As the 2025 harvest season winds down in Iowa, farmers are benefiting from seasonal temperatures but contending with below-average precipitation that is extending dry conditions across much of the state. According to the Iowa Department of Agriculture and Land Stewardship (IDALS), the statewide average rainfall for the last full week of October was just 0.01 inch, far below the seasonal norm of 0.63 inch. Meanwhile, average temperatures held steady at 50°F, consistent with long-term climate trends.

The dry stretch is aiding harvest progress, with fewer than 10% of soybean acres and less than 25% of corn left to harvest by late October. However, these conditions are also affecting soil moisture, residue breakdown, and limiting post-harvest fieldwork options.

State Climatologist Justin Glisan described the situation as "unseasonably dry," and the latest U.S. Drought Monitor shows that 64% of Iowa is now experiencing abnormally dry to moderate drought conditions. Frost has also made its first statewide appearance, further pressuring farmers to finish field operations.

Amid the dry finish, crop performance has been mixed. Agronomists with the Iowa Soybean Association report that soybean weights have been impacted by dry harvest conditions, while disease pressure in corn has led to yield variability across fields. The situation is further complicated by the ongoing federal government shutdown, which has delayed the USDA's weekly Crop Progress and Condition report for a fourth consecutive week-leaving farmers and markets without key production data.

With harvest wrapping up, attention is shifting toward cover crop adoption. Iowa Secretary of Agriculture Mike Naig and Governor Kim Reynolds are encouraging farmers to enroll in the state's Crop Insurance Discount Program, which offers a $5 per-acre premium discount for planting fall cover crops. This initiative, part of the Iowa Nutrient Reduction Strategy, helps reduce nutrient runoff and improve water quality. Nearly 2,000 Iowa farmers have enrolled over 1.4 million acres in the program to date.

"This voluntary and innovative program not only encourages cover crop adoption but also offers farmers a discount on their crop insurance premiums," said Governor Reynolds. "Our farmers understand the connection between soil health and crop production."

Enrollment for the insurance incentive opens December 1 and runs through January 23, with sign-up available online or through crop insurance agents.

As dry conditions persist, Iowa's end-of-season dynamics offer a clear reminder of the complex interplay between weather, input costs, and conservation strategy. For many producers, this fall could shape the outlook not just for the 2026 planting season-but for long-term resilience in U.S. row crop agriculture.
