The experiment was conducted in a single paddy field under same conditions except for soils. Rice plants were grown in frames, which the seven different soils (four alluvial paddy soils and three andic paddy soils) were repacked. Not only a small percolation condition (i.e. original subsoil (OS) plot) but also an increased percolation condition was treated by the replacement of subsoil with sand (i.e. sandy subsoil (SS) plot). Percolation rate was lower in clayey smectitic (1-2mm day^<-1>) than in sandy and andic (5-9mm day^<-1>) soils in the SS plots. In the OS plots, percentage of exchangeable ammonium-N in total soil ammonium N was 89-96% in all soils at 11 days after transplanting (DAT), and was higher in soils with the large ammonium adsorption of PL. Soil ammonium-N at 40 DAT (i.e. at active-tillering stage), N uptake at harvest and brown rice yield were explained by the available N of PL in the OS plots. It is considered that the difference of ammonium adsorption of PL did not strongly affect them, because of its small variation and the small percolation. In the SS plots, the soil ammonium-N at 40 DAT was explained by the ammonium adsorption and the available N of PL. It is considered that soil ammonium-N was much protected from leaching and denitrification in soils with the large ammonium adsorption of PL. However, the total N uptake and the brown rice yield were effectively explained by the available N of PL, and the ammonium adsorption of PL was not selected as an important parameter. It is considered that the ammonium adsorption of PL did not strongly affect the N uptake after maximum tillering stage. The ammonium adsorption of PL did not significantly related to recovery rate of fertilizer N both in the OS and SS plots because of the small variation in the ammonium adsorption of PL among soils.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類","subitem_description_type":"Other"}]},"item_4_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Original Paper","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"1216814 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Field Science Center, Graduate School of Agricultural Science, Tohoku University"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2433-6122","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12005506","subitem_source_identifier_type":"NCID"}]},"item_4_text_72":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Field Science Center, Graduate School of Agricultural Science, Tohoku University / Field Science Center, Graduate School of Agricultural Science, Tohoku University / Field Science Center, Graduate School of Agricultural Science, Tohoku University:(Present office)Toyohashi University of Technology"}]},"item_4_version_type_16":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SANO, Oki"}],"nameIdentifiers":[{"nameIdentifier":"152370","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ITO, Toyoaki"}],"nameIdentifiers":[{"nameIdentifier":"152371","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SAIGUSA, Masahiko"}],"nameIdentifiers":[{"nameIdentifier":"152372","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":"2017-02-22"}],"displaytype":"detail","filename":"KJ00005127909.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005127909.pdf","url":"https://tohoku.repo.nii.ac.jp/record/64147/files/KJ00005127909.pdf"},"version_id":"4b5a5b80-a7cd-4f30-bb09-111e6ebcdd9f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"paddy soil","subitem_subject_scheme":"Other"},{"subitem_subject":"available nitrogen","subitem_subject_scheme":"Other"},{"subitem_subject":"ammonium adsorption","subitem_subject_scheme":"Other"},{"subitem_subject":"rice","subitem_subject_scheme":"Other"},{"subitem_subject":"recovery rate","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Effects of available nitrogen and ammonium adsorption of plow layer on nitrogen uptake and yield of paddy rice (Oryza sativa L.)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of available nitrogen and ammonium adsorption of plow layer on nitrogen uptake and yield of paddy rice (Oryza sativa L.)"}]},"item_type_id":"4","owner":"3","path":["198"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"64147","relation_version_is_last":true,"title":["Effects of available nitrogen and ammonium adsorption of plow layer on nitrogen uptake and yield of paddy rice (Oryza sativa L.)"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T23:43:00.687020+00:00"}
