Question 1.
What does EC stand for in terms of water quality?
Show hintHide hint
Think about electrical conductivity in water.
Question 2.
Is an EC of 0.5 dS/m considered excellent, moderate, or unsuitable for irrigation?
Show hintHide hint
Refer to the classification of EC values.
3Question 3.
What does a high EC value indicate about water quality?
- Low salinity
- High salinity
- Moderate salinity
Show hintHide hint
Recall how EC relates to salinity.
4Question 4.

- True
- False
Show hintHide hint
Think about the classifications of EC values.
Question 5.
You have irrigation water with an EC of 4.0 dS/m. What strategies would you implement to ensure suitable conditions for crops?
Show hintHide hint
Think about ways to reduce overall salinity levels in irrigation.
Question 6.
A farmer notices significant leaf burn in crops irrigated with water having an EC of 3.5 dS/m. Explain the relationship between salinity and leaf burn, and suggest a management practice.
