Global residue inventory will reach an estimated 3.0 bil- lion tonnes in 2014. How to dispose the huge amount of bauxite residue is still a troublesome problem. Based on storage and utilization of bauxite residue, this paper discusses the problem of substrate amendment of bauxite residues, screening of tolerant plant species and microbe, and environment risk management in soil formation in bauxite residue. Further researches on soil formation of bauxite residues are proposed as well.
