ABSTRACT
Study was carried out on local municipal dumping ground in Stożne near Kowale Oleckie in 2001 and 2002. The efficiency of grass mixtures in sodding was tested on a base of a two-factor field experiment: D – sewage sludge – three doses (20, 40 and 60 DM kg · 10 m-2). Five different grass mixtures and Festulolium in pure sowing were applied. Plant samples were taken in 2001 and 2002. After digestion of plants in microwave digester, iron, manganese, zinc, copper, cadmium, lead, nickel and cobalt contents were determined by means of AAS technique. Then intake of these elements by particular mixtures from 10 m2 area was calculated. It was found that sewage sludge from municipal dumping ground could be utilized for cover fertilization to form a sod. Mixtures No 4, 5 and Festulolium in pure sowing efficiently protected the heavy metal migration into the environment.
Key words: municipal dumping, heavy metals, grass species, sludge rate.
