Therefore, it is very important to study the crust formation mechanism for establishing the countermeasure for controlling soil crust. In this paper, approaches were made to examine the crust formation mechanism of Kunigami-mahji, Jahgaru and Shimajiri-mahji soils. Infiltration capacity of soil could be greatly reduced by the formation of crust. Hydraulic conductivity of crusted topsoil (0-0.5cm) was less than that of three soils mentioned above. The topsoils contained much more silt and clay particles. In vegetated plots, mulching protected soil surface from raindrop impact, so the formation of crust was delayed.","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/20.500.12000/3671"}]},"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.
