Abstract
In this paper, two kinds of fluorine-contaminate soils, fluvo-aquic soil and paddy soil, were cultivated by nitrogen fertilizer. Then, we studied the various fluorine species in the cultivated soil by sequential extraction method, and study the effect of main components in nitrogen fertilizer on pH of soils. After adding nitrogen fertilizer, the pH value of soil would increase, which consequently led to the water soluble fluoride (Ws-F) increase. The result indicated that the pH value has significantly positive correlation with the content of Ws-F, and high pH value will make the fluorine contamination of soil become worse.
