Abstract

•Biochar significantly immobilized soil Cd and Zn over a 3-year period.•Compost and peat increased available Cd and Zn in soil.•Metal immobilization was attributed to the consistently higher pH and lower DOC concentrations in the biochar treatments.•DGT measurements were used to assess the short-term metal resupply kinetics.•The resupply of Cd and Zn from the solid phase to the soil solution was low (R ≤ 0.4) in all treatments.
