Phytostabilization potential of Pb mine tailings by two grass species, Thysanolaena maxima and Vetiveria zizanioides
Pot and field experiments were conducted to elucidate the phytostabilization potential of two grass species (Thysanolaena maxima and Vetiveria zizanioides) with respect to lead (Pb) tailing soil. Three fertilizers (Osmocote® fertilizer, cow manure, and organic fertilizer) were used to improve the ph...
