When should calibration of the spraying system be performed?

Calibration of the spraying system is crucial for ensuring the effectiveness and safety of aerial applications. Performing calibration before every application helps to ensure that the equipment is operating correctly and applying the correct rates of pesticides or fertilizers. This regular check prevents over-application or under-application, both of which can have negative consequences on crop health and the environment.

Calibration after significant repairs is also essential. Any maintenance or replacements in the spraying system can alter the performance, so recalibrating ensures that any changes are accounted for and that the system is delivering inputs as intended.

Conducting calibration only once a year does not account for the variability in environmental conditions, equipment wear and tear, and potential system changes throughout the growing season. Regular checks and calibrations help maintain the highest standards of application precision and efficacy. Therefore, all the suggested times for calibration—before every application, after significant repairs, and even the yearly check—are important parts of an effective aerial spraying program.
