Organic C, nitrogen, available P etc. increased in soil due to sewage sludge as well as fly ash amendments. The present report examines the levels of essential (Cu, Zn, Cr and Ni) and nonessential heavy metals (Cd and Pb) in sewage sludge, fly ash and in its mixtures. The report also examines the concentrations of heavy metals in different test plants grown at different rates of fly ash, sewage sludge and their mixtures.en-USSewage sludgeFly ashTechnical Report
