Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Excessive use of chemical fertiliser's causes soil deterioration through the decrease in natural bacterial population and destruction of crumb structure. The salt content of the soil is also bound to increase with continuous use of fertilisers. Excessive use of alkaline fertilisers like sodium nitrate, basic slag, etc. may develop alkalinity in soil.
