Résumé
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, bacterial communities in VF and VG were phylogenetically less clustered and more influenced by variable selection and less by dispersal limitation. Soil pH was the most important edaphic variable mediating the changes in bacterial community assembly processes induced by agricultural intensification. Specifically, decreasing soil pH led to stochastic assembly of bacterial community. Soil pH was lower in more intensively managed lands, especially in case of VG (pH range: 5.86-7.42). Overall, agricultural intensification altered soil bacterial community assembly processes, which was associated with soil acidification. These findings may have implications for improving soil quality and agroecosystem sustainability.
