At least 1 million acres (405,000 hectares) of U.S. farmland were flooded after the “bomb cyclone” storm left wide swaths of nine major grain producing states under water this month, satellite data analyzed by Gro Intelligence for Reuters showed.

Farms from the Dakotas to Missouri and beyond have been under water for a week or more, possibly impeding planting and damaging soil. The floods, which came just weeks before planting season starts in the Midwest, will likely reduce corn, wheat and soy production this year.

“There’s thousands of acres that won’t be able to be planted,” Ryan Sonderup, 36, of Fullerton, Nebraska, who has been farming for 18 years, said in a recent interview.

“If we had straight sunshine now until May and June, maybe it can be done, but I don’t see how that soil gets back with expected rainfall.”

Spring floods could yet impact an even bigger area of cropland. The U.S. government’s National Oceanic and Atmospheric Administration has warned of what could be an “unprecedented flood season” as it forecasts heavy spring rains. Rivers may swell further as a deep snow pack in northern growing areas melts.

The bomb cyclone of mid-March was the latest blow to farmers suffering from years of falling income and lower exports because of the U.S.-China trade war.

Gro Intelligence analysts cautioned the satellite imagery did not show the full extent of flooding in Nebraska, where officials declined to provide acreage estimates to Reuters, or in North Dakota. Nebraska’s governor has said the floods caused agricultural damage of $1 billion in his state.

Cloud cover or snow on the ground makes it difficult to identify the flood waters in NASA satellite data, said Sara Menker, chief executive of the agricultural artificial intelligence company.
