Step 1: Understanding leaching process
Leaching is the process in which heavy rainfall washes away soluble nutrients and minerals from the soil, leaving behind less fertile soil.
Step 2: Identify soil type
- Laterite soil is formed under conditions of high temperature and heavy rainfall.
- Due to intense leaching, laterite soils are poor in nutrients like nitrogen, phosphorus, and potassium.
- They are rich in iron and aluminium, which gives them a reddish color.
Step 3: Conclusion
Hence, the soil formed due to leaching by heavy rainfall is Laterite soil.
The correct answer is option (C).
Release of iron from primary minerals and their dispersal as coatings on soil particles to impart brown to red colour to soil particles is called:
(A) Braunification
(B) Ferruginisation
(C) Rubification
(D) Laterisation
