Soil pH: a key edaphic factor regulating distribution and functions of bacterial community along vertical soil profiles in red soil of pomelo orchard.

ABSTRACT:

Background

Soil microbes exist throughout the soil profile and those inhabiting topsoil (0-20 cm) are believed to play a key role in nutrients cycling. However, the majority of the soil microbiology studies have exclusively focused on the distribution of soil microbial communities in the topsoil, and it remains poorly understood through the subsurface soil profile (i.e., 20-40 and 40-60 cm). Here, we examined how the bacterial community composition and functional diversity changes under intensive fertilization across vertical soil profiles [(0-20 cm (RS1), 20-40 cm (RS2), and 40-60 cm (RS3)] in the red soil of pomelo orchard, Pinghe County, Fujian, China.

Results

Bacterial community composition was determined by 16S rRNA gene sequencing and interlinked with edaphic factors,
