How the war in Iran is altering planting plans for American farmers

For farmers, the war in Iran has meant changing crop rotations, using less fertilizer, investing in what is profitable, and praying costs go back down by 2027, reports Patrick Thomas of The Wall Street Journal. For his report, Thomas profiled three farmers who are responding to the challenges. 

In Iowa, farmer Dave Walton has opted to plant more soybeans than corn to avoid soaring fertilizer costs resulting from the closure of the Strait of Hormuz. Thomas explains, "Soybeans require less fertilizer to grow than corn. . . . Walton typically splits his land for half to grow corn and half for soybeans. This year, he is shifting to a 60/40 split." Walton still plans to plant all of his 1,000 acres, but he figures his costs so far in 2026 are up 20%.

Timothy Jones typically grows corn and beans, alongside raising beef cattle on his Kentucky farm. "This year, he is planning to put about 20% of his corn crop into producing hay to help feed his growing cattle herd, which is making money, and an extra 15% into more soybeans to cut fertilizer costs," Thomas adds. Since corn needs far more urea fertilizer to provide nitrogen than soybeans, that switch will save Jones money. "Urea was about $520 a ton in January, he said; now it is more than $850 a ton."

Greg Amundson, a row-crop farmer with 3,000 acres in North Dakota, isn't changing his crop choices, but he does plan to use far less fertilizer. Thomas writes, "Because of rising crop-seed costs, he is cutting back on the number of seeds he plants per acre. He is hoping that improvements in how the seeds perform when planted will compensate for using less of them."
