Abstract

In pot trials, perennial ryegrass was grown in soil treated with sewage sludge containing 370 ppm Cd, 4940 ppm Zn and 450 ppm Pb or with equivalent amounts of Cd and Zn as sulphates. Levels of Cd and Zn in herbage in sewage sludge treatments were only about half as high as where the sulphates were used, and unlike in water culture did not increase progressively in subsequent cuts.
