On a scorchingly hot day in the American Midwest, Tim Maxwell is voicing his fears about the future of farming.
The 65-year-old has worked the fields since he was a teenager. He now owns a grain and hog farm near Moscow, Iowa - but he's unsure about its prospects.
"I'm in a little bit of a worried place," says Mr Maxwell, who wears a baseball cap bearing the logo of a corn company.
He is concerned that American farmers aren't able to sell their crops to international markets in the way they could in previous years, in part because of the fallout from President Trump's tariffs.
"Our yields, crops and weather are pretty good - but our [interest from] markets right now is on a low," he says. "It's going to put stress on some farmers."
