From: Increased plant productivity and decreased microbial respiratory C loss by plant growth-promoting rhizobacteria under elevated CO2

Figure 4

Plant-derived C inputs to soil (a) and specific microbial respiration (b).

Control: ambient CO2 and without bacteria addition; B: ambient CO2 and with bacteria addition; eCO2: elevated CO2 and without bacteria addition; B + eCO2: elevated CO2 and with bacteria addition. Error bars show standard error of the mean (n = 6). The same letters denote non-significant differences between treatments (P > 0.05).
