Explanation
All three clues point directly to Black Soil (Regur soil):
- "Extremely fine material" → clayey texture of black soil
- "Rich in soil nutrients" → calcium carbonate, magnesium, potash, lime
- "Ideal for growing cotton" → its alternate name is black cotton soil
Alluvial soil is ideal for wheat/sugarcane; Laterite is acidic and nutrient-deficient; Arid soil is sandy. Eliminate these confidently.
