In Miyakojima, groundwater contamination due to the excessive application of artificial fertilizer, the use of unripe compost and the open air storage of domestic animal excrement is of great concern. This paper attempts to clarify the current situation with regard to the disposal of stock excrement from farms and quantify the amount of agricultural waste biomass in existence in Miyakojima city, excluding the former Hirara city, and Gusukube and Irabu townships. According to the results of the questionnaire, family-owned farms want to use the waste biomass for the maintenance of soil fertility more than they do at present. However, while the construction of roofed compost facilities is ideal, the problems remains that most farms. still rely on open air composting. Family-owned farms tend to become dependent on artificial manure as it\u0027s immediate effects in improving soil fertility are more advantageous than the slower effects associated with the use of compost. However, as the unit cost of artificial fertilizer is greater than that of manure, its continued use is financially crippling for family-owned farms. Though family-owned farms actively desire to utilize the agricultural waste biomass to maintain soil fertility, farms with large numbers of stock are yet to provide suitable arrangements for the treatment of the excrement and, therefore, are unable to effectively apply it to the maintenance of soil fertility.", "subitem_description_type": "Other"}, {"subitem_description": "論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "沖縄農業研究会"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Okinawa Agriculture Research Society"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "1344-1477"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00083297"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "沖縄農業"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "2008-08", "bibliographicIssueDateType": "Issued"}, "bibliographicIssueNumber": "1", "bibliographicPageEnd": "46", "bibliographicPageStart": "37", "bibliographicVolumeNumber": "42"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "670.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2015693/files/670.pdf"}, "version_id": "129261ca-f564-4935-8f77-f2376478b87a"}]}, "item_title": "島嶼地域におけるバイオマスの農業への利活用の可能性　―宮古島におけるアンケート結果を中心に―", "item_type_id": "15", "owner": "1", "path": ["1642838334192", "1642838412624"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002015693", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-12-24"}, "publish_date": "2009-12-24", "publish_status": "0", "recid": "2015693", "relation": {}, "relation_version_is_last": true, "title": ["島嶼地域におけるバイオマスの農業への利活用の可能性　―宮古島におけるアンケート結果を中心に―"], "weko_shared_id": -1}
