Figure 3. Comparison of the soil bacterial communities at the phylum level in the Moso bamboo plantation under all treatments.

The relative abundances of the dominant bacterial groups in the soil differed depending on the nitrogen deposition and management practices. Relative abundances are based on the proportional frequencies of DNA sequences that could be classified. CN0: conventional management with no added N; CN30: conventional management with 30 kg N∙ha⁻¹∙yr⁻¹; CN60: conventional management with 60 kg N∙ha⁻¹∙yr⁻¹; CN90: conventional management with 90 kg N∙ha⁻¹∙yr⁻¹; IN0: intensive management with no added N; IN30: intensive management with 30 kg N∙ha⁻¹∙yr⁻¹; IN60: intensive management with 60 kg N∙ha⁻¹∙yr⁻¹; IN90: intensive management with 90 kg N∙ha⁻¹∙yr⁻¹.
