Solution

  • Red soil requires irrigation because it is made under warm conditions. It is seen mainly in low rainfall areas.
Red soil is red because of Ferric oxide.
The lower layer is reddish yellow or yellow.
  • Afforestation prevents soil from getting eroded by several ways.
Afforestation will help in binding the soil to the ground on the slope layers.
It will also help in reducing the impact of washing away of the soil due to heavy rainfall.
  • Laterite soil is red in color because it is rich in Iron and Aluminium.
It is developed due to leaching away of silica on the top of the crust of earth leaving Iron and Aluminium behind.
