Keywords:

  • Oxisols, low activity soils - sandy loam, or finer-textured mineral soils, low apparent cation exchange capacity (CEC) clay;
  • Oxisol profiles, and low bulk density - between 1.0 and 1.3 g cm−3;
  • Oxisols, with isothermic or isohyperthermic soil temperature regimes - some Oxisols with hyperthermic, thermic or isomesic regimes;
  • Oxisols, and vegetation - tropical rain forest, scrub and thorn forest, grassland savanna;
  • Oxisols, and fluctuating water table - soil surface, localized iron concentration;
  • melanization and humification - in all Oxisols;
  • uses of Oxisols - relative to most other soils, most Oxisols chemically infertile;
  • Oxisol-dominated landscapes - level, facilitating use of large equipment;
  • suborders and great groups - in the Oxisols order;
  • Oxisols, nonsandy mineral soils - with few weatherable minerals, and low CEC
