Bar-coded 454 GS-FLX titanium pyrosequencing of the 16S rRNA gene was used to evaluate the bacterial diversity of paddy soil samples managed under long term fertilizer practices. Since 1954, chemical fertilizers have been applied in the fields as N?P2O5?K2O and compost have been added as fermented rice straw at 0, 7.5, 7.5, 15.0, 22.5 and 30.0 Mg ㏊?¹ in APK, CAPK, UPKC750, UPKC1500, UPKC2250 and UPKC3000 treatments, respectively, while control did not receive any chemical fertilizer or compost. A total of 22646, individual sequences comprising 9842 operational taxonomic units (OTU) at 97% similarities with 75∼77% library coverage were obtained from the 7 soil samples. The 10 most abundant bacterial groups were the Proteobacteria, Chloroflexi, Acidobacteria, Bacteroidetes, Nitrospirae, Chlorobi, Actinobacteria, Planctomycetes, Firmicutes and Gemmatimonadetes. Significant changes in the diversity and evenness measures recorded and Venn diagram showed sharing of various species among the 7 soil samples. pair wise ∫-Libshuff analysis indicated significant differences (P ＜ 0.001) among the community structure of the samples. These results suggested that the changes in bacterial diversity and community structure of the paddy soil are influenced by long term fertilizer management practices.
