Application of fertilizing materials (biosolids) on barren ground is often used for the introduction of organic matter and nutrients for plant growth on such soils. Two forage plant species were used: tall fescue (Festuca arundinacea) and sainfoin (Onobrychis viciifolia). F. arundinacea presented a higher degree of growth and density in comparison with O. viciifolia. The bioaccumulation degree of heavy metals (Fe, Cu, Cr, Ni, Zn and Pb) in the aerial tissue of plants was analysed. The addition of biosolids fertilizer caused a significant reduction of metal accumulation in tissues for both species. It may be concluded that the pollution caused by fl ash had a bad influence on the growth and development of O. Viciifolia plants, even lethal. Plants of O. Viciifolia gradually disappeared in the dry months of summer.en-USFly ashPhytoremediationBiosolidsPlantsHeavy metalsArticle
