Correct Answer : It should be used with appropriate water management practices
Explanation : If the salt concentration is less than 0.5 g/L, then there is no salinization risk and no restriction on the use of irrigation water. If the concentration is more than 2 g/L, there is high risk and is not generally advised for use. If the concentration is in between there is slight to moderate risk and it should be used with appropriate water management practices.
