Precision agriculture (PA), or site-specific crop management, is a farming concept based on observing, measuring and responding to variability across and between fields. These practices have expanded in tandem with technologies such as global positioning system (GPS) and various remote sensing and imagery techniques and autosteer machinery guidance systems.

The idea behind PA is that the more accurate you can be, the more uniform your crop is and the lower the production costs can be. It all adds up to being more profitable.

This poster provides a snapshot of variable rate application, the options available, why and how to do it, key questions to keep in mind and more information on the practical tips and tools available.
