Description
Summary:The need for sludges of controlled metal content for use in agricultural trials on the effects of metals in sewage sludges used on land is discussed. A method of producing sludges for experimental use by the pilot-scale treatment of metal-enriched sewage is described. The chemical extractability and availability to plants of metals in experimental sludges were compared with sludges obtained from sewage-treatment works. Results indicated that the experimental sludges would be suitable for use in agricultural experiments.
