  • These are CaCO₃-containing soils of arid regions that exhibit subsurface horizon development.
  • They are characterized by being dry most of the year and limited leaching.
  • They contain subsurface horizons in which clays, calcium carbonate, silica, salts, and/or gypsum have accumulated.
• Inceptisols soil
  • It exhibits minimal horizon development.
  • They are more developed than Entisols, but still lack the features that are characteristic of other soil orders.
  • A sizable percentage of Inceptisols are found in mountainous areas and are used for forestry, recreation, and watershed.
  • They occur in cool to very warm and humid to subhumid climates, from the arctic to the tropics.
  • They are found in Semi-arid and humid regions.
• Alfisols soil
  • They are moderately leached soils that have relatively high native fertility.
  • These soils have mainly formed under forest and have a subsurface horizon in which clays have accumulated.
  • They are primarily found in temperate humid and subhumid regions of the world.
