- The study aimed at determining changes in the contents of selected metals in the biomass of test plants due to fertilisation with fresh and composted sewage sludge, hard coal ash, and sludge-ash mixture, as well as liming at a background of mineral nutrition. The experimental design was a completely randomised arrangement with three replicates. The following factors were examined: fertilisation with organic and mineral materials (fresh sewage sludge; composted sewage sludge; hard coal ash; calcium carbonate) and mineral fertilisation (no fertilisation; NPK fertilisation). An application of sewage sludge, hard coal ash, and sludge-ash mixture significantly increased maize content of barium. Addition of hard coal ash into sewage sludge contributed to an increase in lead content determined in cocksfoot biomass harvested from the first and second cut, and barium in maize biomass. Soil liming significantly affected barium content the biomass of plants harvested from the first and second cut, as well as in maize biomass. NPK nutrition significantly increased barium concentrations in the biomass of test plants and maize.
