Aerial Sprays for Android

11 things about Aerial Sprays

1. To make the most efficacious application to a field or orchard, aerial applicators select specific operational parameters (such as spray nozzle type, spray pressure, airspeed, etc…) that will result in spray droplet sizes that produce maximum on-target deposition of the applied product with minimal off-target movement.

2. The Aerial Application Technology team has developed a series of computer models that easily allow applicators to predict the resulting spray droplet size parameters using their selected operational parameters.

3. The spray nozzle models provide applicators with estimates of spray droplet size based on four input parameters that are set by the user.

4. The Aerial Application Technology team is a research group within the United States Department of Agriculture’s (USDA), Agricultural Research Service (ARS).

5. We are responsible for conducting and reporting research that supports the nation’s aerial applicators, who in turn, work with farmers and other producers to protect and supply the nation’s food and fiber crops.

6. Reference to any specific commercial products, process, or service by trade name, trademark, manufacturer, or otherwise, does not constitute or imply its endorsement, recommendation, or favoring by the United States Government or USDA-ARS.

7. o Droplet size (in µm) such that 10, 50, or 90% of the spray volume, respectively, is contained in spray droplet sizes of equal or less.

8. While the Aerial Application Technology team makes every effort to ensure that its databases are error-free, errors do occur.

9. o The size classification of the resulting spray based on an engineering standard (ASABE S572 ( ).

10. There are currently 19 nozzle models available for use (10 for nozzles for fixed-wing aircraft and 9 for nozzles used for helicopters).

11. These models have been available and widely used for a number of years as a series of downloadable spreadsheets.
