Alluvial soil is fertile because it contains alluvium. The alluvium is a material deposited by the rivers along its course in the lower regions, forming extensive deltas and flood plains.
The alluvium is made up of silt, sand, clay, and gravel. Alluvial soil is also rich in phosphoric acid, potash, and lime. The soil also has good water-absorbing and water retention capacity.
The rivers constantly replenish the soils. Almost all the significant crops can grow in alluvial soil like wheat, rice, sugarcane, etc.
