Question

What kind of soil is found in the northern plains?

Answer 1

Hint: This type of soil has very rich and intense deposits in the northern plains. It contains lime, potash, and phosphorus. This type of soil is very fertile. And many kinds of crops can be cultivated in this soil. This soil deposit consists of slit, clay, and sand.

Complete answer:
Northern plains are also known as Indo-Gangetic plains. The soil found in the northern plains is alluvial soil which was deposited millions of years ago. The total area of the northern plain implies seven lakh square kilometers. The Northern plain is about $2400$ km long. The northern plain is divided into three sections:
1. Punjab plains
2. It is in the western part. It is formed by the Indus River. A Major portion of Punjab plain is in Pakistan.
Ganga plains
1. It is formed by the Ganga River. The states such as Haryana, Delhi, UP, Bihar, and West Bengal are situated in the Ganga plains.
Brahmaputra plains
1. It is in the eastern part. It is in the state of Assam.
Here we can divide the northern plain into 4 parts as follows:
A. Bhabar
All streams disappear in this region. It is formed when the river deposits pebbles in a narrow belt.
B. Terai
It is situated in the south of bhabar belt. Here the streams will reappear and make a wet, swampy region.
C. Bhangra
It is the largest part of the northern plain and has the oldest alluvial soil. They look like terraces. It has calcareous deposits.
D. Khadar
These regions are made by younger alluvium (Khadar). This soil is renewed every year and is fertile soil.
The northern plains have intense deposits of alluvial soil. Alluvial soil contains amounts of lime, potash, and phosphorus. Alluvial soil helps in the growth of crops such as paddy, sugarcane, wheat, rice, maize, and other pulses. Alluvial soils are the deposits or materials from rivers. These deposits consist of silt, sand, clay, and organic matter. Alluvial soil is very fertile soil.

Note: Alluvial deposits are most extensive in the lower part of the river forming floodplains and deltas. Alluvial soil contains most of the world’s supply of tin ore, gold, platinum, and gemstones. In the Khadar region of the northern plain, the soil changes every year.
