The objective of this study was to assess to what extent the
application of different concentrations of biochar to metalcontaminated
soils affected the bioavailability of Cd, Zn and
Pb and the biomass production of rapeseed (Brassica napus L.).
We selected rapeseed as the study plant because this species
belonging to the Brassicacea family has received much
attention due to its fast growth, elevated fully-harvestable
biomass production and high energy potential while being
tolerant to high metal concentrations
