Which of the statement about the Saline soils of India is incorrect?

Naturally, these soils are found in areas of dry climate and poor drainage or in waterlogged swampy areas.

Excessive irrigation in dry climatic conditions of North-West India is making the soils saline in that region.

These soils are poor in Sodium and Potassium.

Gypsum is added to lower the salinity of such soils.

Explanation:

These soils are rich in salts like Sodium , Potassium, Magnesium etc. They lack Nitrogen instead.
Gypsum lowers the ph of the soils and hence reduces salinity to some extent.

"These soils are poor in Sodium and Potassium" is incorrect. Saline soils typically contain high levels of soluble salts, including sodium and potassium. These salts are one of the key characteristics of saline soils and contribute to their salinity.
