Climate change is reshaping ecosystem components and functions across soil profiles. In this study, we examined the effects of altered precipitation and nighttime warming on soil microbial communities in both topsoils (0–20 cm in depth) and subsoils (20–50 cm in depth) in a long‐term field experiment in Inner Mongolia, China. Unexpectedly, moisture, belowground net primary production, and NO 3 − content in subsoils were all af...
