In a laterite soil profile, which of the following elements is present in an excessive amount?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Iron.
In a laterite soil profile, iron is present in an excessive amount. Laterite soils are rich in iron and aluminum oxides, giving them a characteristic reddish or yellowish color due to the high iron content. These soils form in hot, humid tropical regions through intense weathering and leaching of silica and other soluble materials, leaving behind iron and aluminum compounds. The abundance of iron oxide makes laterite soils hard and compact when dried. These soils are often acidic and low in fertility but are important sources of iron ore and are used in construction and road-building materials in many tropical countries.
