Effect of different cultivation techniques on microbial community catabolic diversity as evaluated by: the Shannon's diversity index (H) and average well-color development (AWCD590) in the Biolog EcoPlate incubated for 168 h (P < 0.05). Soil collected before maize sowing: DSBS, direct sowing; RTBS, reduced tillage; FTBS, full tillage; CRBS, crop rotation; Soil collected in flowering stage of maize growth: DSF, direct sowing; RTF, reduced tillage; FTF, full tillage; CRF, crop rotation. Treatment means separated by different letters are significantly different (P < 0.05).
