The results of this study clearly have shown that biochar application
to heavy metal contaminated soil has the potential for
heavy metal immobilization, reflecting on reducing metal
accessibility to the aboveground compartment of maize plants.
Moreover, the biochar addition significantly decreased the
bulk density and increased soil moisture content. Therefore,
biochar can be used to enhance metal phytostabilization of
contaminated soils as well as improved plant growth and some
soil physical properties.
