Results of 8 field studies of long-term use of digested sewage on agricultural and disturbed lands are presented. The studies included: (1) response of corn grown on 3 soil types previously amended with annual sludge applications; (2) response of corn grown annually on Blount silt loam treated annually with sludge; (3) continuous corn on strip mine spoils treated with sludge; (4) differences in Cd and Zn uptake by various corn hybrids; (5) effects of cation exchange capacity on Cd uptake; (6) Cd uptake from Cd-spiked sludge by spinach; (7) response of chickens to Cd in feed; (8) Cd-induced growth depression and Cd accumulation in chicks as influenced by dietary modifications. No phytotoxicity developed from trace elements in sludge used annually as fertilizer. Crop uptake of heavy metals from soils containing residual sludge varied with species and varieties. Elevated levels of dietary Cd did not affect health of chickens, egg protection, nor composition of the eggs.
