Preview Questions Irrigation Specialist | Role Specific Skill

Question 1: What is the purpose of calculating the crop coefficient (Kc) in irrigation management?

Which action should you take?

Choose only one option

To estimate crop water demand based on growth stage and weather conditions

To assess the impact of fertilizers on crop growth

To determine the volume of water required to prevent soil erosion

To reduce the frequency of irrigation cycles

Question 2: What is the primary advantage of using sub-surface drip irrigation (SDI) over surface drip systems?

Which action should you take?

Choose only one option

Higher water application rates

Reduced evaporation losses and better water retention

Reduced risk of clogging from debris

Easier to install and less expensive

Question 3: What is the role of a backflow preventer in a drip irrigation system?

Which action should you take?

Choose only one option

To control the emitter discharge rate

To filter out debris from the water

To prevent contaminants from entering the water supply

To reduce water pressure in the system

Question 4: What is the main challenge of maintaining an irrigation system in a region with hard water?

Which action should you take?

Choose only one option

Increased risk of emitter clogging due to mineral buildup

Higher energy costs due to low water pressure

Frequent system leaks due to corrosion

Inconsistent irrigation coverage due to uneven water quality

Question 5: What is the ideal way to manage water runoff in irrigation systems to avoid environmental damage?

Which action should you take?

Choose only one option

By using contour farming and implementing water catchment systems

By increasing the irrigation flow rate to remove excess water

By installing large drainage channels that redirect water

By applying irrigation during rain to reduce the runoff

Question 6: What is the best method for addressing irrigation runoff in agricultural fields?

Which action should you take?

Choose only one option

Use contour farming and install drainage systems

Increase irrigation frequency to compensate for runoff

Use a higher water pressure to overcome runoff

Apply irrigation only during rainfall events
