fall and the nutrient returns in a forest were studied. The results obtained from five plots in natural evergreen broadleaved forests at Northern Okinawa Island in the period May 3,1996 to May 1,1998. Annual rates of total litter fall ranged from 7328 to 12700kg ha^<-1> a^<-1> in the first year, and from 5577 to 8073kg ha^<-1> a^<-1> in the second year, with great variation between the two years being related to the effects of the stronger typhoon No. 12 from August 11 to 12,1996. And the foliage litter fall contributed the greatest amount, about 63.7% averagely ranging from 54.6 to 78.8% of the total litter mass, and peaked in March and August, respectively. The results from this investigation indicated that the annual mean litter fall rate was positively correlated with stem volumes, mean D.B.H. and mean height of the stand, however, was negatively correlated with the stand density and neither related to the stand basal area. The annual amounts of nutrient returned by litter fall in the sampling stands were, N from 61.3 to 128.2kg ha^<-1> a^<-1>, P from 2.8 to 6.0kg ha^<-1> a^<-1>, K from 20.8 to 44.5kg ha^<-1> a^<-1>, Ca from 40.0 to 117.9kg ha^<-1> a^<-1>, Mg from 13.3 to 28.3kg ha^<-1> a^<-1>, S from 7.0 to 14.6kg ha^<-1> a^<-1>, Na from 8.4 to 17.2kg ha^<-1> a^<-1>, Al from 8.6 to 16.6kg ha^<-1> a^<-1>, Fe from 0.6 to 1.4kg ha^<-1> a^<-1>, and Mn from 2.6 to 5.4kg ha^<-1> a^<-1>, respectively. However, the annual nutrient returns for microelements such as Cu, Zn, Mo, Co and B were very little. Within the annual cycle, monthly nutrient fall was the most in August and the least in January, and the former was 12&acd;31 times more than the latter. Spring and summer (from March to August) was most important, accounting for over 70% of the nutrients.","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/20.500.12000/3692"}]},"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.
