• It is characterized by its fertility and is ideal for agriculture.
• Found in the flood plains of rivers, it is renewed during each flood cycle.
• This soil is typically more clayey and has a higher moisture retention capacity.
• Crops such as rice, wheat, and sugarcane are commonly grown in areas with Khadar soil.
• Examples of regions with Khadar soil include the Indo-Gangetic plains and the Brahmaputra valley.

 Additional Information

• Old alluvium
  • Also known as Bhangar, it is found at a higher level compared to Khadar.
  • It is less fertile due to its older formation and higher content of calcareous deposits (Kankar).
• Old Red soil
  • These soils are rich in iron oxide, giving them a distinct red color.
  • Commonly found in the Deccan Plateau and parts of southern India.
• New Red soil
  • Similar to old red soil but recently formed and often found in areas of recent volcanic activity.
  • These soils are also rich in iron oxide and are found in the tropical and subtropical regions.
