Abstract

Trace metals in Lolium perenne L. grown on soil treated with ashes from a biomass incinerator Th. Leinoudi, C. Ah1 & F.-W. Klages Institute of Soil Science, University of Gottingen, Germany Abstract Ashes from a wood biomass incinerator were applied in a pot experiment using Lolium perenne L. (ryegrass) as the indicator plant. The utilization value of the ashes as fertilizer was tested, and the shoots of ryegrass were analyzed for the trace metals zinc, cadmium, lead, copper, nickel and cobalt, which had been determined in the ashes prior to application. Ryegrass was cultivated in pots filled with unpolluted soil to which certain amounts of known substances were added. Two series of substrates were created consisting of a single and a double dose of calcium oxide, an inorganic fertilizer and two ash types, roasted ash and cinder ash. These two ash types were by-products separated from the primary ash of the wood biomass incinerator following the exclusion of flue ash. Among the four ash treatm
