Question

The old alluvium on the slightly elevated terraces are known as_________
A. Bangar
B. Terai
C.Khadar
D. Bhabar

Answer 1

Hint: Alluvial soil is largely present in the Terai region. It has the highest rate of fertility is present in this soil. The alluvium is loose soil that is brought down by the rivers and gets deposited in its bed.

Complete answer: The Alluvial soil consists of boulder, clay, gravel, sand, silt and several other particles along with organic matter that makes the soil fertile. The old alluvium on the slightly elevated terraces are known as Bangar. Hence these soils are not much fertile.The Bangar soil lies beyond the floodplains. It has sandy and loamy content.These soils although are less prone to flooding, are not highly fertile as well.The Bangar area is subdivided into two types: Barani, Nahri and Chahi.
Barani: These are areas which are dependent on rainfall for agricultural purposes. These are low rain areas which practice dry farming.
Nahri : It is a land irrigated by canals.
Chahi is an area which is irrigated using tube wells and wells.
The Bangar soil contains a high amount of Kankar nodules. Bangar is found in the area between two rivers which is known as the doab region. In India it is peasant in the Ganga Yamuna Doab region.

Hence, Option A is the right answer.

Note: Khadar is the newer alluvial soil that is found in low lying flood areas and hence more fertile. The Bangar deposits are found in large areas of the Northern Plains. The deposits of alluvium are brought down by the rivers of the northern plains.
