Michigan farmers are facing a difficult growing season due to rising fertilizer prices and excessive rainfall. These challenges are affecting soil nutrients, crop growth, and overall farm productivity. Fertilizer supply has been impacted by global disruptions, especially due to the U.S. war with Iran, which has blocked important shipping routes.
About 20% to 30% of the world’s fertilizer exports pass through the Strait of Hormuz. With this route disrupted, fertilizer availability has decreased, causing prices to rise sharply. Urea fertilizer, which provides nitrogen, increased from $580 per ton in February to $775 per ton in May, showing a significant price increase. Fertilizer prices had already been rising due to other global issues, including the war in Ukraine and export restrictions from China.
“Corn is very, very dependent on nitrogen,” Knudson said. “Corn uses a lot of nitrogen to grow so corn farmers are facing a really difficult year this year.”
Although many Midwest farmers pre-booked fertilizers in advance, about one in three still reported not having enough supply for the season. This shortage has made it harder for farmers to manage their crops effectively.
At the same time, Michigan has experienced heavy rainfall and flooding. Excessive rain affects soil nutrients by causing nitrogen loss through a process called leaching. Studies show that too much rain can harm crops as much as drought, especially in colder regions where water evaporates more slowly.
Phosphorus levels in the soil are also reduced due to heavy rainfall. This not only affects crop growth but also leads to environmental issues.
“Whenever there’s heavy rainfall or a continuous rainfall that has added a lot of water into the ground, some of the phosphorus that’s in the soil is going to get released,” Ghane said. “When the concentration of phosphorus is high and you add warmer temperatures to it, the algae start growing rapidly.”
Loss of phosphorus can cause algal blooms in water bodies like the Great Lakes. Farmers can manage some of these losses through better water and soil management techniques, but complete prevention is difficult.
In addition to fertilizer challenges, farmers are facing rising diesel costs, adding more pressure on farm budgets.
“Diesel prices are way up and farmers are big users of diesel,” Ghane said. “That’s also a major consideration and a major source of stress on farm profits.”
Experts warn that such combined challenges could seriously impact farmers’ livelihoods.
“Some farmers will probably go out of business this year,” he said.
