Answer 2

Answer:

The Banker soil or the old alluvial soil is having the highest concentration of the banker nodules.

• The banker nodules are made up of calcium carbonates which mostly found in the Indo Gangetic plains. These nodules hinder the fertility of the soils.
• It is present in the form of sheets or discontinuous lines of the nodules in the stereo graphic regions of the soil.
