Key Points
- Aridisols soil
- 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.
- Vertisols
- They are clayey soils that have deep, wide cracks for some time during the year.
- They shrink as they dry and swell as they become moist.
- The natural vegetation is predominantly grass, savanna, open forest, or desert shrub.
- They are found in Humid and super-humid regions.
