Question 1: What should be done if a drip irrigation system has pressure fluctuations in specific zones?

Which action should you take?

Choose only one option

Decrease the emitter size to balance pressure

Inspect for clogs, leaks, or damaged emitters in the affected zones

Ignore the fluctuations as they are normal in certain systems

Increase the flow rate to compensate for low pressure

Question 2: When designing a fertigation system, which of the following is the most critical parameter to control?

Which action should you take?

Choose only one option

The flow rate and pressure of the fertigation injectors

The type of fertilizer used

The nutrient concentration in the water

The frequency of fertigation cycles

Question 3: What is the recommended method for dealing with salinity build-up in a drip irrigation system?

Which action should you take?

Choose only one option

Applying more water than usual to flush the salts away

Increasing emitter flow to dilute salts

Using acidic solutions to dissolve the salts

Flushing the system with fresh water to leach out salts

Question 4: What is the primary benefit of using a drip irrigation system over traditional sprinkler irrigation?

Which action should you take?

Choose only one option

Less frequent maintenance required

Lower installation costs

Increased water efficiency and targeted delivery to roots

Higher water distribution uniformity

Question 5: How do you determine the proper pump size when designing an irrigation system?

Which action should you take?

Choose only one option

Based on the water storage capacity of the reservoir

Based on the diameter of the irrigation pipes

Based on the total pressure head and flow rate required

Based on the available power supply

Question 6: How should filters be maintained in a drip irrigation system to prevent clogging?

Which action should you take?

Choose only one option

Use chemical treatments to disinfect them

Only clean them when the system stops functioning

Clean them regularly and replace when worn out
