Also, compared to the Pzero treatment,
applied P fertilization significantly increased the
concentration of labile P and moderately labile P.
Additionally, applied P fertilization decreased acid
phosphatase enzyme activity and increased the total
relative abundance of microorganisms significantly in
P-rich soil, although they decreased in P-deficient soil.
Arbuscular mycorrhizal fungi (AMF) showed significant
positive correlations with soil labile P (P
