Khadar and Bhangar are soil types of which of the following?

Correct option is B

The correct answer is (B) Alluvial

Explanation:

• Khadar and Bhangar are the two primary classifications of Alluvial soil based on their age and location in the floodplains.

• Bhangar is the older alluvial soil found in the higher reaches of the river terraces, away from the floodplains. It often contains kankar (calcareous deposits) and is less fertile.

• Khadar is the newer/younger alluvial soil found in the low-lying areas of the river valley, which are flooded almost every year.

• Khadar is more fertile than Bhangar because it is replenished with fresh silt and fine clay every year during floods.

• Alluvial soil is the most widespread and productive soil type in India, covering the entire Northern Plains and coastal strips.

Information Booster:

• Alluvial soils are rich in Potash and Lime but generally poor in Nitrogen and Phosphorus.

• They are highly suitable for the cultivation of Wheat, Rice, Sugarcane, and Pulses, supporting the majority of India's agricultural population.

Additional Knowledge:Black Soil (Option A)

• Also known as Regur soil, it is formed from the weathering of volcanic (basaltic) rocks. It is famous for its water-retaining capacity and is ideal for growing cotton.

Red Soil (Option C)

• This soil develops on crystalline igneous rocks and appears red due to the high diffusion of iron. It is found mainly in low-rainfall areas of the eastern and southern parts of the Deccan Plateau.

Laterite Soil (Option D)

• Formed in areas with high temperatures and heavy rainfall through the process of leaching. It is useful for growing cashew nuts, tea, and coffee after being treated with fertilizers.
