  • They have more salts, largely because of dry climate and poor drainage.
  • They occur in arid and semi-arid regions, and in waterlogged and swampy areas. Their structure ranges from sandy to loamy.
  • They lack in nitrogen and calcium. Saline soils are more widespread in western Gujarat, deltas of the eastern coast and in Sundarban areas of West Bengal.
