Question

Laterisation involves the following:

• A. Removal of Fe and Al complexed with humus from upper to lower horizon
• B. Removal of silica from soil
• C. Removal of silica and accumulation of sesquioxides in soil
• D. ccumulation of sesquioxides in soil

Hint:

Laterite soils are typically rich in iron and aluminium oxides due to intense leaching of silica.

Answer 1

The Correct Option is C

Laterisation is the process where silica is leached from the soil profile while Fe and Al oxides accumulate, leading to sesquioxides dominance in the soil.
