The purpose of this Standard is to provide a method to evaluate application accuracy of granular materials applied using variable-rate application systems including spinner-disc and pneumatic broadcast applicator or similar equipment that distribute fertilizers. Specifically, this standard will facilitate the collection and reporting of map-based application accuracy of both single and multiple granular products.

Testing of equipment commonly used to support site-specific management, machinery guidance, and other precision agriculture practices forms the basic scope of this Standard.
