Explanation:
Alluvial Soil | Black Soil |
---|---|
1. Originated from the transported alluvium brought by the rivers. | Originated from the solidification of basic lava, spread over large areas of Deccan Plateau during volcanic activity. |
2. Rich in potash and humus but deficient in phosphorus and nitrogen. | Rich in lime, alumina, iron, potash, magnesium carbonate and calcium and deficient in potash, nitrogen and humus. |
Explanation:
Removal or destruction of top soil by the agents like winds and running water is called soil erosion.
1. Afforestation : The best way to prevent soil erosion is to increase area under forests.
2. Constructing dams and barrages : Soil erosion by flood can be checked by constructing dams or barrages over the rivers. This checks the speed of water thereby saving soil from erosion.
Explanation:
(i) Red Soil is formed in situ by weathering of the ancient crystalline and metamorphic rocks.
