Differential mechanisms underlying responses of soil bacterial and fungal communities to nitrogen and phosphorus inputs in a subtropical forest.

ABSTRACT: Atmospheric nitrogen (N) deposition and phosphorus (P) addition both can change soil bacterial and fungal community structure with a consequent impact on ecosystem functions. However, which factor plays an important role in regulating responses of bacterial and fungal community to N and P enrichments remains unclear. We conducted a manipulative experiment to simulate N and P inputs (10 g N · m^-2 · yr^-1 NH₄NO₃ or 10 g P · m^-2 · yr^-1 NaH₂PO₄) and compared their effects on soil bacterial and fungal species richness and community composition. The results showed that the addition of N significantly increased NH₄ ⁺ and Al³⁺ by 99.6% and 57.4%, respectively, and consequently le
