Phytoremediation Of a Polluted Soil by Purple Plant (Tradescantia pallidaL.) Under Different Organic Amendments

Present investigation was performed to determine the ability of purple plant (Tradescantia pallida L.) for removing heavy metals from a contaminated soil particularly nickel, with aid different types organic amendments. Results metal content after application fertilizers were: maximum values (ppm) V, Cr, Ni, Mn, Cu, Zn, As, Mo, Cd, Pb and Ag were respectively: 275.437, 284.807 (control 1), 265.073, 1071.32, 60.0671 2), 77.8288, 9.5162, 8.5267 5.7943 7.5076 2) 37.8868 1). Whereas, minimum V: 104.644, Cr: 85.7222 (commercial fertilizer), Ni: 164.92, Mn: 711.155 (cow dung), Cu: 15.5141 Zn: 43.3929 As: 3.7819 Mo: 0.000 (plant residue composite bird manure), Cd: Pb: 4.1535 (bird manure) Ag: 2.9181 composite). This indicate that use amendment induce phytoremediation polluted soils.
