Why is alluvial soil called fertile soil?

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.

From space, the contrast between the Nile’s lush green river banks and the barren desert through which it flows is obvious. For millennia, much of Egypt’s food has been cultivated in the Nile delta region.

Why is the Nile River rich in nutrients?

The soil of the Nile River delta between El Qâhira (Cairo) and the Mediterranean Sea is rich in nutrients, due to the large silt deposits the Nile leaves behind as it flows into the sea. The banks of the Nile all along its vast length contain rich soil as well, thanks to annual flooding that deposits silt.
