Question

Explain the main features of alluvial soil.

Hint:

Alluvial soil is the most fertile and productive soil for agriculture. It is found in areas where rivers deposit nutrient-rich materials during floods.

Answer 1

Alluvial soil is a type of soil that is found in riverbeds, floodplains, and coastal areas, formed by the deposition of sediments carried by rivers. The main features of alluvial soil are: - Fertility: Alluvial soil is rich in minerals like calcium, magnesium, and potassium, making it highly fertile and suitable for agricultural activities. - Texture: The texture of alluvial soil can vary from sandy to clayey, depending on the size of the particles. It is generally loose and porous, which allows good air circulation and root growth. - Water Retention: This soil has excellent water retention capacity, making it ideal for crops like rice and wheat that require sufficient moisture. - Presence of Organic Matter: Alluvial soil is rich in organic matter due to the decomposition of plants and other organisms.
