Abstract

SolI from subsurface wormcasts and from the lining of earthworm burrows had more water soluble phosphate than the surrounding soil at all soil depths sampled down to 250mm. The absolute effect of earthworm presence on water soluble phosphate concentration decreased markedly with depth. While earthworms increase soluble phosphate concentration down the soil profile, the availability of the redistributed phosphate is somewhat attenuated with depth, probably through its being resited in soil of greater phosphate absorbing power than that of the surface. Keywords: Earthworms, avatlable phosphate, phosphate distribution
