What is the primary concern when granules are applied from too low an altitude?

The primary concern when granules are applied from too low an altitude is increased drift. When granules are released from a low height during application, the granules may have less time to fall to the ground and can become influenced by environmental factors such as wind. This can result in the granules being carried away from the intended target area, leading to off-target application and potential environmental contamination.

Maintaining an appropriate altitude allows the granules to settle effectively and minimizes the impact of wind disturbances, ensuring more precise application. Proper altitude helps achieve better control of the application process, reducing the risk of drift and enhancing the overall effectiveness of the treatment. This understanding is crucial for aerial applicators who aim to optimize their operations while adhering to safety and environmental regulations.
