Abstract Chicory was cultivated in a pot experiment using two soils of different pH. Treatments were NPK, fly ash (pH 8) + NP and fly ash (pH 12) + NP, respectively. Another series of pots received heavy metals in soluble form additionally to the described treatments. It was observed that fly ash causes generally a decrease in Zn, Cd, Ni and Cu concentrations of chicory. The reduction occurs both for the metals naturally present in the soil and, to a greater extent, for those added as salts. This effect is more evident when fly ash at pH 12, rather than that at pH 8, was used. The increase of soil-pH through the fly ash addition is the major factor decreasing heavy metal availability. It was observed that potassium originating from fly ash is not available for crop uptake.
