Biochar amendments alter the bacterial (a) and fungal (b) diversity in the field experiment. Calculation of the Shannon index and Chao1 richness is based on OTU tables rarified to the same sequencing depth. Bars with different lowercase letters are significantly different (P < 0.05) by Bonferroni’s post hoc tests. CK, no fertilizer; CF, conventional fertilization; LB, low biochar with 2400 kg ha−1 year−1; MB, medium biochar with 7200 kg ha−1 year−1; HB, high biochar with 12,000 kg ha−1 year−1
