Iron-oxidizing strain (FeOB) and iron modified biochars have been shown arsenic (As) remediation ability in the environment. However, due to the complicated soil environment, few field experiment has been conducted. The study was conducted to investigate the potential of iron modified biochar (BC-FeOS) and biomineralization by a new found FeOB to remediate As-contaminated paddy field. Compared with the control, the As contents of G(B)(BC-FeOS), G(F) (FeOB), G FN (FeOB and nitrogen fertilizer), G(BF) (BC-FeOS and FeOB) and G(BFN) (BC-FeOS, FeOB and nitrogen fertilizer) treatments in pore water ...
