Take a break from harvest, and head up to Yakima on October 20-22 for FIRA!

See Ag robots, sensors, and other innovations in action, and talk to the teams designing these tools. It's a great chance to discuss farm needs (and wants .... and dislikes!) to help shape the future of ag support technology!

The event is no longer only about robotics but now embraces AgTech, addressing the specific needs of the Pacific Northwest such as irrigation, canopy management, tillage, and more.
