Rainfall infilration and ponded infiltration of Kunigami Maaji Soil were measured. The result obtained are as follows. (1) In rainfall infiltration, the relationship between cumulative infiltration after ponding and time could be expressed by the Kostiakov\u0027s type of equation (D=CTn). (2) In rainfall infiltration, cumulative infiltration was sbout 10mm after 60 minute regardless of initial water content and rainfal intensity. (3) After 60 minute rainfall infiltration rate was 1/5 to 1/8 rate that of ponded infiltration rate. (4) It was found that on Kunigami Maaji regions, the most fundamental cause of soil erosion problem is decrease of infiltration rate by crust formation on the soil surface by raindrop impact.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学農学部"}]}, "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/20.500.12000/3774"}]}, "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": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
