Moderately resistant phosphorus forms in subtropical ultisol of Argentina
Communications in Soil Science and Plant Analysis, 2000Abstract The efficiency of phosphorus (P) fertilization may be improved through knowledge of soil P fraction changes with time. This study examined: i) the distribution of P fractions according to Hedley's fractionation scheme and ii) the sequential changes in soil organic P (OP) and inorganic P (IP) in a typical Kandihumult, under favorable conditions

Geomorphic Relationships of Oxisols and Ultisols on Kauai, Hawaii
Soil Science Society of America Journal, 1974Abstract A succession of Eutrustox‐Eutrorthox‐Gibbsiorthox‐Gibbsihumox occurring in northeastern Kauai, Hawaii, is shown to be a climosequence. These soils developed synchronously on basic lavas forming one geomorphic surface of Pleistocene age.
