Keywords:

  • Aridisols, and soils of dry regions - in cool temperate deserts and warm deserts, at lower latitudes;
  • deserts, occupying about one-third of areas - of Africa and Australia, 11% of Asia, and 8% of the Americas;
  • soil-vegetation patterns - of arid regions, recognized at many scales;
  • Aridisols, occupying 12% of global land area - one-third of arid terrains, occupied by Aridisols;
  • aridic soil moisture regime - for soils at Phoenix, Arizona;
  • pedogenic processes in desert regions - and soil features;
  • Aridisols, most of them - with argillic horizons, on earliest Holocene and older landscapes;
  • horizons of calcium carbonate accumulation - below argillic and cambic horizons of Aridisols;
  • atmospheric deposition - major contributor of CaCO3 in many Aridisols;
  • Aridisol use, for agriculture - limited by lack of water
