CK0, soil without treatment; CK1 and CK2, soil incubated at 25°C for 7 and 14 days, respectively; Itu1 and Itu2, soil treated with iturin A at 25°C for 7 and 14 days, respectively; Fen1 and Fen2, soil treated with fengycin at 25°C for 7 and 14 days, respectively. Data are means ± SD. Different letters in the same column indicate significant difference at P < 0.05 level by the least significant difference (LSD) test.
