文摘

Biochar with and without iron grit was added in a Cu-contaminated soil. Soil pore water: biochar with iron grit reduced its Cu2 + and Cu contents in year 2 Both amendments did not improve Giant reed and poplar growth. Shoot Cu concentration of poplar and Giant reed reached common values. Giant reed can increase the potential Cu leaching out of the root-zone.
