Panicked farmers throughout the Midwest are facing the increasing probability that vast tracts of fields will remain unplanted or crops will fail this year as much of their land remains under water or too sodden for farm equipment and plants.

The crushing weather conditions come on top of President Donald Trump’s trade war with China that has already triggered a record number of farm bankruptcies.

It’s been the wettest 12 months ever in the U.S., and scientists link it to the effects of climate change.

“The frequency of these disasters, I can’t say we’ve experienced anything like this since I’ve been working in agriculture,” John Newton, chief economist at the American Farm Bureau Federation, told The Washington Post.

It’s the slowest planting time in 39 years.

Sodden fields lie fallow, and corn and soy crops that have been planted are stunted in the mud. Hard-hit states include Ohio, Iowa, Illinois, Indiana, Kansas, Missouri, South Dakota, Oklahoma, Nebraska and Michigan. Waters began to recede in some areas in recent days but there’s more rain in the forecast.

“It’s going to be a train wreck,” Illinois corn farmer James McCune, whose family has been tilling the soil since 1857, told Crain’s Chicago Business. He could only plant 950 acres this year of the 6,000 acres he operates.
