Explanation:

Which is the most fertile part of the river of Northern plain. 

Bhabar, bhangar, khadar and terai are the geological divisions of alluvial soils.

Bhabar: It is found in the foothills of Shivaliks. It is 8 to 16 kms wide. It comprises of pebble studded rocks and hence no rivers. It is not suitable for agriculture.

Bhangar: It covers large parts of northern plains. It is composed of old alluvial soil. It contains calcareous deposits locally known as 'Kankar'. Soil is not very fertile.

Khadar: Ii is also present in northern plains like that of Bhangar. It contains new alluvium. Used extensively for agriculture.

Terai: It is composed of comparatively finer alluvium and is covered by forests. It has underground streams and makes the area marshy. Suitable for agriculture.

Answer 2

The Bhabar Plains

• The Bhabar plains is located to the south of Shiwalik from Jammu to Assam.
• The breadth or width of bhabar plains is more in the western region as compared to the eastern region.
• The bhabar tract comprises of gravel and un-assorted sediment deposits.
• This sediment present in soil is deposited by rivers descending from the Himalayan mountains.
• This region is not good for cultivation.
• The area is popular with big trees with large roots.

The Tarai tract

• The Tarai tract is situated south to the Bhabar tract.
• The track is a marshy tract with malarial climate.
• The width of Tarai tract is more in the eastern region.
• This Tarai tract receives high rainfall and has excessive humidity, due thick forest and rich flora and fauna.
• Recently the Tarai tract in Haryana, Punjab, Uttarakhand, and Uttar Pradesh has been cleared for cultivation because it is rich in humus and organic matter.
• It is suitable for the cultivation of Wheat, rice, maize, sugarcane etc.

The Bhangar Plains

• These are older alluvial plain which represents upland alluvial tract.
• These areas are well-drained and make it suitable for cultivation.
• This area lies quiet above the flood limits of the neighbouring rivers.
• The soil is rich in humus and it gives a high yield due to rich amount of minerals and humus in the soil.
• It comprises of calcium carbonate nodules called ‘Kankars’ which are impure in nature.

The Khadar Plains

• The new plains formed due to alluvial deposit along the course of the river.
• Enriched and formed by fresh deposits of silt every year.
• The Khadar land silt comprises of silt, mud, clay, and sand.
• The Khadar lands are suitable for the cultivation of sugarcane, rice, wheat, maize and oilseeds.
