abstract = {Biochar has recently aroused great interest for the restoration of contaminated soils since
it improves soil properties and induces the immobilization of pollutants. This study evaluates the
use of biochar from plant pruning, applied as an amendment, for immobilizing metal(loid)s in a
highly contaminated soil as well as for reducing the phytotoxicity of these pollutants by promoting
natural revegetation. For this purpose, a bioassay with Trifolium pratense L. was used to test the
effectiveness of the soil amendment in greenhouse conditions. Three treatments were carried out
including soil contaminated with metal(loid)s (RA), and this soil was amended with biochar at
different dosage: 4% (RA4B) and 8% (RA8B). A non-contaminated soil (NC) from a nearby area not
affected by contamination was used as a control. The results show that biochar increased soil pH
by several units depending on the dose used, 8% being the most effective one. Biochar treatments
also reduced soluble and bioavailable forms of Zn and Cu. Likewise, phytotoxicity was significantly
reduced, promoting seed germination and biomass with plant growth values similar to the non-polluted soil. In light of the results obtained, the evaluation of the bioremediation potential of biochar
under field conditions can be considered.},
