Rising production costs and unpredictable tariff decisions are squeezing American farmers ahead of the November 3, 2026, congressional midterm elections, creating a crucial political test for Donald Trump’s administration in key agricultural states like Iowa.
The Rising Field Costs Behind the Harvest
The dark green harvester moves in straight lines across the cornfield, chewing through thick stalks while the tank fills with gold-yellow kernels. For Zach van Arkel and his father, the three-week harvest across 800 hectares of soy and corn near Grinnell, Iowa, dictates financial survival. Yet the math behind this year’s yield remains deeply uncertain as operational expenses surge.
Fertilizer, plant protection products, land expenses, machinery, and replacement parts continue to climb. Van Arkel spent 500,000 dollars solely on fertilizer this season, pushed upward by the war in Ukraine. Meanwhile, every tank of diesel for the harvester costs 1,000 dollars, an expense linked directly to the war of the US against Iran.
Despite these mounting pressures, van Arkel maintains support for the current administration. He notes that he cannot draw a direct line between government policy and current circumstances, emphasizing that farmers focus strictly on what they can control.
Market Volatility and Agricultural Policy
From the harvester, the harvested grain moves straight into the grain cart and storage silo, awaiting a market characterized by extreme daily price swings. Prices shift rapidly depending on shifting tariff policies, federal subsidy promises, and trade negotiations involving soybean exports to China or corn-based ethanol agreements with Canada and Europe.
Van Arkel points out that government intervention forces producers to question whether they are running independent businesses or merely acting as chess pieces. While farmers bear the complete financial risk, they question whether elected officials listen to constituents or focus strictly on campaign donors.
At the Iowa State University in Aimes, Dr. Sunghun Lim calculates the agricultural damage stemming from this political uncertainty. His research shows that policy volatility creates hidden expenses that small agricultural operations struggle to absorb.
| Factor | Primary Impact on US Farms | Underlying Cause |
|---|---|---|
| Fertilizer Expenses | High input costs | War in Ukraine |
| Fuel Costs | $1,000 per harvester tank filling | War of the US against Iran |
| Trade Volatility | Unpredictable daily crop pricing | Tariff policies, shifting export deals |
| Livestock Margins | Threat of unprofitable beef operations | Announcement to import beef from Brazil |
While federal insurance programs exist to cover crop failures and severe weather, no safety net protects producers from executive policy shifts. Large corporations absorb these regulatory shocks easily, but small farms lack the financial resilience to withstand repeated policy reversals.
Political Frustrations Ahead of the Midterms
Similar instability frustrates Berleen Wobeter and her husband Pete, who manage a smaller farm near Toledo, Iowa, producing corn, soybeans, and beef. Plans to restock their cattle herd stalled after Trump announced plans to import beef from Brazil to lower domestic grocery store prices, threatening local cattle producers with a loss.
Wobeter notes that while the agricultural community traditionally votes for the Republican Party, deep divisions remain over whether current trade and economic strategies actually serve producers. This frustration led Wobeter to run for the parliament of Iowa herself as a Democratic candidate, representing farmers who feel ignored by both major political parties.
As the autumn harvest across Iowa concludes, the political harvest takes place on Tuesday, November 3, 2026, determining control of both chambers of the US Congress.
