Thus, strategies to minimize losses are sought after.
The potential of Vigna subterranean commonly called Bambara beans for phytoextraction of copper in a crude oil contaminated soil was investigated. The contamination levels of crude oil in the soil for this pot experiment were 2, 4, 6, 8 and 10% (w/v). Amendments were added to increase the uptake and translocation of metal to aerial biomass.
The process of development of copper mine spoils has been examined taking spatial pattern of pH and organic matter as variables. Some other ecological factors like spoil physico-chemical properties, vegetation cover etc. have also been studied to understand the process of succession.
