UPSC CAPF AC 2021 Paper

In arid soils, the salt content is so high that common salt is obtained by evaporating the saline water in some areas. The regions of Rajasthan, Punjab and Haryana are arid and semi-arid. The sand here is blown from the Indus basin and the coast by the prevailing south-west monsoon winds.
Due to the dry climate, high temperature and accelerated evaporation, they lack moisture and humus. Nitrogen is insufficient and the phosphate content is normal.In large areas, only the drought resistant and salt tolerant crops such as barley, cotton, millets, maize and pulses are grown.
