Question

What process is mainly responsible for the formation of laterite soil, and why does this process make the soil generally poor in plant nutrients?

Accepted Answer

## Model Answer Laterite soil is formed mainly due to **intense leaching** caused by heavy rainfall in tropical and subtropical regions with alternating wet and dry seasons. During leaching, heavy rain washes away soluble nutrients and minerals from the upper layers of the soil. As a result, the soil becomes **acidic (pH < 6.0)** and is **generally deficient in plant nutrients**, making it infertile for most crops. *Source: Resources and Development, Laterite Soil* --- ## Explanation - The two key points examiners look for are: (1) **leaching** as the process, and (2) **nutrients being washed away**, leaving the soil nutrient-deficient and acidic. - Use the term "intense leaching" directly — it appears in the textbook. - Mentioning pH < 6.0 adds precision and shows textbook familiarity, which examiners appreciate. - Keep both points balanced since this is a 2-mark question (1 mark per point).
