To paddy rice, chemical fertilizers (basal and top-dressing) and one of three livestock manures (cow manure, chicken manure, pig manure) were applied. These N sources changed N accumulation and natural ^<15>N abundance (δ^<15>N) in rice plants. Chemical fertilizers decreased and livestock manures increased the δ^<15>N values of rice plants, respectively. N accumulation from different N sources (soil, chemical fertilizers, livestock manure) calculated by the isotope mass balance method indicated that soil-derived N in rice plants with cow manure, chicken manure and pig manure was 5.1, 5.2 and 4.0g N m^<-2>, respectively. Estimated amounts of manure-derived N in rice plants were 1.7-2.3 g N m^<-2> by cow manure, 2.0-2.7 g N m^<-2> by chicken manure and 3.2-4.9 g N m^<-2> by pig manure. Estimated chemical fertilizer-derived N in rice plants was 0.5-1.5 g N m^<-2> by 2 g N m^<-2> basal application, 1.2-2.0 g N m^<-2> by 4 g N m^<-2> basal application and 1.3-1.8 g N m^<-2> by topdressing.
