Abstract
Diffusive gradients in thin-films (DGT) is a new technique which uses a simple passive assembly to measure quantitatively in situ fluxes from solid phase to solution and concentrations of dissolved components in sediments and water. Its potentially wide application to soils will be investigated for phosphate and trace metals by establishing the dependency of theoretical relationships on soil water content. DGT's ability to make measurements of high spatial resolution will be exploited to examine concentrations and fluxes within the rhizosphere. The usefulness of this simple in situ measurement of available metal as a surrogate for the bioavailable fraction, will be tested by pot experiments.
