Leaching is being implemented as a measure to remove the salt in the farmland. However, it does not work well in the central part of the farmland far from the drainage channel and the vicinity of the water channel where the salinity concentration in the soil remains high and the groundwater level remains high because the drainage function is low. We introduced shallow subsurface drainage, which is generally used in the farmland in Japan, as a counter measure to salinity into this region. We adopted a new mole drain or Cut-drain system, which is an inexpensive drainage improvement technology developed in Japan. \nWe determined that the Cut-drain machine is greatly restricted under dried soil conditions in the arid areas. When using a Cut-drain system, it is desirable that the soil surface becomes dry and the soil in the lower layer holds enough water to have plasticity after the leaching and even after the rainy season. The application of the Cut-drain for leaching in Uzbekistan was confirmed, because it was proven by Cut-drain with the formation of the cavity and the discharge from the outlets partially. However, it requires improving measures against the collapse of the cavity at the time of leaching and the increase of leaching effect.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"The above article was translated and reprinted from “Water, Land and Environmental Engineering, Vol. 83, No. 7, pp. 541-544 (2015)”, published by the Japanese Society of Irrigation, Drainage and Rural Engineering.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-05-01"}],"filename":"jircas_working_report88-_65-74.pdf","filesize":[{"value":"624KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_working_report88-_65-74","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000236/files/jircas_working_report88-_65-74.pdf"},"version_id":"cbfb7eac-b20c-4617-a773-e2df725f35c1"}]},"item_30002_geolocation20":{"attribute_name":"位置情報","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"Uzbekistan"},{"subitem_geolocation_place_text":"ウズベキスタン"}]}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000236","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"Development of subsurface drainage and water-saving irrigation technology for mitigation of soil salinization in Uzbekistan"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000227","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"book part","resourceuri":"http://purl.org/coar/resource_type/c_3248"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1341-710X","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11159468","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"Mole-drain","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"High groundwater level","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Subsurface drainage","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Salt-accumulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Desalinization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dryland","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Uzbekistan","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Trial of Desalinization by Using a Mole-Drain in the Republic of Uzbekistan","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"A Trial of Desalinization by Using a Mole-Drain in the Republic of Uzbekistan","item_type_id":"40039","owner":"74","path":["1713762830049"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-01"},"publish_date":"2024-05-01","publish_status":"0","recid":"2000236","relation_version_is_last":true,"title":["A Trial of Desalinization by Using a Mole-Drain in the Republic of Uzbekistan"],"weko_creator_id":"74","weko_shared_id":-1},"updated":"2024-05-28T01:45:53.702643+00:00"}
