Want to turn your roadside crop into an advert?

It could soon be possible, thanks to Kverneland’s new Optima GEOseed system, which brings GPS accuracy to precision maize drilling.

So as well as giving sprayer-style auto shut-off at headlands, it means that the drill can control the GPS position of every single seed. It also means that seeds can be planted in patterns that give every plant the maximum amount of light and make mechanical cross-hoeing possible.

Another, faintly wacky, advantage of this technology is foreseen by the Norwegian machinery giant. By adding an individual seeding map (now available from firms like Landdata Eurosoft) it means you can drill in a way that allows a maize maze to be automatically created.

Another possibility (which could yield a bit of extra income) is to create advertising slogans by precision-drilling them in roadside fields.
