What is a concern when flying too low during a granule application?

When flying too low during a granule application, one primary concern is that the granules are still moving horizontally at lower heights. At reduced altitudes, the granules do not have adequate time to settle properly on the target area, which can result in an uneven application. The dynamics of air pressure and wind can also lead to increased drag on the granules, affecting their distribution and increasing the likelihood of them being blown away before they make contact with the intended surface. Therefore, understanding the physics of how granules behave at different altitudes is crucial for achieving an effective and uniform application.

Other considerations, such as the scattering of granules, potential disturbances to local wildlife, and effectiveness of granules, are important but do not directly address the impact that altitude has on the horizontal movement of the granules during application.
