Khadir or Khadar are the low-lying areas, also called Nali or Naili. Khadar areas are vulnerable to floods and often have parts of former river beds that were made available for cultivation when the course of a river changes. It is sticky and retentive with moisture when wet.
Khadir formation is composed of fresh alluvial soil that is comparatively higher in the river's new silt content, is topped up with every flood cycle, as well as being very fertile.
In northern Haryana, that is the abundant prairie tract between both the Ghaggar river and the southern limits of the depression of the Saraswati canal, the Khadir is also called Nali. According to the khadar map, these regions get flooded during the rains.
