Explanation:

Characteristics of Alluvial Soils

They are immature and have weak profiles due to their recent origin.

Most of the soil is Sandy and clayey soils are not uncommon.

Pebbly and gravelly soils are rare. Kankar (calcareous concretions) beds are present in some regions along the river terraces.

The soil is porous because of its loamy (equal proportion of sand and clay) nature.

Porosity and texture provide good drainage and other conditions favorable for agriculture.

These soils are constantly replenished by the recurrent floods.

Major characteristics of alluvial soil are:

1. It is formed by the deposition of the river load as it flows from its upper to its lower course.

2. It is light and porous, therefore easily tillable.

3. It is a fertile soil as it is rich in minerals, especially potash and lime.

4. It is suitable for the growth of a large variety of rabi and kharif crops.

5. Soils in the drier areas are more alkaline
