The soil phosphorus content (mg kg.−1) and distribution (%) of different phosphorus fraction components (H2O-P, NaHCO3-Po, NaHCO3-Pi, NaOH-Po, NaOH-Pi, dilute HCl-P, concentrated HCl-Po, concentrated HCl-Pi, concentrated H2SO4-P) among different treatments (CK: soil; P. moraviensis: soil incubated with strain P. moraviensis; B. safensis: soil incubated with strain B. safensis; F. pallidus: soil incubated with strain F. pallidus) in pot experiment. Compared with CK, the asterisk on the same phosphorus fraction components of each strain showed significant differences (* P < 0.05, ** P < 0.01)
