Fluorine Distribution with Depth in Relation to Profile Development in Illinois1

  1. J. A. I. Omueti and
  2. Robert L. Jones2



Fluorine content increases with depth, evidently in response to pH-related absorption of F that has weathered from minerals in all size fractions of the upper solum. This relationship with soil colloids creates depth distribution characteristics of F that closely follow soil development trends that are especially well expressed by clay content. Fluorine attributed to organic matter in A and B horizons amounted to 9 µg/g of organic matter.
