Fig. 7From: Effects of sweet pepper straw biochar on soil microbial communities and growth of continuously cropped cucumberPredictive analysis of bacterial (A) and fungal (B, C) function affected by SPSB treatment. CK (no biochar), S1 (2.5% w/w biochar + soil), S2 (5% w/w biochar + soil), S3 (7.5% w/w biochar + soil). The significant differences are determined by the Tukey test, with different lowercase letters indicating significant differences between groups (P < 0.05)Back to article page
