Explanation:
Detailed explanation-1: -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-2: -Alluvial soil is the most fertile soil because it has a loamy texture (contain sand, clay and slit) and is rich in humus, contains organic nutrients. A granular material composed of finely divided rock and mineral particles are called sand. Sand with clay and slit helps to increase fertility of alluvial soil.
