6. Arid-Desert soils

  • The desert soils consist of sand (90 - 95%) and clay (5 - 10%).
  • They are usually poor in organic matter.
  • Some desert soils are alkaline with varying degree of soluble salts like Calcium carbonate.
  • Calcium content increases downwards with the subsoil having ten times more Calcium.
  • The Phosphate content of these soils is as high as in normal alluvial soils.
  • Nitrogen is originally low but some of it is available in the form of Nitrates.
  • Phosphates and Nitrates make these soils fertile wherever moisture is available.
  • There is a possibility of reclaiming these soils if proper irrigation facilities are available.
