The effects of composting period and degree of maturity on production and optical characteristics of humic substance and structural features of humic acid in practically processed cattle manures were investigated. Beef cattle manure，which were mixed with bark litter and well composted (bark compost) by monthly turning for 5 and 12 months，were selected to evaluate effects of composting periods on the humification. Relative color density (RF value) of humic acid in bark composts increased with increase in the duration of composting. Optical characteristics and structural features of humic acids extracted by water and NaOH solution from four selected dairy and beef cattle manures，which showed completely different degree of maturity，were compared. Humic acids extracted by NaOH solution from dairy cattle manures，which were extremely high in moisture and not aerobically composted，were classified into the immature Rp-type and characterized by lignin-like structures from UV-VIS and FT-IR spectra. Aerobically fermented and well-matured beef cattle manure contained the humified B-type humic acid，which was characterized by carboxylic group and amide structures. These functional groups were more remarkable in the water-extracted humic acids than NaOH-extracted ones. It was concluded that practically well processed and matured cattle manure，which had been selected in the present study，contained highly humified organic matter compared to those reported in the previous studies，probably due to high temperature and its own heavy weight on a large scale.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本土壌肥料学会","subitem_publisher_language":"ja"}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本土壌肥料学会","subitem_rights_language":"ja"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00195767","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00290610","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":"李, 香珍","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"谷, 昌幸","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"相内, 大吾","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"小池, 正徳","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"倉持, 勝久","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":"hojokangen.pdf","filesize":[{"value":"643.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"hojokangen.pdf","url":"https://obihiro.repo.nii.ac.jp/record/604/files/hojokangen.pdf"},"version_id":"b124edcd-7f80-4412-b321-139b3980f7ef"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"牛ふん尿堆肥","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"圃場還元","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"腐植酸","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"フルボ酸","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"FT-IRスペクトル","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"cattle manure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"field application","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"humic acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fulvic acid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fourier-transform","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"infrared(FT-IR) spectra","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":"圃場還元利用されている実際的な牛ふん尿堆肥に含まれる腐植酸およびフルボ酸の化学的特徴","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"圃場還元利用されている実際的な牛ふん尿堆肥に含まれる腐植酸およびフルボ酸の化学的特徴","subitem_title_language":"ja"}]},"item_type_id":"2","owner":"12","path":["5"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-11-11"},"publish_date":"2010-11-11","publish_status":"0","recid":"604","relation_version_is_last":true,"title":["圃場還元利用されている実際的な牛ふん尿堆肥に含まれる腐植酸およびフルボ酸の化学的特徴"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-02-28T03:04:32.981504+00:00"}
