Short summary
Nitrogen (N) fertilization has received worldwide attention due to its effects on soil functions. However, soil multifunctionality and the underlying microbial mechanisms remain unclear. Therefore, we carried out in situ field and incubation experiments. We propose that straw return with 25 % N fertilizer reduction may achieve high soil multifunctionality by regulating the soil C:N ratio and N input level and specific keystone taxa-driven community contributions to soil functions.
