Those two profiles consisted of reddish brown soil, Ryukyu limestone and marl in descending oder. The marl and its weathering materials distribute in Okinawa Island occupying a predominant part of agricultural land. Reddish brown soil showed a good deal of similarity in the physical and chemical properties ofShimajiri mahjiwhich is locally called on dark-red soil derived from limestone. Futenma (O-38) soil showed a great deal of similarity in the mineral constituents ofShimajiri mahji. Azama (O-35) soil included illite, vermiculite and smectite as the major clay minerals which suggested contamination with marl. At Azama profile the unique light gray colored sediment underlay soft Ryukyu limestone of powder to granular materials. The pH and the value for organic and inorganic carbon were considerably higher and the CEC and exchangeable bases were less than half in the sediment than those in the other similar sediment. Illite, smectite, vermiculite and quartz were the major crystalline minerals of the sediment. It was considered that the dark gray colored marl had a tinge of white receiving an effect from Ryukyu limestone. At Futenma profile both the unique dark brown and yellowish brown colored sediments underlay had Ryukyu limestone. The second was observed as a transitional horizon of first. Quantitatively calcite was identified larger than quartz in the silt fraction of the second. In the clay fraction both sediments included illite, smectite and vermiculite as the main crystalline minerals which showed a great deal of similarity in those of the marl. Physical and chemical properties both sediments showed almost same tendency with the marl. It was assumed that the weathering materials dirived from the marl may turn dark reddish color which resemble in soil color ofShimajiri mahji. It is satisfactory to consider that changes of the sediments and sedimentation conditions had caused the difference in the marl which keep the certain mineralogical properties constant.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/3839"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
