Despite low concentrations of factors associated with fluoride binding in soils, the soils investigated in this study showed high soluble fluoride retention rates varying from 94.9 to 98.4% even at very high fluoride application rates. It was concluded that the illuvial (B) horizon and to a lesser extent, the mineral (A) horizon were responsible for most of the fluoride fixation. With increased time it was found that less fluoride was leached and the bonding between fluoride and soil binding factors was increased.
