Where should the speed of a granular applicator be checked during calibration?

Calibration of a granular applicator is crucial for ensuring the correct application rate of pesticides or fertilizers. The speed of the applicator should be checked in the field where they will be applied because this environment reflects the actual conditions under which the applicator will operate. Factors such as terrain, soil type, and any obstacles present in the field can significantly affect the performance and calibration of the applicator.

By checking the speed in the field, you can ensure that the equipment is functioning correctly for the specific conditions it will encounter during use, allowing for accurate application rates that align with the intended treatment plan. This contextual calibration helps prevent errors that could lead to over-application or under-application of materials, which can have implications for crop health, pest management, and environmental safety.
