The contribution of microbiota to soil taxonomy and multifunctionality variation through vertical soil profiles in paddy soils_nifh

Soil microbiomes play critical roles in maintaining ecosystem services and functioning from the superficial layer to subsurface, including soil formation (pedogenesis), plant productivity and biogeochemical processes, especially for agriculture system. Despite their ubiquitousness along soil profiles, the contribution of soil microbiomes to pedological characteristics and differentiated multifunctionality among distinct soil types with depth are still poorly understood. Here, we sampled three types of paddy soils (Stagnic Anthrosols) through soil profiles at a local scale, and investigated the variations in community assembly of soil bacteria/diazotrophs and in multi-nutrient cycling with depth among the varied soil types.
