Correlations of bacterial community composition based on the distribution of OTUs and Shannon diversity index with soil properties using the RELATE in the PRIMER V6 softwarea.
| Soil Properties | Correlation |
|
|---|---|---|
| Composition | Diversity | |
| pH | 0.19 | 0.30 |
| Organic C | 0.17 | 0.18 |
| Total N | 0.01 | 0.06 |
| C/N ratio | 0.01 | -0.14 |
| Microbial biomass C | 0.09 | 0.06 |
| Microbial biomass N | 0.05 | -0.08 |
aValues were Spearman’s correlation coefficient (ρ)between bacterial composition, diversity and soil properties. Values in bold are P ≤ 0.05.
