Vertical Co-Evolution of Bacterial Communities and Sedimentary Geochemistry Across a Deep Regolith Profile in the Black Soil Critical Zone of Northeast China

Black soils are globally important for agricultural productivity, yet most studies of soil microbial communities are confined to the plow layer, leaving the deep regolith–bedrock interface largely unexplored. Here, we investigated bacterial diversity, community assembly, and co-occurrence networks along a 34-m regolith...
