Ash disposal sites should be covered by a vegetation mantle immediately after they have been formed in order to protect them against water and wind erosion and to ensure an aesthetic view of the countryside. The vegetal cover of scarps and terraces of disposal sites and ash heaps plays a most important role in biological reclamation of disposal site. Botanical composition was affected by the kind of used waste. Utilization of municipal sludge was beneficial for tall fescue (Festuca arundinacea) growth, whereas the use of ash was more advantageous for red fescue (Festuca rubra). Among all sown plants tall fescue (Festuca arundinacea) was the most susceptible species to biological recultivation of furnace ash fertilized with sludge. A high diversification of reclamation mixture yielding depending on sludge and ash dose was found. The yield of reclamation mixture ranged between 0.15 and 11.81 t/ha-1, depending on the object. The highest reclamation mixture yield was generated on the object where sludge was used with ash in 3/4:1/4 weight ratio, and the lowest was obtained on the object where only ash addition was applied.
