Question

Why red soil requires irrigation

Answer 1

Red soils are aluminous and siliceous with quartz present as free sand. However, it is highly rich in other minerals like potassium. The top layers of the red soils are porous and sandy and the lower layers are fertile.

The red soils are very loamy and so, unlike the black soils, they cannot retain water. The water seeps down through the porous soils and so, they do not receive enough water for retention as the water tends to run-off.

Therefore, proper methods of using fertilizers and specific irrigation techniques are used so that the fertility of the red soils are increased. So, there will be a good quality yield of crops like cotton, pulses, rice, wheat, millets, oil-seeds, tobacco, potatoes, and many fruits.

Answer 2

Answer

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 thus it cannot retain water.
