Biplot of ten bacteria of relatively high abundance (in phylum level) and 13 corresponding environmental variables in CCA ordination of rice paddy soil. Biplot vectors shown represent the major explanatory environmental variables. SMC soil moisture content, TN soil total nitrogen, SOM soil organic matter, AP soil available phosphorus, AK available potassium, SAK slowly available potassium, PW_DOC pore water dissolved organic carbon, PW_DIC pore water dissolved inorganic carbon, \(PW\_SO_{4}^{2 - }\) pore water sulfate, \(PW\_NO_{3}^{ - }\) pore water nitrate, \(PW\_NO_{2}^{ - }\) pore water nitrite, \(PW\_NH_{4}^{ + }\) pore water ammonium, PW_TP pore water total phosphorus
