Which of the following statements with reference to saline soil in India is/are correct? 1. They are rich in nitrogen. 2. They occur in arid and semi-arid regions, and in waterlogged and swampy areas. Select the answer using the code given below :

Saline soils in India are characterised by high content of soluble salts like sodium, potassium and magnesium, but they are POOR in nitrogen and calcium — hence statement 1 is incorrect. They typically occur in arid and semi-arid regions due to high evaporation rates concentrating salts at the surface, and also in waterlogged and swampy areas like coastal plains (e.g., Rann of Kutch, Sundarbans) where poor drainage leads to salt accumulation. Statement 2 is correct.
