This is a study which examines farm systems and soil loss control facilities by investigating soil loss from reclaimed farmland, rill erosion, factors contributing to soil loss, and functions of soil erosion control facilities. A gist of the study is as follows : 1. In soil loss surveys, soil loss from vegetated farmland and mulching farmland was negligible, whereas soil loss from bared farmland was high, with a high degree of muddiness even in water from large-scale sedimentation ponds. 2. In rill erosion surveys, the relation between the angle of inclination of the slope being eroded and the length of the slope can be shown in the following linear equation : U=14.69-0.612\u03b8 Where U=critical slope length (m) and \u03b8=degree of slope. The relationship of the coefficient of U and \u03b8 is 0.58 and not too high, because the conditions of the microtopograhy of the soil surface and the physical characteristics of the surface layer are contributing factors. 3. Pineapples, for about one year after planting, and sugarcane, for about half a year after planting, are both erodible crops, but later become non-erodible crops as they grow to form cover and their roots develops soil catch. 4. In case of a large-sclae farmland reclamation, such soil loss control measures should be taken as building temporary catchments for runoff water and prevention of direct flow into rivers of fluided particles. 5. As to soil precipitating functions of soil erosion control facilities, as shown in Table 3,soil precipitation function is high in channel type Fig. 17 (c), regardless of the rate of discharge.", "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/20.500.12000/3775"}]}, "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.
