Dynamic effects of BFM and calcium fertilizer (A and B: CaO; C and D: CMP) treatment on the content of available Cd in soil under acidification conditions. CK: no BFM and calcium fertilizer added, 0.5BFM: added with 0.5% BFM, 1BFM: added with 1%BFM; CaO: added with CaO; CMP: added with calcium-magnesium phosphate fertilizer; 25 and 50 represent adding 25 and 50 kg/acre of calcium fertilizer, respectively.Error bars represent mean ± standard deviation (n=3); Significant differences between treatments throughout the incubation period are shown in Table S6 and 7.
