Driverless tractors are already operating on some U.S. farms. Automation offers benefits, but farm workers worry.

The harvest is plentiful and the workers are robots. That's the plan for some U.S. farms. "A growing number of companies are bringing automation to agriculture. It could ease the sector’s deepening labor shortage, help farmers manage costs, and protect workers from extreme heat," report Melina Walling of The Associated Press and journalist Ayurella Horn-Muller. "Automation could also improve yields by bringing greater accuracy to planting, harvesting, and farm management."

Florida farmer Jeremy Ford was tired of wasting water and using fossil fuel-run equipment to care for his crops, so he turned to an automated underground system, "that uses a solar-powered pump to periodically saturate the roots of his crops, saving 'thousands of gallons of water,'" Walling and Horn-Muller explain. "Although they may be more costly upfront, he sees such climate-friendly investments as a necessary expense — and more affordable than expanding his workforce of two."

What about automated harvesting? "On some farms, driverless tractors churn through acres of corn, soybeans, lettuce and more. Such equipment is expensive, and requires mastering new tools, but row crops are fairly easy to automate," AP reports. South Dakota farmer Frank James along with his family members, "swear by tractor 'autosteer,' an automated system that communicates with a satellite to help keep the machine on track. . . [but] requires human oversight to work as it should."

While some agriculture stakeholders have pushed back against automation, some farmers look to the technology's potential to increase profitability and decrease business headaches. Walling and Horn-Muller report, "Will Brigham, a dairy and maple farmer in Vermont, sees such tools as solutions to the nation’s agricultural workforce shortage. Since 2021, Brigham’s family farm has been using Farmblox, an AI-powered farm monitoring and management system that helps them get ahead of issues like leaks in tubing used in maple production."

Robotic farm tools may make caring for crops during extreme heat more efficient without putting human workers at risk. "Extreme heat, drought and intense rainfall have made labor-intensive corn detasseling even harder," Walling and Horn-Muller write. 

Even with its benefits, automated farming may affect farm worker employment. "Automation can be a 'tactic, like a strategy, for bosses, so people are afraid and won’t demand their rights,' said Luis Jimenez, a New York dairy worker. Robots, after all, 'are machines that don’t ask for anything,' he added. 'We don’t want to be replaced by machines.'"
