INDIAN GEOGRAPHY

Detailed explanation-1: -The Khadar is composed of newer alluvium and forms the flood plains along the river banks. They are sandy clays and loams, more dry and leached, less calcareous and carbonaceous. The banks are flooded almost every year and a new layer of alluvium is deposited with every flood.

Detailed explanation-2: -The Bhangar region has calcareous deposits, locally known as Kankar while the Khadar soil has fine silt and clay. The soil in Bhangar is coarser, whereas the Khadar soil is finer. Thus, Khadar is more fertile than Bhangar. And thanks to the fertile soil, there is intensive agriculture practised in the Khadar region.

Detailed explanation-3: -Khadar type of soil is present in northern plains. It contains new alluvium. This type of alluvium is used extensively for agriculture.

Detailed explanation-4: -Khadar soil is richer than Bangar as it gets renewed by new layers of soil each year during storm floods. Khadar soils also have lower concentrations of kankar nodules and a high concentration of finer particles hence it is also considered to be more fertile than Bangar soils.
