Detailed explanation-2: -Coastal alluvial soil is formed by the deposition of alluvium and sediments carried by rivers and seas over many years, which makes this soil fertile. It also contains sand, silt and clay in different proportions and is rich in organic minerals.

Detailed explanation-3: -The three chief characteristics of the Alluvial soil are as follows: This soil is very fertile in nature. Alluvial soil is mainly used for the production of vegetables. Various proportions of sand, silt, and clay in different amounts form the alluvial soil.

Detailed explanation-5: -2.2 Alluvial Soil Alluvial soil has the highest productivity with respect to other soils. It is present mostly along rivers and is carried by its streams during weathering of rocks.

Detailed explanation-6: -Alluvial soil is the most fertile soil, followed by black soil, red soil, laterite soil, and desert soil. Its fertility depends on its minerals and organic content.
