To assess these environmental problems, JIRCAS has conducted a collaborative research project from 1997 to 2004, entitled “Evaluation and development of methods for sustainable agriculture and environmental conservation”. The research was carried out in three intensive agriculture regions, i.e., Huan-Huai-Hai plain, Taihu catchments, and southern red soil area. Field experiments and monitoring identified croplands to be a major source of nitrogen loads to the environment at all the regions. Especially, large amounts of ammonia volatilization equivalent to more than one third of the rate of fertilized nitrogen were detected both at the paddy and upland fields. As options to reduce nitrogen losses from croplands without yield penalty, use of controlled release fertilizer, animal manure, and deep placement of fertilizer are recommended. These options are expected to contribute to reduce environmental impacts of Chinese agriculture, coping with a new direction in Chinese policy for “green society” that was recently incorporated in the 13th Five Year Plan of the government.","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":"2024-07-03"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2019-03-25"}],"filename":"jircas_working_report87-_29-39.pdf","filesize":[{"value":"811KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_working_report87-_29-39","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000334/files/jircas_working_report87-_29-39.pdf"},"version_id":"5642ae1e-caf7-4dd9-9fb2-0506eb19a665"}]},"item_30002_geolocation20":{"attribute_name":"位置情報","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"China"},{"subitem_geolocation_place_text":"中国"}]}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000334","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国際農林水産業研究センター","subitem_publisher_language":"ja"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"JIRCAS-CAAS農業科学技術研究協力の歩み : 20周年記念シンポジウムプロシーディングス"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000325","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_language":"zh-cn","subitem_relation_name_text":"国际农业环境研究进展与中日合作 : 农业生态系统中氮循环及其环境影响"}],"subitem_relation_type":"hasVersion","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000353","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_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"国際農業環境研究の進展と日中協力 : 農業生態系の窒素循環とその環境影響","subitem_title_language":"ja"}]},"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":"国際農業環境研究の進展と日中協力 : 農業生態系の窒素循環とその環境影響","item_type_id":"40039","owner":"74","path":["1719813337406"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-07-03"},"publish_date":"2024-07-03","publish_status":"0","recid":"2000334","relation_version_is_last":true,"title":["国際農業環境研究の進展と日中協力 : 農業生態系の窒素循環とその環境影響"],"weko_creator_id":"74","weko_shared_id":-1},"updated":"2025-03-05T01:02:27.997781+00:00"}
