4.6 Saline and Alkaline Soils
In the drier parts of Bihar, Up Haryana, Punjab, Rajasthan and Maharashtra, are the salt –
impregnated or alkaline soils. Known by different names : Reh, kallar, USAR, etc. Some of
the salts are transported in solution by the rivers and canals, which percolates in the sub –
soils of the plains. The accumulation of salts makes the soil infertile and renders it unfit for
agriculture.
