RESEARCH AT Iowa State University shows that precise spraying of crop protection products through autoguidance on a sprayer saves product by eliminating overlap.

How much is saved is “dependent on field size and shape as well as the original configuration of the machinery,” explains Matt Darr, a precision ag specialist at Iowa State University.

Autoswath plus autosteer on sprayers is justified if you spray 1,800 acres/year assuming a five-year equipment life, Darr says. “This typically relates to 900 farmed acres per year since most acres are sprayed twice,” he adds. — Jodie Wehrspann
