Kuhn reckons that changing application rates has never been simpler than with EasyMaps, a variable rate application map for smart phones and tablets.

The company reckons that 4% of the European land area is covered by variable rate application maps, and of this 60% is done manually. Many farms simply print out the map, stick it to the windscreen, and guess when to vary the rates.

Providing simple changing of application rates in the field using a smartphone or tablet, EasyMaps displays application maps in real time, and indicates the required rate and variation percentage. It is not necessary to have a dedicated GPS system in the tractor cab. The driver simply changes the settings on the machine terminal.

Compatible with all types of application maps, it also displays the areas already worked in the field making night-time operations easier. Available for anyone to download, the app is free and available at Google Play and Apple Store.
