Three differnt types of soil, all of which were distributed in OKINAWA district, were used as the test soil. They were called KUNIGAMI MAJI-soil (plot 1), JAGARU-soil (plot 2), NIIBI-soil (plot 3) respectively, and the soil grading was as follows : [table] The plots which were 0.335 square meters were set with a slope of 7 degrees. The simulated rain was dropped from a place 5 meters high above the surface of test soil for 10 minutes. Although the drop size distribution and terminal velocity of simulated rain were different from those of natural rain and the amount of rainfall was larger than that of natural rainfall, it may be of some clue to know the relation between soil loss and rainfall intensity on the natural farmland. The results of this experiment are shown as follows : 1. The detachiabillity of test soil is high in the order of NIIBI-soil, KUNIGAMI MAJI-soil, and JAGARU-soil. 2. The soil loss quantity by rainfall for NIIBI-soil and JAGARU-soil increases with the incrcease of rainfall intensity. But the soil loss quantity of KUNIGAMI MAJI-soil seems not to be affected much by rainfall intensity. 3. The relation between the soil loss quantity and the rainfall intensity for JAGARU-soil and NIIBI-soil will be expressed by an equation E=aI^b when they were plotted on a log-log graph. The value of a, b and the corelation coefficient between E and I are as following : plot 2 E=0.073 I^<1.504> r=0.728 plot 3 E=0.196 I^<1.188> r=0.894 where E : Soil loss g/0.335m^2 I : Rainfall intensity mm/10min. r : corelation coefficient. 4. The relation beteen the quantity of runoff and the rainfall intensity for the test soil will be the same as 3 above.","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/20.500.12000/4431"}]},"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.
