In this paper, firstly we described calculation methods of N and P flows, then made a mini-review of our past works done as the application of this database. National average and prefectural median of N and P balance on farmlands was reduced in accordance to reduction of input of chemical fertilizer without reducing crop N and P productions. Utilization of livestock excreta N and P was reduced in 2005 in spite of increase of non-utilized part. Residual N and P on agricultural production was decreased, however, prefectural maxima increased by intensification of livestock excreta production and minima decreased by lowering chemical fertilizers input. Nitrogen and P surplus was decreased in 2005 comparing with 1985 except vegetables. Vegetables indicated higher surplus in some prefectures than tea that receives the highest N and P on national average. On the other hand, forages indicated N deficiency in some prefectures. Therefore, reduced input of chemical fertilizers for vegetables would be important to reduce prefectural and national N and P surplus. This database can be utile for basic unit to indicate N and P surplus and deficiency with in prefectures minutely. We can also calculate potential of outflow of N and P from farmland to river or ground water, nitrous oxide emission associated with N flow.","subitem_description_type":"Abstract"},{"subitem_description":"本稿ではアンケートデータや統計データから農業生産に関る窒素・リン酸収支を求めるための方法を確立し、算出結果を表計算ソフト上に収録しデータベース化を行った。ここには、都道府県ごとに、耕種として水田・畑・野菜・果樹・茶・飼料作物に関して生産のために投入される窒素･リン酸と作物生産量、収支が収録されている。また畜種に関しては家畜ふん尿窒素･リン酸の排泄量、堆肥としての利用量、廃棄量、堆肥化過程の窒素消失量を収録している。都道府県を単位として、作目・農業生産全体での窒素･リン酸収支の傾向を見ると、化学肥料の投入の減少に伴って農地表面での窒素･リン酸収支は減少したが、農業生産量は変化が無かった。家畜ふん尿の利用は減少しつつあり、廃棄は増えていた。作目別に見ると野菜での施肥が増加しており、地域によってはこれまで最も化学肥料の施用が多かった茶を超える場合も見られた。野菜への施肥を削減することが重要になるであろう。本データベースの値を原単位として、県内での窒素･リン酸過剰 (欠乏) を表示することも可能であり、分布には窒素とリン酸で違いがあった。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002985","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業環境技術研究所"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00002985","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0911-9450","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"三島, 慎一郎"},{"creatorName":"ミシマ, シンイチロウ","creatorNameLang":"ja-Kana"},{"creatorName":"MISHIMA, Shimichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1789","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20354110","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20354110"},{"nameIdentifier":"read0125678","nameIdentifierScheme":"researchmap","nameIdentifierURI":"http://researchmap.jp/read0125678"}]},{"creatorNames":[{"creatorName":"神山, 和則"},{"creatorName":"コウヤマ, カズノリ","creatorNameLang":"ja-Kana"},{"creatorName":"KOHYAMA, Kazunori","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1145","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50414503","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50414503"},{"nameIdentifier":"Solk","nameIdentifierScheme":"researchmap","nameIdentifierURI":"http://researchmap.jp/Solk"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-10-09"}],"displaytype":"detail","filename":"niaes_report_No27p117-139p.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"niaes_report_No27p117-139p.pdf","url":"https://repository.naro.go.jp/record/3110/files/niaes_report_No27p117-139p.pdf"},"version_id":"bb1dfe48-29aa-4402-98c6-8e2b5dd78f07"}]},"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":"近年の日本・都道府県における窒素・リン酸フローと余剰窒素・リン酸の傾向に関する算出方法とデータベースおよび運用例","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"近年の日本・都道府県における窒素・リン酸フローと余剰窒素・リン酸の傾向に関する算出方法とデータベースおよび運用例"},{"subitem_title":"The database and the methodologies to estimate recent trend of nitrogen (N) and phosphate (P) flows and residual N and P in Japanese national prefectural scales and examples their application","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["407"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-12-20"},"publish_date":"2019-12-20","publish_status":"0","recid":"3110","relation_version_is_last":true,"title":["近年の日本・都道府県における窒素・リン酸フローと余剰窒素・リン酸の傾向に関する算出方法とデータベースおよび運用例"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T15:40:22.277715+00:00"}
