The influence of fly ash (FA) applied alone and/or with sewage sludge (SS) on wheat (Triticum vulgare) grain yield, biomass production and soil properties was studied in a field experiment. The results showed that both FA and SS significantly increased grain yield and plant biomass. FA applied alone increased significantly soil pH and EC while FA applied together with SS did not significantly affect them compared to mono FA treatment. Soil pH and EC values increased with time in FA and FA-SS treatments. SS increased soil organic matter and total N content and SS applied together with FA increased also available soil B. From the plant nutrients tested only tissue N concentration was increased significantly in all treatments compared to control. Copper, Zn, Mn, Ni, and Pb at both available and total concentrations are significantly affected.
