Washington state is the nation’s top wheat exporting state – about 90% of the dryland wheat grown here is trucked or shipped by river barge to west coast ports. These buyers are eager to visit farmers and see the crop up close because they buy so much of it. Ninety percent of all the wheat grown in Washington state is exported, with some varieties coming out of test labs like this one run by the U.S.D.A. labs that operate in conjunction with scientists at Washington State University. Farmers may not want to talk politics, but Trump’s tariffs are affecting them directly, namely in higher prices for fertilizer.
