The “bomb cyclone” left at least 1 million acres (405,000 hectares) of U.S. farmland flooded.
Wide swaths of nine major grain producing states are under water–farms from the Dakotas to Missouri and beyond have been under water for a week damaging soil and likely to reduce corn, wheat and soy production.
The mid-March bomb cyclone was the latest blow to farmers, as well as damaging to roads and railways.
The water has also destroyed billions of dollars of old crops that were in storage.
Because of the U.S.-China trade war, the farmers suffered from years of falling income and lower exports.
Spring floods could yet impact an even bigger area of cropland.
The extent of the flooding had previously not been made public.
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.
