The storage of waste dump gravely deteriorates the soil’s physical, chemical and biological properties, both in the storage area and the surrounding zones. In time, serious perturbations may occur in the biocenosis from the surrounding ecosystems, through the sweeping away of the inorganic matter or through precipitations. The main problem in this case is to find the most suitable phytoremediation method for these waste dumps, by sowing plant species (grasses), in order to stop the erosion generated by wind and rain. Establishing a herbaceous “carpet” , in time, is very difficult, because the waste dump contains no organic matter, has a weak water retaining capacity and has a high bareness index. The purpose of this study was the experimentation of a method of cultivating the waste dumps using alfalfa, fescue and biosolids as fertilizers.
