Hardness and adhesion of the soil were significantly alleviated by the addition of hydroxy-Al. Formation of water stable aggregate and water permeability were promoted by hydroxy-Al. The addition of hydroxy-Al resulted in a slight decrease of pH values but tended to raise EC of the soil. It gave negligible effects on CEC, soluble phosphate, phosphate absorption coefficient in the soil. Green pod yield of bush type snap bean was favorably affected by the application of 2 to 6 tons of hydroxy-Al per hectare. Water intake rate that was determined in the field after harvesting the snap bean was found to improve with the hydroxy-Al application. It was deemed that the tested hydroxy-Al was applicable to improve physical properties of this kind of soil without much adverse effects, if measures are taken to mix it thoroughly with the soil and to give enough water or rain to leach down the salt yielded by the addition of hydroxy-Al.", "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/20.500.12000/3811"}]}, "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.
