| Outline of Final Research Achievements |
Impacts of long term animal manure application on soil bacterial diversity were analyzed. The results indicated that the manure application increased the values of diversity indexes, while phylogenetic composition at phylum level was not affected by animal manure application. Impacts of long term organic fertilizer application were also examined. the decrease of relative abundance for Actinobacteria, Firmicutes, Gemmatimonoadetes, and Nitrospirae in the field of long term chemical fertilizer application, suggesting the loss of geocheical function by chemical fertilizers.
