U.S. agricultural exporters are bracing for a rough harvest season that seems likely to result in dramatic reductions in crop prices, thanks in large part to overseas retaliation for President Trump’s tariffs on billions of dollars worth of imports.

By one measure, U.S. farmers haven’t lost anything yet. The June trade numbers released last week showed U.S. farm exports at $14 billion, just a shade under May’s level and still on pace to beat the value of exports seen in calendar year 2017.
