Effects of different wood ashes on the solubility of cadmium in two boreal forest soils
In this study the fate of wood ash-derived cadmium (Cd) in forest soils was monitored in a field experiment and in a subsequent incubation experiment in the laboratory. The aim was to assess the distribution of cadmium between various pools differing in their bioavailability. In the field experiment...
