Detailed explanation-1: -Old and new alluvial respectively are called bangar and khadar because of bangar formed by old alluvial and new khadar formed by new alluvial in india. It is also known as the Northern Plain of India.

Detailed explanation-2: -Old alluvial soil is known as Bhangar and is full of Kankars (lime nodules). The Bhangar is the older alluvium along the river beds forming terraces higher than the floodplain. Bhangar contains fossils of animals like rhinoceros, hippopotamus, elephants, etc. This type of soil is found in mountainous regions.

Detailed explanation-3: -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.

Detailed explanation-4: -Bangar is a less fertile soil and it is an old alluvial soil. Bangar areas are less prone to flooding but are usually more sandy and less fertile as well. They consist of a higher concentration of kankar nodules. They are slightly elevated terraces. That’s why these areas are less fertile.

Detailed explanation-5: -Old alluvial soil is found at the top of the mountain whereas new soil is found near bank of rivers brought by rivers only. old soil is less fertile while new is more fertile. Old soil is dark yellowish in colour and new is yellowish in colour. They are also known as khadar and bhangar later being the old Soil.
