Fig. 2From: Soil pH: a key edaphic factor regulating distribution and functions of bacterial community along vertical soil profiles in red soil of pomelo orchardRelative abundance of bacterial communities in three soil depths. The relative abundance of dominant bacterial communities; A Phylum level; B Genus level; C Comparison of bacterial communities’ richness in different soil depths, i.e., RS1 (0–20 cm), RS2 (20–40 cm), RS3 (40–60 cm). The relative abundance of top 10 phylum/Genus has been shown, while the unclassified and less abundant were classified as othersBack to article page
