Soil dressing using the Niibi, sandy soil, has been expected as one method to improve the physical properties of the Jaagaru soil, the trafficability of tractors and the soil tilth. It was the purpose of this paper to examine an effect of this soil dressing. Some traction tests by MF178 tractor (power : 78PS/1800rpm, weight : 3125kg), were done in the four test fields that were changed the volum content of Niibi to 0%, 10%, 20% and 30%. There were no remarkable relationships between the volume content of Niibi and draft, slippage and sinkage. So, it was concluded that the trafficability of tractors in Jaagaru fields was not improved by the soil dressing. The reasons why the effect of soil dressing to the trafficability was so small remained as a problems to be solved.", "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/20.500.12000/4032"}]}, "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.
