Figure 2

Canonical correspondence analysis (CCA) considering the relative abundance of bacteria at the operational taxonomic units (OTUs) level and soil total C and N, concentrations of NH4+ and NO3− and pH in the rhizosphere of soybean grown in soil organic C (SOC)-poor and SOC-rich soils with different rates of N addition. The significance level of p < 0.001 was for the overall CCA model, and for the X and Y axes as well with 999 of permutations. Error bars on data points represent the standard error of the mean (n = 3).
