BC: biochar; GG: G. geotrichum; ND: not detected or not determined in the samples. Each value is expressed as mean±SD of six replicates from three independent experiments. The data were analyzed by ANOVA using SAS. Values in a column followed by different letters show the significant differences (P<0.05) among treatments based on DMRT
