Answer:

c . Deltaic alluvial soil

Answer 2

The type of alluvial soil that is less porous, coarse, loamy, heavy due to the high content of fine particulate mud and found in the riverine parts of north-south India is- c. Deltaic alluvial soil.

Characteristics of deltaic alluvial soil are-

• The deltaic alluvial soils are found on or near the deltas of rivers. These soils are found in north-south India on the deltas of Ganga-Brahmaputra and Mahanadi-Godavari rivers.
• On their journey from mountains, the rivers brought high content of fine particulate mud and sediments with them. Hence, the soil is fertile and is rich in minerals.
• The soil contains different size particles such as sand, silt and clay. Hence, deltaic alluvial soil is loamy in texture.
• The soil is less porous due to the presence of clay and coarse due to the presence of sand.
• The deltaic alluvial soils are formed every year as they are present in the flood plain regions where new soils are annually deposited by the rivers.
