phosphate and exchangeable Al in the soil were determined in order to refer them for better soil management measures as a part of previous in vestigation on changes in physical and chemical properties of the soil abandoned after clearing forest. In addition some of physical and chemiical properties of the forest soil near the reclamation experiment site were investigated in the vertical extension for the same purpose. The level of available phosphate in the soil was higher in the DG and DN plots that were cleared by a rakedozer than in the EG and EN plots that were cleared by a bulldozer. Exchangeable Al in the soil was higher in the EG and EN plots than in the DG and DN plots. Changes in the levels of availavle phosphate and exchangeable Al in the soil were not clearly observed for the time course of 15 years after clearing forest. The vertical examination of some of the soil's physical and chemical properties in 2 forest sites revealed that soil nutrients tended to decrease steeply from the surface to a deeper layer, but reversely dispersion rate to increase. It was deemed that intensive soil management should be practiced to control soil erosion and to improve soil fertility if the land was reclaimed from the forest by a bulldozer.","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":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3751"}]},"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.
