40. Quality of Irrigation Water

Try these first

1. 1.

   What is Electrical Conductivity (EC)?

   Hint

   Think about how salt in water affects electrical flow.

2. 2.

   What do high sodium levels in irrigation water lead to?

   Hint

   Consider how sodium affects soil structure.

3. 3.

   What does Electrical Conductivity (EC) measure?

   • Water temperature
   • Water salinity
   • Water pH

   Hint

   It’s related to the dissolved salts in the water.

4. 4.

   True or False: A SAR greater than 18 is suitable for all crops.

   • True
   • False

   Hint

   Think about the impact of sodium on soil health.

5. 5.

   You are tasked with monitoring irrigation water quality for a farmer. The EC values fluctuate from 0.5 to 3.5 dS/m. Assess the risks involved and recommend management practices.

   Hint

   Consider how you would advise the farmer and what practical steps could be taken.

6. 6.

   Analyze a case where crop yields have decreased due to high salinity levels. What tests would you implement to assess water quality, and what solutions could you suggest?

   Hint

   Think about specific tests and practices relevant to water quality.
