Abstract: The experimental procedure to separate different species of soil selenium was proposed according to Jackson,Relationships between contents of 7 selenium species, distribution and availability to plants was studied in major soil in China,The results revealed that the concentration of water soluble selenium in alkaline soils are significantly higher than that in acid soils. Amount of unenveloped selenium form is correlated with total soil selenium. And amount of unavailable enveloped selenium form is interrelated with iron and aluminium in soil, which demonstrate that the unavailable enveloped selenium is mostly fixed by Fe oxides and Al oxides. The percentages of residue selenium vary slightly in different soils. The availabilities of selenium in soils in low selenium belt are similar to those in normal area. Therefore, low selenium content in plants results from low level of total soil selenium.
