Effect of Bacillus on soil available nutrients after being treated with root exudates of F. bidentis.
| Strains | C0 | C1 | C2 | C3 | |
|---|---|---|---|---|---|
| AP | B. megaterium | 28.14 ± 2.95a | 32.39 ± 2.93a | 32.02 ± 3.61a | 32.64 ± 3.47a |
| B. frigoritolerans | 25.01 ± 1.63c | 28.25 ± 2.57c | 42.42 ± 3.24b | 61.24 ± 3.27a | |
| AN | B. megaterium | 114.36 ± 6.51d | 165.8 ± 1.56c | 253.4 ± 15.28b | 342.5 ± 13.93a |
| B. frigoritolerans | 94.3 ± 1.88a | 96.53 ± 0.98a | 98.47 ± 0.8a | 99.04 ± 0.83a |
AP, Available phosphorus; AN, Available nitrogen; C0, sterile water; C1, 20×the volume of concentrated root exudates; C2, 40×the volume of concentrated root exudates; C3, 60×the volume of concentrated root exudates. Different lowercase followed after values in the same line indicate that the same strain with different concentrations root exudates has significant differences at the p <0.05 level. The values are shown as mean ± standard deviation.
