If chemigation equipment is functioning properly, what is the expected outcome?

• A. Provides thorough crop coverage
• B. Provides uneven coverage
• C. Drifts off target
• D. Requires more water

Answer: (A)

When chemigation equipment operates correctly, the pesticide or fertilizer is carried evenly with the irrigation water, providing thorough crop coverage across the field. This comes from proper calibration of the injection rate, appropriate pump pressure, and correct nozzle type and spacing, which together ensure the solution reaches the entire canopy or soil surface rather than concentrating in spots. If any part of the system is out of calibration or malfunctioning, you’d typically see uneven coverage, drift off target, or the need to use more water to try to achieve the same level of application.
