Variation in the soil pH under different treatments in the untrenched plots (A); variation in soil pH under different treatments in the trenched plots (B); and variation in fine root biomass under different treatments (C). Vertical bars represent standard errors (n = 4). Different lowercase letters indicate significant differences between treatments (P < 0.05). UTCK, UT4.0, UT3.25, and UT2.5 indicate the control, pH 4.0, pH 3.25, and pH 2.5 simulated acid rain in the untrenched plots, respectively; TCK, T4.0, T3.25, and T2.5 indicate the control, pH 4.0, pH 3.25, and pH 2.5 simulated acid rain in the trenched plots, respectively
