Growth, Biomass Production and Remediation of Copper Contamination by Jatropha curcas Plant in Industrial Wasteland Soil S. V. Ghavri and Rana P. Singh
The survival, biomass production and Cu remediation efficiency of Jatropha curcas L. was evaluated in Cu rich industrial wasteland soil (IWLS), collected from a local town, Sandila (Hardoi),Uttar Pradesh, India. The IWLS had high bulk density, Water Holding Capacity (WHC), pH, Electrical Conductivity (EC), Organic Carbon and NPK. The Cu and Mn contents in IWLS were about 3 and 2 fold higher than that in the normal field soil (control). Stem cuttings of the J. curcas clones (BTP-A, BTP-N and BTP-K) were planted in IWLS as well as the same amended with cowdung or sand. The percent survival, net elongations and biomass accumulation of J. curcas were decreased slightly in IWLS, as compared to the control soil. The translocation of Cu from soil to the plants was higher in IWLS grown plants, which was more pronounced in IWLS amended with cowdung. J. curcas clones BTP-N, showed better survival and Cu removal efficiency from IWLS.
