President Trump’s plan to impose a 100 percent tariff on Russian goods could raise the cost of urea, a key fertilizer in corn and other row crops.

President Donald Trump may have expected a Russian shudder of fear to greet his threat of “very severe tariffs” on the country if it didn’t agree a ceasefire in Ukraine.

Trump also revealed that Putin had recently offered to assist in mediating between Israel and Iran during their brief June conflict — an offer he declined. “I said, ‘No, no, you help me get a settlement with you, with Russia,’” Trump recounted. “And I think we're going to be doing that too.”
