Downward percolation of water during infiltration or redistribution ceases where the infiltrated water migrating through the sand layer encounters the gravel layer, and the water accumulates just above an interface between the soil layers with less percolating into the gravel layer lower. As their roots can easily utilize the water retained within the upper soil layer, agricultural plants grow well even under supply of less irrigation water. In order to study feasibility or applicability of the CB system of soil in an arid or semi-arid area, a site investigation was conducted in the West Bank of the Jordan River, Palestine, during 20 to 25 March, 2015. The CB test plot was constructed in the olive orchard near Ramallah City and, since then, the soil moisture contents in the CB system of soil have been monitored in the field. In this paper, the soil moisture contents measured in the CB test plot are plotted during 79 days after 23 march, 2015, and compared with those measured in the orchard soil without the gravel layer.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"162394","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morii, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"162395","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Fujimaki, Haruyuki"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学農学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00183393","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03858634","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森井, 俊広"}],"nameIdentifiers":[{"nameIdentifier":"162392","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤巻, 晴行"}],"nameIdentifiers":[{"nameIdentifier":"162393","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":"2019-08-20"}],"displaytype":"detail","filename":"68_37-41.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"68_37-41.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/28268/files/68_37-41.pdf"},"version_id":"d67b5a79-599a-4b59-a95f-a3df5b37a40d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"土のキャピラリーバリア","subitem_subject_scheme":"Other"},{"subitem_subject":"ヨルダン川西岸地区","subitem_subject_scheme":"Other"},{"subitem_subject":"適用性調査","subitem_subject_scheme":"Other"},{"subitem_subject":"土壌水分センサー","subitem_subject_scheme":"Other"},{"subitem_subject":"体積含水率","subitem_subject_scheme":"Other"},{"subitem_subject":"Capillary barrier of soil","subitem_subject_scheme":"Other"},{"subitem_subject":"West Bank of the Jordan River","subitem_subject_scheme":"Other"},{"subitem_subject":"Feasibility study","subitem_subject_scheme":"Other"},{"subitem_subject":"Soil moisture sensor","subitem_subject_scheme":"Other"},{"subitem_subject":"Volumetric moisture content","subitem_subject_scheme":"Other"}]},"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":"土のキャピラリーバリア機能を利用した節水かんがいシステムの開発 : パレスチナ自治区ヨルダン川西岸地区における適用可能性調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"土のキャピラリーバリア機能を利用した節水かんがいシステムの開発 : パレスチナ自治区ヨルダン川西岸地区における適用可能性調査"},{"subitem_title":"土のキャピラリーバリア機能を利用した節水かんがいシステムの開発 : パレスチナ自治区ヨルダン川西岸地区における適用可能性調査","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1586"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-16"},"publish_date":"2016-03-16","publish_status":"0","recid":"28268","relation_version_is_last":true,"title":["土のキャピラリーバリア機能を利用した節水かんがいシステムの開発 : パレスチナ自治区ヨルダン川西岸地区における適用可能性調査"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:58:11.680433+00:00"}
