Which of the following statements regarding laterite soils of India are correct? 1. They are generally red in colour. 2. They are rich in nitrogen and potash. 3. They are well-developed in Rajasthan and UP. 4. Tapioca and cashew nuts grow well on these soils. Select the correct answer using the codes given below.

Correct Answer: C) 1 and 4 Let's analyse each statement about Indian laterite soils: Statement 1: They are generally red in colour. Correct. Laterite soils are rich in iron and aluminium oxides, which give them their characteristic red to reddish-brown colour. Statement 2: They are rich in nitrogen and potash. Incorrect. Laterite soils are heavily leached and are deficient in nitrogen, phosphorus, potash, lime and magnesia; humus content is also low. They are generally low in fertility. Statement 3: They are well-developed in Rajasthan and UP. Incorrect. Laterite soils develop in regions of high temperature and heavy seasonal rainfall — chiefly the Western Ghats (Karnataka, Kerala, Maharashtra, Goa), Eastern Ghats (Odisha), Chota Nagpur Plateau, and parts of Assam and Meghalaya. Rajasthan has arid/desert soils and most of UP has alluvial soils. Statement 4: Tapioca and cashew nuts grow well on these soils. Correct. Despite low fertility, laterite soils (especially with fertilisers) support plantation crops such as tea, coffee, rubber, cashew nuts and tapioca. Therefore, only statements 1 and 4 are correct — option C.
