Immobilization And Phytotoxicity Reduction Of Heavy Metals In Serpentine Soil Using Biochar, I. Herath, P. Kumarathilaka, A. Navarantne, N. Rajakaruna, M. Vithanage
Biological Sciences
Purpose
Serpentine soils derived from ultramafic rocks release elevated concentrations of toxic heavy metals into the environment. Hence, crop plants cultivated in or adjacent to serpentine soil may experience reduced growth due to phytotoxicity as well as accumulate toxic heavy metals in edible tissues. We investigated the potential of biochar (BC), a waste byproduct of bioenergy industry in Sri Lanka, as a soil amendment to immobilize Ni, Cr, and Mn in serpentine soil and minimize their phytotoxicity.
Materials and methods
The BC used in this study was a waste byproduct obtained from a Dendro bioenergy industry in Sri Lanka. This …
