In areas where livestock production is active, the amount of livestock manure produced is also high, and therefore the production of cattle manure compost is also high. However, if there is not enough farmland in the region to meet the production volume, surplus compost is generated. In such areas, excessive application of manure to farmland and application to idle cultivated land are likely to occur. Nitrogen components applied as compost and chemical fertilizers leach out into the ground due to rainfall and other factors. If a large amount of nitrogen is transferred to groundwate, it may cause nitrate-nitrogen pollution of groundwater and eutrophication of the aquatic environment, so efficient nitrogen fertilizer application is required from both environmental and cultivation perspectives.\nIn this study, two lysimeters were used to evaluate the yield and nitrate-nitrogen leaching of Italian ryegrass, a forage crop, grown in soils treated with chemical fertilizer and cattle manure, respectively.\nThe results showed that nitrate-nitrogen leaching of lysimeter with cattle manure was suppressed to 56% of that with chemical fertilizer. Similarly, nitrate-nitrogen leaching per kg of dry matter yield of cattle manure-applied lysimeter was also reduced to 54% of that of chemical fertilizer. Even if the environmental impact is reduced by changing the nitrogen fertilizer application method, it would be difficult for farmers to make a choice if the yield is reduced, but the results of this study suggest that the same level of yield can be obtained by changing the application method from chemical fertilizer to cattle manure. In addition, the environmental impact was reduced to about half, and environment.al efficiency was also improved. These results suggest that it would be beneficial to reduce the use of chemical fertilizers, whose prices are rising, and to promote the effective use oflocal surplus compost in the cultivation of ltalian ryegrass as a forage crop.\nRegional Environmental System laboratory will continue to study the cultivation of forage crops using lysimeters and its environmental impact, and will continue to conduct research to obtain more practical knowledge.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34481/0002000656","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学地域資源創成学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Regional innovation, University of Miyazaki","subitem_publisher_language":"en"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"24338931","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"0000000106573887","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/0000000106573887"}],"affiliationNames":[{"affiliationName":"宮崎大学","affiliationNameLang":"ja"},{"affiliationName":"University of Miyazaki","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"戸敷, 浩介","creatorNameLang":"ja"},{"creatorName":"トシキ, コウスケ","creatorNameLang":"ja-Kana"},{"creatorName":"Toshiki, Kosuke","creatorNameLang":"en"}],"familyNames":[{"familyName":"戸敷","familyNameLang":"ja"},{"familyName":"トシキ","familyNameLang":"ja-Kana"},{"familyName":"Toshiki","familyNameLang":"en"}],"givenNames":[{"givenName":"浩介","givenNameLang":"ja"},{"givenName":"コウスケ","givenNameLang":"ja-Kana"},{"givenName":"Kosuke","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"31286","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00542424","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00542424"}]},{"creatorNames":[{"creatorName":"小金丸, 拓哉","creatorNameLang":"ja"},{"creatorName":"コガネマル, タクヤ","creatorNameLang":"ja-Kana"},{"creatorName":"Koganemaru, Takuya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"善福, 友陽","creatorNameLang":"ja"},{"creatorName":"ゼンフク, ユウヒ","creatorNameLang":"ja-Kana"},{"creatorName":"Zenfuku, Yuhi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-04-30"}],"filename":"地域資源紀要_p57-62.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","objectType":"fulltext","url":"https://miyazaki-u.repo.nii.ac.jp/record/2000656/files/地域資源紀要_p57-62.pdf"},"version_id":"39c3080c-be97-4f89-8504-243d9925eeaa"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"イ夕リアンライグラスの栽培における収量と窒素溶脱量に闘する研究 ー化学肥料と牛ふん堆肥を用いたライシメーター試験による比較研究ー","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イ夕リアンライグラスの栽培における収量と窒素溶脱量に闘する研究 ー化学肥料と牛ふん堆肥を用いたライシメーター試験による比較研究ー","subitem_title_language":"ja"},{"subitem_title":"Research on Yield and Nitrate-Nitrogen Leaching in Italian Ryegrass Cultivation : Comparative Study of Chemical Fertillizers and Cattle Manure Using Lysimeters","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"9","path":["83","69","455","1714106358748"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-29"},"publish_date":"2024-03-29","publish_status":"0","recid":"2000656","relation_version_is_last":true,"title":["イ夕リアンライグラスの栽培における収量と窒素溶脱量に闘する研究 ー化学肥料と牛ふん堆肥を用いたライシメーター試験による比較研究ー"],"weko_creator_id":"9","weko_shared_id":-1},"updated":"2025-01-16T04:59:31.473429+00:00"}
