  • Entisols - recently formed soils;
  • Entisols, soils that “have little or no evidence of development of pedogenic horizons”;
  • Entisols, of inert materials (quartz sand) - or exposure to pedogenic processes, diagnostic horizons typically absent;
  • Entisols, on land surfaces - very young, wet, dry, underlain by resistant initial material;
  • topolithosequences of Entisols - in floodplains of rivers, sandy soils (Psamments) of islands;
  • fragmentation of diagnostic horizons - by human manipulation of soils, profiles with no diagnostic horizons;
  • ubiquity of textural discontinuities - in Entisols formed in floodplains, water movement obstructed;
  • shallow Entisols in pinyon-juniper woodlands - on the Colorado Plateau;
  • classification of Entisols - soils without properties, diagnostic of the other orders;
  • suborders and great groups - in the Entisol order
