In this study, there was investigated on the chemical properties and cultivation adaptability of Kunigami Mahji soil improved by SOILHARD treatment. The results are summarized as follows. 1) There was suggested on the possibility to utilize as the liming material in the strong acidic soil areas. 2) There was suggested on the necessity to leach out bases from the improved soils with rainwater. 3) There was suggested on the necessity to increase nutrient absorption capacity, buffer action and available phosphate content by application of the organic matter like compost or barnyard manure.","subitem_description_type":"Other"},{"subitem_description":"沖縄県内における赤土砂流失の発生源対策法の一つとして，高分子凝集剤の「ソイルハード」による効果が期待されたので，土壌侵食を受けやすい強酸性土壌の国頭マージにそれを用いて粒状化した改良土を調製し，作物栽培前の改良土の化学性および作物栽培上の適性について検討した．改良土の化学性ではpH，交換性Ca含量および塩基飽和度等がいずれも著しく高く，可給態リン酸含量が低く，CEC値が望ましい値の半分以下で塩基バランスも著しく悪く，土壌の改善効果はほとんど期待できなかった．改良土の栽培適性では，調整過程の生石灰添加量が少なくて，水道水の洗脱処理回数の多いほどサントウサイの生育収量は高いことが認められたが，その生育状態には微量要素や苦土等の欠乏症の可能性が示唆された．いずれにせよ，改良土の化学性は，土壌改良資材として強酸性土壌地帯の石灰中和に利用できる可能性の他，降雨水による洗脱処理と共に堆肥等の有機物を併用して養分保持力や緩衝能や可給態リン酸含量等を高める必要性を示唆した．","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":"1996-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicPageEnd":"16","bibliographicPageStart":"11","bibliographicVolumeNumber":"31"}]},"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","filename":"477.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2015451/files/477.pdf"},"version_id":"e0cc53ec-88c2-459c-9388-248952e80e88"}]},"item_title":"ソイルハード処理による国頭マージ改良土の化学性と栽培適正","item_type_id":"15","owner":"1","path":["1642838327117","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-01-29"},"publish_date":"2009-01-29","publish_status":"0","recid":"2015451","relation_version_is_last":true,"title":["ソイルハード処理による国頭マージ改良土の化学性と栽培適正"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:37:46.381272+00:00"}
