Different profiles of soil phosphorous compounds depending on tree species and availability of soil phosphorus in a tropical rainforest in French Guiana.

ABSTRACT:

Background

The availability of soil phosphorus (P) often limits the productivities of wet tropical lowland forests. Little is known, however, about the metabolomic profile of different chemical P compounds with potentially different uses and about the cycling of P and their variability across space under different tree species in highly diverse tropical rainforests.

Results

We hypothesised that the different strategies of the competing tree species to retranslocate, mineralise, mobilise, and take up P from the soil would promote distinct soil ³¹P profiles. We tested this hypothesis by performing a metabolomic analysis of the soils in two rainforests in French Guiana using ³¹P nuclear magnetic resonance (NMR). We analysed ³¹P NMR chemical shif
