What is Manure application effects on subsoils: Abundant taxa initiate the diversity reduction of rare bacteria and community functional alterations about?

Manure application is a significant agriculture practice that can affect the microbial community structure in both topsoil and subsoil. However, how the abundant and rare taxa in the soil profile respond to surface manure application and their ecological roles at different soil depths remain unknown. Based on a soil mesocosm experiment, we used amplicon sequencing and high-throughput quantitative-PCR array to characterize the bacterial community composition and functional traits across soil profiles. Results showed that the relative abundance and diversity of rare taxa increased in the topsoil but decreased in the 40–60 cm soil, where the relative abundance of abundant taxa increased after manure application. Evidence from network analysis, niche width and 16S rRNA operon (rrn) copy number suggest that abundant taxa in subsoils had a greater competitivity for resource mining than rare taxa. Regarding resource utilization strategies, microbial communities under manure treatment preferred to utilize recalcitrant carbon (C) and inorganic phosphorus (P) in the topsoil and labile carbon and organic phosphorus in the subsoil compared with non-manure application.
