What does GPA stand for in the context of aerial application?

In the context of aerial application, GPA stands for Gallons per Acre. This term is a critical aspect of precision agriculture and aerial application practices, as it refers to the amount of liquid pesticide, herbicide, or fertilizer that is applied over one acre of land. Understanding GPA is essential for achieving effective chemical coverage while minimizing waste and environmental impact.

Using the correct GPA ensures that the application not only meets agricultural needs but also adheres to regulatory requirements and best management practices. Applying too little may result in ineffective treatment, while applying too much can lead to runoff and damage to surrounding ecosystems. Therefore, accurately calculating and implementing the appropriate GPA is fundamental in the operation of aerial applicators. This metric is a standard reference in the industry, making it crucial for aerial applicators to be familiar with and proficient in its application.
