Saline and Alkaline Soils:
- The development of these soils has happened in those areas where dry climate is found
and there is a lack of proper drainage. - In this situation salts of sodium, calcium and magnesium are deposited on the upper
layer of the soil by the capillary action. Therefore, the quantity of salt (salinity) in these
soils increases too much. - These soils are also formed when saline water spreads on the land at the time of high tide
in coastal areas. - These soils are deficient in nitrogen and lime.
- These are intra-zonal soils.
- These soils are found in southern Punjab, Sountern Haryana, Western Rajasthan, the
coast of Kerala, the Sunderbans etc. - In coastal areas the coconut trees are found in plenty in these soils.
