The hydrophobic fertilizers were prepared by mixing finely-ground chemical fertilizers (SP: super-phosphate, CC: calcium carbonate, and NP: a mixture of ammonium phosphate and ammonium sulfate) with hydrophobic silica (8wt.%) to make a moisture-proof cover that could float on the slurry. Laboratory trials were carried out for 13 days using a pilot-scale device. The hydrophobic fertilizers composed of SP and NP reduced NH3 and CH4 emmisions from the digested slurry remarkably. However. we did not observe any suppression of gases when we applied the hydrophobic fertilizer composed of CC. The effect of the novel covers on the emissions of greenhouse gases and other polluting gases varied with the types of chemical fertilizers depending on acidity-alkalinity, solubility and ability to adsorb these gases. The hydrophobic fertilizer coverings and partial dissolution of their nutritional constituents affected the fermentation process of dairy slurry during storage and consequent gas emissions.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"廃棄物資源循環学会","subitem_publisher_language":"ja"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.3985/jswme.19.175","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"廃棄物資源循環学会","subitem_rights_language":"ja"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10414685","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18831648","subitem_source_identifier_type":"PISSN"}]},"item_2_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":"坂本, 直久","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"谷, 昌幸","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"小池, 正徳","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"倉持, 勝久","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"岸本, 正","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"梅津, 一孝","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-30"}],"displaytype":"detail","filename":"choryuu.pdf","filesize":[{"value":"895.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"choryuu.pdf","url":"https://obihiro.repo.nii.ac.jp/record/544/files/choryuu.pdf"},"version_id":"be8ba92f-522a-4796-9621-4786402b5662"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"畜産廃棄物","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"スラリー貯留槽","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"アンモニア","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"温室効果ガス","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"環境汚染","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"animal waste","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"slurry store","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ammonia","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"greenhouse gas","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"environmental pollution","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"貯留中の乳牛ふん尿スラリーから発生する環境負荷ガスを抑制する撥水加工肥料資材の開発と評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"貯留中の乳牛ふん尿スラリーから発生する環境負荷ガスを抑制する撥水加工肥料資材の開発と評価","subitem_title_language":"ja"}]},"item_type_id":"2","owner":"12","path":["5"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-03-10"},"publish_date":"2011-03-10","publish_status":"0","recid":"544","relation_version_is_last":true,"title":["貯留中の乳牛ふん尿スラリーから発生する環境負荷ガスを抑制する撥水加工肥料資材の開発と評価"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-02-28T03:06:14.062958+00:00"}
