Table list
Table 1 Physicochemical properties in mine soil and biochar amendments (units: mg kg-1). SOC: soil organic carbon, TN: total nitrogen, AN: available nitrogen, AP: available phosphorus, AK: available potassium, C/N: soil organic carbon/total nitrogen. pH and C/N were dimensionless units.
Table 2 Soil physicochemical properties and microbial mass in different treatments. Values are means ± standard error. Different letters indicate significant differences (P <0.05). *P <0.05, ** P <0.01, ***P <0.001. CK, C, C-N, C-M, C-M-N represent CK, biochar, biochar +N fertilizer, biochar + microbial agent, biochar +N fertilizer + microbial agent (N fertilizer and microbial agent did not refine to levels)
Table 3 Relative abundance of the dominant bacterial and fungal phyla (relative abundance >1%) in different treatments. Values are means ± standard error. Different letters indicate significant differences (P<0.05). * P <0.05, ** P <0.01, *** P <0.001. CK, C, C-N, C-M, C-M-N represent CK, biochar, biochar +N fertilizer, biochar + microbial agent, biochar +N fertilizer + microbial agent (N fertilizer and microbial agent did not refine to levels)
Table 4 Richness and diversity indices of bacteria (a) and fungal (b) communities in different treatments. Values are means ± standard error. Different letters indicate significant differences (P<0.05). * P <0.05, **P <0.01, *** P <0.001.
