What is the effect on saline-alkaline soil when it is irrigated with water?

Show Answers

The pH lowers while electrical conductivity risesBoth pH and electrical conductivity riseThe pH rises and electrical conductivity fallsNo change occurs

Explanation

When saline-alkaline soil is watered, the pH level increases due to the dilution of salts, while the electrical conductivity decreases as soluble salts are leached out. Therefore, pH goes up and EC goes down.
