The changes of soil management were as follows; (1) slight decrease in nitrogen and phosphate fertilizer application rates, (2) decrease to half in the application of soil amendments, like calcium silicate, (3) decrease in compost application and increase in rice straw application, (4) increase in pipe drainage. In spite of these changes, negligible change of carbon content in the plow-layer of alluvial paddy soils had been observed for past twenty-five years. However, without rice straw application and paddy-upland rotations, the soil carbon content had been decreased. Carbon content of alluvial paddy soils classified into Gley Lowland soil (Fluvisol or Gleysol) at the depth of 0-30 cm was calculated about 49-103 g/kg and gross carbon sequestration was calculated 7.68 Mt in the paddy field soils in Niigata prefecture.", "subitem_description_type": "Abstract"}]}, "item_8_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "19th World Congress of Soil Science, Soil Solutions for a Changing World"}]}, "item_8_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Honma, Toshimitsu"}], "nameIdentifiers": [{"nameIdentifier": "168693", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohba, Hirotomo"}], "nameIdentifiers": [{"nameIdentifier": "168694", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohyama, Takuji"}], "nameIdentifiers": [{"nameIdentifier": "52", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "19_84-87.pdf", "filesize": [{"value": "392.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 392100.0, "url": {"label": "19_84-87.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/30877/files/19_84-87.pdf"}, "version_id": "4a597cd6-7468-4a24-9724-ca561cdd6d5c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Carbon sequestration", "subitem_subject_scheme": "Other"}, {"subitem_subject": "soil survey", "subitem_subject_scheme": "Other"}, {"subitem_subject": "alluvial paddy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "soil management", "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": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Effects of soil management on changes of soil carbon content in alluvial paddy soil in Niigata", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Effects of soil management on changes of soil carbon content in alluvial paddy soil in Niigata"}, {"subitem_title": "Effects of soil management on changes of soil carbon content in alluvial paddy soil in Niigata", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "1", "path": ["457", "1814"], "permalink_uri": "http://hdl.handle.net/10191/23743", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-10-09"}, "publish_date": "2013-10-09", "publish_status": "0", "recid": "30877", "relation": {}, "relation_version_is_last": true, "title": ["Effects of soil management on changes of soil carbon content in alluvial paddy soil in Niigata"], "weko_shared_id": null}
