Alluvial soil is found in India, in the northern part of India, basically in the foothills of the Himalayas. Alluvial soil is loamy, fertile, and potash-rich soil.

Here are the characteristics of alluvial soil:

Water retention capacity and loamy soil: The alluvial soil has a high water retention capacity to absorb water.

Good for agricultural use and very fertile in nature: Most of the northern area depends on agriculture due to the good fertile soil available in this area.

Formed by the deposition of rivers and wind: From the Himalayas, the hill particles come and deposit in the foothills due to deposition and weathering.

Composition: Alluvial soil is generally in the form of fine particles of sand, silt, etc, with a high quantity of potash.

Subtypes:

Bhabar: Coarse sand and gravel deposited by rivers. Generally, big particles as compared to other particles. Found in the foothills of the Himalayas.
Terai: Near the foothills and lower than Bhabar with finer alluvial deposits.
Bhangar: The older alluvial soil due to the deposition of rivers; it is less fertile as compared to Khadar soil.
Khadar: The newer and more fertile soil, changes over time, and is found in floodplains of rivers and nearby the delta region.
