Differential Effects of Organic Ameliorants on the Reassembly of Bacterial Communities in Newly Amended Coastal Mudflat Salt-Affected Soil

Summary

Understanding the influences of organic ameliorants amendment on the soil microbiome is fundamental for the alleviation of environmental constraints in coastal mudflat salt-affected soils. However, how the compositional and structural diversity of the microbial community responds to different organic inputs, and key environmental determinants and relevant mechanisms driving soil microbiome reassembly in coastal agroecosystems have not been illustrated. In this study, field experiments were conducted to investigate the effectiveness and underlying mechanisms of sewage sludge (S) and sludge-based vermicompost (V) at different application amounts (0, 50, 100, and 200 t ha−1) on variations in the compositional and structural diversities of soil bacterial community in coastal mudflats.
