Entisol
As entisol be designated according to the USDA Soil Taxonomy very young, shallow soils with no or little noticeable leveling, but variable pH . All soils that cannot be assigned to one of the other soil types are entisols. Due to their young age, they have almost no profile. Entisols are found in both tropical and temperate latitudes and are particularly common in the Sahara desert and the Middle East .
They also form on mountain slopes, where newly formed soil is severely eroded and the soil thickness therefore only increases slowly. Fine-grain loess deposits also lead to the formation of de-isols. They can definitely be used for agriculture .
The total area covered by this type of soil is about 21.1 million square kilometers, or about 16 percent of the ice-free land.
