(Reuters) -Archer-Daniels-Midland ( ADM ) posted a fall in second-quarter profit on Tuesday, hurt by weakness in oilseed crush margins and weak performance in its grain origination and crushing business.

The results come as the U.S.-based grain merchant braces for an impact from President Donald Trump's policies as well as plans to impose sweeping tariffs on most imports.

Trade concerns stoked by tariff fears have also disrupted trade flows and created headwinds for agribusinesses such as ADM.

Profit from Ag Services & Oilseeds, the company's largest segment, slumped 7% to $113 million in the reported quarter driven by lower margins, primarily due to lower vegetable oil demand arising out of biofuel and trade policy uncertainty.

The division houses the company's global crop trading, transportation and storage, and oilseed processing operations.

The Chicago-based company reported net earnings of $219 million, or 45 cents per share, for the quarter ended June 30, down from $486 million, or 98 cents per share, a year ago.
