Soil Science Society of America Journal Abstract A

A general tendency for the apatite content to increase with depth was noted. This increase is shown to parallel the profile distribution of acid-soluble phosphorus in these soils. There was a close correlation between the total phosphorus content of the sand and coarse silt and the percent of apatite as determined by this method.
