Phytoremediation Potential of Selected Energetic Plants （Miscanthus giganteus L. and Phalaris arundinacea L.） in Dependence on Fertilization

This paper present the influence of fertilization in cultivation Miscanthus giganteusL. and Phalaris arundinaceaL. in the process of phytoremediationof Cd, Ni and Zn. Research show that after first year of vegetation, Cd (0.344 mg·kg dry mass (d.m.)) and Zn (29.47 mg·kg d.m.) were the most absorbed metals by the biomass of Miscanthus giganteusL. grown on soil fertilized with municipalsludge (OW). However, in the case of the reed canary grass, the correlation can be attributed to the Ni (3.76 mg·kg d.m.) and Zn (122.6 mg·kg d.m.). In turn, after the second year of vegetation, all of the tested metals are characterized by a lower absorption as compared to the first year. In the case of reed canary grass, Cd and Zn content in the biomass after the second year of vegetation was similar to the control, while the Ni concentration was lower in relation to the control. In the case of Miscanthus giganteusL., it was observed that the concentration of Ni and Zn in the biomass after the second year of vegetation was similar to the control, while the Cd content varied in dependence on the applied fertilizer.
