The usefulness of grass mixtures for biological reclamation of municipal dumping ground was investigated. Five mixtures and inter-genus hybrid Festulolium were sown on plots treated with 20, 40 and 60 t of sewage sludge per hectare. The highest biomass production was achieved on plots with Festulolium, and the best sodding was formed by Lolium perenne and Festuca rubra species. Dose of 40 t·ha-1 was the most favorable referring to sodding effect and biomass production under experimental conditions. Investigations point out to the usefulness of further study upon Festulolium.
