Reports that organic wastes such as sewage sludges contain copper (Cu). How increased attention to environmental protection requires that wastes be treated with pathogen-eliminating procedures before application to farmland; Uncertainty whether such procedures affect the plant availability of Cu in the wastes; Details of 2-year field research, which investigated the effect of irradiation and composting on Cu availability in sludges and manure using a yield control approach.
