Q1. [2] deep thorough-understanding
Despite being generally acidic and deficient in nutrients, laterite soils in Karnataka, Kerala and Tamil Nadu are successfully used for tea and coffee cultivation. What does this tell us about the relationship between soil quality and agricultural productivity?

Model Answer
Laterite soils are generally acidic (pH < 6.0) and deficient in plant nutrients, making them unsuitable for many crops. However, with appropriate soil conservation techniques, they can be used productively. This shows that soil quality alone does not determine agricultural productivity — human intervention, crop selection suited to local soil conditions, and conservation methods can overcome natural soil deficiencies.

Explanation
- The question tests whether you can draw a conclusion from the given example, not just describe laterite soil.
- Key point from the passage: "After adopting appropriate soil conservation techniques… this soil is very useful for growing tea and coffee." Quote or paraphrase this.
- Examiners want: (1) acknowledgment of the soil's limitations, and (2) the inference that human effort/crop suitability bridges the gap between poor soil and productive agriculture.
- Avoid writing a general essay on soils — two tight points are enough for 2 marks.
