What is the primary goal of maintaining a drip irrigation system?
B
Prevent clogging and ensure uniform water application
D
Increase soil temperature
Analysis & Theory
Proper maintenance ensures consistent water delivery and prevents system failures like clogging.
How often should the drip system be flushed to remove sediment and blockages?
C
After every irrigation cycle
Analysis & Theory
Regular flushing, typically every 7–10 days, prevents accumulation of debris in the laterals and emitters.
Which component must be checked and cleaned frequently to prevent emitter blockage?
Analysis & Theory
Filters remove particles that can clog emitters; keeping them clean is crucial.
Which symptom indicates emitter clogging in the field?
B
Pooled water near one plant
Analysis & Theory
Uneven plant growth often results from blocked emitters or poor water distribution.
Which of the following is a common cause of emitter clogging?
C
Algae and mineral deposits
Analysis & Theory
Algae, biological growth, and mineral buildup are common causes of clogging in emitters.
What maintenance activity helps prevent algae growth in the system?
D
Using untreated surface water
Analysis & Theory
Algae grow in sunlight; using shaded or covered tanks reduces their development.
Why is acid flushing done periodically in drip systems?
B
To remove chemical deposits
D
To dissolve soil particles
Analysis & Theory
Acid flushing dissolves calcium and magnesium deposits that can clog emitters.
Which tool is commonly used to check pressure at different points in the system?
Analysis & Theory
Pressure gauges help monitor system pressure and detect drops due to clogging or leaks.
How should lateral pipes be maintained during off-season?
C
Flush, dry and store in shade
Analysis & Theory
Cleaning and storing laterals in the shade extends their life and prevents damage from UV rays.
Which of the following is a good maintenance practice during system operation?
A
Over-irrigation to clean emitters
B
Frequent inspection for leaks or breaks
D
Increasing fertilizer dosage
Analysis & Theory
Regular inspection helps identify and fix leaks, damaged pipes, or faulty emitters promptly.
