Khadar refers to a type of fertile alluvial soil found in river valleys, particularly in regions of India and Pakistan. This soil is rich in nutrients and is ideal for agriculture, supporting the growth of various crops. It is typically deposited by rivers during floods, making it highly productive for farming. The term "Khadar" is often contrasted with Bhangar, which is older, less fertile soil found at higher elevations away from riverbanks. While Khadar is more suitable for crops like rice and wheat, Bhangar is generally used for growing less demanding plants.
