Soil acidification mediates changes in soil bacterial community assembly processes in response to agricultural intensification.

ABSTRACT: Agricultural intensification is known to alter the assembly of soil microbial communities, which regulate several critical ecosystem processes. However, the underlying ecological processes driving changes in microbial community assembly, particularly at the regional scale, remain poorly understood. Using 16S rDNA sequencing, we characterized soil bacterial community assembly in three land-use types with increasing land-use intensity: open fields cultivated with main crops (CF) or vegetables (VF), and greenhouses cultivated with vegetables (VG). Compared with CF, VF and VG altered bacterial community composition and decreased spatial turnover rates of edaphic variables and bacterial communities. Bacterial community assembly was primarily governed by deterministic processes; however, bacteri
