Can the application of farm dairy effluent enhance cadmium leaching from soil?

The application of amendments such as farm dairy effluent (FDE) to soils which contain dissolved organic carbon (DOC) has the potential to increase cadmium (Cd) leaching through the formation of soluble organo-Cd complexes. However, the extent of Cd leaching loss is currently unknown. A lysimeter study measured Cd leaching from coarse and fine-textured Pumice soils amended with either FDE or single superphosphate (SSP) fertilizer.
