Red and Yellow Soils

The reddish – yellow colour is due to the presence of iron oxide. These soils are formed where the rainfall is low and there is a little leaching lesser than that in the laterite soils. Red soils are as such usually developed on old crystalline and metamorphic rocks. These are sandier and comparatively less clayey.

These soils cannot retain moisture for a longtime. Use of manures increases their fertility. The soils are deficient in phosphorus, nitrogen and humus. They are acidic in nature and have iron, aluminium and lime in sufficient quantities. If the soils are fine grained, they are fertile. These are porous soils. They are not fertile on higher dry lands.

These soils are found in three regions :

  1. Central – From Bundelkhand, Baghelkhand to the south, from Orissa, eastern A.P and T.N., these soils occupy large areas.
  2. Western – The eastern and south – eastern narrow belt to the eastern side of the Aravalis.
  3. Eastern – Parts of Meghalaya, Nagaland, Manipur, Mizoram, etc.

If the soils are not fertile, millets are grown. Where they are deep, deep red and fertile, the main crops grown are wheat, cotton, potato, rough grains and others.
