Annual changes in soil carbon contents were assessed by measuring soil organic matter (SOM) via loss on ignition from 2014 to 2020. Our results suggest that (i) in soils with low carbon content, land use change from maize field to meadow increases the soil carbon content, (ii) in soils with medium or low carbon content, preserving meadow land use increases the soil carbon content, and (iii) land use change from meadow to maize field decreases the soil carbon content over time. We estimated annual soil carbon sequestration, in the form of SOM, was 21 t-C year-1 in the 35 fields. Annual carbon dioxide emission (diesel fuel combustion in tractors) was estimated at 19. 6 t-C year-1. Our findings indicate that increasing SOM by land use planning contributes to both improving soil quality for forage crop production and mitigating global warming by offsetting farm equipment carbon dioxide emissions through soil carbon sequestration.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"酪農学園大学","subitem_publisher_language":"ja"}]},"item_7_relation_12":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"AN00247860","subitem_relation_type_select":"NCID"}}]},"item_7_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2187-0500","subitem_source_identifier_type":"EISSN"}]},"item_7_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"石田,清二","creatorNameLang":"ja"},{"creatorName":"イシダ,セイジ","creatorNameLang":"ja-Kana"},{"creatorName":"ISHIDA,Seiji","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{},{}]}],"creatorNames":[{"creatorName":"澤本,卓治","creatorNameLang":"ja"},{"creatorName":"サワモト,タクジ","creatorNameLang":"ja-Kana"},{"creatorName":"SAWAMOTO,Takuji","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2024-03-12"}],"displaytype":"detail","filename":"S-48-2-159-174.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://rakuno.repo.nii.ac.jp/record/2000098/files/S-48-2-159-174.pdf"},"version_id":"3329935b-34fd-4cd6-aa35-a5152054c875"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"酪農学園文京台地区の飼料作物生産圃場における土壌炭素隔離","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"酪農学園文京台地区の飼料作物生産圃場における土壌炭素隔離","subitem_title_language":"ja"},{"subitem_title":"ラクノウ ガクエン ブンキョウダイ チク ノ シリョウ サクモツ セイサン ホジョウ ニオケル ドジョウ タンソ カクリ","subitem_title_language":"ja-Kana"},{"subitem_title":"Soil carbon sequestration in forage crop fields in the Bunkyodai area of Rakuno Gakuen, Hokkaido, Japan","subitem_title_language":"en"}]},"item_type_id":"7","owner":"10","path":["1710232436856"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-12"},"publish_date":"2024-03-12","publish_status":"0","recid":"2000098","relation_version_is_last":true,"title":["酪農学園文京台地区の飼料作物生産圃場における土壌炭素隔離"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-03-13T00:27:09.096867+00:00"}
