Select the correct answer using the codes given below.
Detailed Explanation:
✅ Statement 1 – Correct: Laterite soils are characterized by their distinctive rusty-red colour due to high iron oxide content formed through leaching in tropical conditions.
❌ Statement 2 – Incorrect: Laterite soils are deficient in nitrogen, potash, potassium, phosphorus, and lime, though rich in iron and aluminium oxides; humus content is also very low.
❌ Statement 3 – Incorrect: Laterite soils are well-developed in high rainfall areas of Western Ghats, Eastern Ghats (Karnataka, Kerala, Tamil Nadu, Maharashtra), Odisha, Assam, and Meghalaya — not in semi-arid Rajasthan or UP.
✅ Statement 4 – Correct: Despite low fertility, tapioca, cashew nuts, tea, coffee, and rubber grow well on laterite soils with adequate fertilization and irrigation.
