Twenty-one state corn grower groups, including North Dakota, Minnesota and South Dakota, commissioned a Texas A&M fertilizer study. This research says the supply chain disruptions influenced the price and supply of nitrogen products. South Dakota Corn Growers Association President Scott Stahl said the threat of tariffs is also concerning. “Four companies control nearly 80 percent of the nitrogen in this country, so this tariff coming in raising the price for something that is imported and sets the benchmark for the rest of the fertilizer market,” said Stahl. “It doesn’t seem to be functioning like a true market should.”
