ABSTRACT Phosphorus (P) availability constrains plant productivity in forest ecosystems, with soil functional genes involved P cycling playing a pivotal role regulating its availability. However, the effects of climatic gradients on and remain unclear. We collected 90 samples from subtropical Chinese fir plantations along north‐to‐south gradient to evaluate impact phoD ‐harboring bacteria availability, employing high‐throughput sequencing biologically based approach. The lowest organic was observed mid (0.35–1.48 mg kg −1 ) region compared south (1.27–2.69 north (0.81–2.34 ), inconsistent trends inorganic P. Lower diversity stronger competition subtropics, higher collaboration subtropics. Actinobacteria positively correlated strongest predictor (Increase mean squared error = 17.63%). Mechanistic modelling indicated that variations nutrients pH altered among dominant species, thereby enhancing acid phosphatase activity shifting mineralization. Our findings highlight increased may enhance P‐poor soils under climate warming. Collectively, this study offers novel insights into how impacts plantation soils.
