Do you believe rising agricultural production costs will result in higher prices for your groceries?

Farmers across South Dakota are navigating a difficult harvest season marked by corn stalk disease and inconsistent weather patterns. Operators are forced to slow down harvest speeds to recover crops damaged by stalk rot, crown rot, and localized weather extremes.

Why it matters

The confluence of crop disease, summer drought in the east-central region, and rising operational expenses creates significant financial strain for producers. These factors complicate yield expectations as farmers work to finalize the 2026 harvest while planning for the 2027 season.

Diesel fuel prices have surged 60 to 70 percent higher compared to the spring of 2026. Implement dealers are also reporting a notable spike in sales for corn snouts and shafts as operators manage damaged stalks.

The details

Harvest operations have been hampered by late soybean harvesting and severe field conditions, including corn in the southeast that failed to develop ears. To manage the tangled or flat stalks, operators are utilizing specialized combine corn heads and reducing their overall speed.

Mid-July through late August 2026: East-central South Dakota faced a period with no rainfall.
Spring 2026: Diesel fuel costs were significantly lower than current autumn levels.
October 2026: Farmers are currently executing active harvest operations.
2027: Producers are preparing for the upcoming growing season.

Market Landscape

This season reflects the broader industry trend of rising input costs for midwestern crop production, which forces farmers to manage tighter profit margins. Producers are navigating these pressures while adapting to localized weather impacts that diverge from standard seasonal averages.

Increased production costs and harvest difficulties may influence regional commodity supply and pricing for the coming year. These factors ultimately contribute to the financial risk profile for local agricultural operations heading into 2027.

The takeaway

Producers should prioritize equipment maintenance and careful harvest management to salvage as much of the corn crop as possible from damaged fields. Long-term financial planning is essential to account for the sustained rise in fuel and fertilizer expenses heading into next year.
