  • It is Reddish to yellow in colour.
  • It is unsuitable for agriculture but crops such as coffee, rubber, cinchona, cashew, coconut, etc. are grown on this soil.
  • This soil is formed due to the weathering of laterite rocks caused by high temperatures and heavy rainfall with alternate dry and wet spells.
