Abstract: Magnesium is a necessary element for plant growth. There are many repo rts concerning about magnesium as a nutrient, but a few about soil magnesium pol lution. This paper introduced the present status of soil magnesium pollution in magnesite mining area, discussed the mechanisms of the pollution based on the ph ysical and chemical behaviors of magnesium in soil, summarized the corresponding amelioration techniques, and approached the main problems and the prospects in related researches.
