Partitioning of soil phosphorus among arbuscular and ectomycorrhizal trees in tropical and subtropical forests
Partitioning of soil phosphorus (P) pools has been proposed as a key mechanism
maintaining plant diversity, but experimental support is lacking. Here, we provided different
chemical forms of P to 15 tree species with contrasting root symbiotic relationships to
investigate plant P acquisition in both tropical and subtropical forests. Both ectomycorrhizal
(ECM) and arbuscular mycorrhizal (AM) trees responded positively to addition of inorganic
P, but strikingly, ECM trees acquired more P from a complex organic form (phytic acid). Most …
