Khādir or Khadar and Bangar, Bāngur or Bhangar (Hindi language: खादर और बांगर, Urdu languageکهادر اور بانگر) are terms used in Hindi, Urdu, Punjabi and Sindhi in the Indo-Gangetic plains of North India and Pakistan to differentiate between two types of river plains and alluvial soils. Bangur and Khadir areas are commonly found in the doab regions. Some villages may have both Khadar and Bangar areas within their revenue boundaries. Bhangar soils are less fertile as they are above flood level whereas Khadar soils are more fertile as they are below the flood level. Bhanger is full of kankers (lime nodules) while khadar soil is composed of fine silt and clay. It is fertile land as it contains alluvial soil deposited by rivers. Khadir or Nali areas Khadir or Khadar (Hindi: खादर or खादिर), also called Nali or Naili, are low-lying areas that are floodplains of a river and which are usually relatively narrower compared to unflooded bangar area. Khadar areas are prone to flooding and sometimes include portions of former river-beds that became available for agriculture when a river changes course. It is moisture retentive and sticky when wet. Khadir soil consists of new alluvial soil relatively higher in new silt content from the river, gets replenished with each flooding cycle, and is often very fertile. The Khadir is also called Nali in the northern Haryana which is the fertile prairie tract between the Ghaggar river and the southern limits of the Saraswati channel depression that gets flooded during the rains. Sri Sri Ravi's Art of Living Foundation World Culture Festival, 2016 (11 March) was held on Yamuna's Khadir floodplains and National Green Tribunal (NGT) recommended a fine of INR 50 million, on Art of Living Foundation for damaging ecology on Yamuna's Khadar flood plains. Bangar areas and subtypes Bangar/Bangad/Bhangar (Hindi: बांगर) areas are beyond the floodplains, that lie more upland, and compared to Khadar it consists of older alluvial soil which is higher in sandy loam content. Bangar areas are less prone to flooding but are usually more sandy and less fertile as well. A Bangar area, can be further subdivided into the following based on the type of irrigation: Barani area are traditionally rain-fed areas. These are any low rain area where rain-fed dry farming is practiced. Bagar tract, the dry sandy tract of land on the border of Rajasthan state adjoining the states of Haryana and
