"subitem_subject":"窒素循環","subitem_subject_scheme":"Other"},{"subitem_subject":"炭素循環","subitem_subject_scheme":"Other"},{"subitem_subject":"反応移動モデル","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"水田・畑の窒素炭素循環と反応移動の体系化－根群域から団粒生態系まで－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水田・畑の窒素炭素循環と反応移動の体系化－根群域から団粒生態系まで－","subitem_title_language":"ja"},{"subitem_title":"Reactive transport modeling with carbon and nitrogen cycling for micro-aggregate up to root-zone scales in paddy and upland fields","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1728958246114"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-28"},"publish_date":"2024-10-28","publish_status":"0","recid":"2001008","relation_version_is_last":true,"title":["水田・畑の窒素炭素循環と反応移動の体系化－根群域から団粒生態系まで－"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-10-28T00:35:05.855110+00:00"}
