Microbial Community Composition and Activity in Saline Soils of Coastal Agro-Ecosystems.

ABSTRACT: Soil salinity is a serious problem for agriculture in coastal regions. Nevertheless, the effects of soil salinity on microbial community composition and their metabolic activities are far from clear. To improve such understanding, we studied microbial diversity, community composition, and potential metabolic activity of agricultural soils covering non-, mild-, and severe-salinity. The results showed that salinity had no significant effect on bacterial richness; however, it was the major driver of a shift in bacterial community composition and it significantly reduced microbial activity. Abundant and diverse of microbial communities were detected in the severe-salinity soils with an enriched population of salt-tolerant species. Co-occurrence network analysis revealed stronger dependencies b
