Russell Ranch Sustainable Agriculture Field Day 2013

 RR field day banner

This spring, the wireless gadgets were buzzing and texts were flying as new agricultural technologies were discussed at the Russell Ranch Field Day. The field day took place on May 28, 2013 with the theme "Harnessing Technology for Agriculture." Researchers, extension, students and industry presented on technological innovations in agriculture that can change the way agriculture addresses irrigation and nutrient management. Presentations included new technologies like cellular text messaging for surface irrigation monitoring with Shrini Upadhyaya, Toby O'Geen's presentation on SoilWeb and Micah Eidem's (Trimble) presentation on the GreenSeeker crop sensor. The grower's panel, moderated by Gene Miyao, with Fritz Durst, Rick Martinez, Dustin Timothy and Frank Muller, covered topics on current issues with drip and furrow irrigation, as well as needs for new technologies.
