phosphorus fertilisation, but it is unknown if fertilisation is
a short or long term effect on P availability. Past research
suggests that P cycling in soils with high P sorption capacity,
such as Andisols, was through organic pathways. We studied leaf
P and soil P fractions in a tropical forest Andisol for 3 years
after fertilisation with triple super phosphate. Leaf P
concentration and labile P remained high after fertilisation.
Fertilisation had increased all the inorganic P fractions over
the length of the study, while organic P fractions had not. The
results suggested that the organic P fractions had a reduced
role as a source of labile P after f
