Farmers across Iowa took full advantage of a warm, dry week to move forward with corn and soybean harvests, with combines rolling across the state, according to Iowa Secretary of Agriculture Mike Naig. The latest USDA Crop Progress and Condition Report shows that as of September 28, 17% of soybeans and 15% of corn acres had been harvested statewide.

While soybean harvest is trailing the five-year average by about three days, corn harvest is running four days ahead of last year and one day ahead of the average pace. Naig noted that with continued favorable weather expected, farmers should keep "making harvest headway," though he warned that field conditions may be dusty due to low rainfall.

The accelerated corn harvest aligns with a broader trend across the U.S., where 18% of corn acres have been harvested, slightly behind soybeans at 19% nationwide. The week's temperatures averaged 8.1°F above normal, which helped advance crop maturity significantly. Iowa's corn maturity jumped from 66% to 80%, and soybean leaf drop surged from 62% to 83%, signaling rapid harvest readiness.

Crop quality remained stable, with 55% of soybeans and 53% of corn rated in good condition, and 18% of each crop rated excellent. Despite below-average rainfall-just 0.41 inches statewide-soil moisture levels are still mostly adequate for this stage of the season.

Across Iowa, 65% of topsoil and 70% of subsoil moisture conditions were rated adequate. Regional disparities, however, were evident: southeast Iowa reported just 33% adequate topsoil moisture, with 66% rated short or very short, while central and northern Iowa fared better.

The seven-day outlook from the Iowa Department of Agriculture and Land Stewardship projects less than half an inch of rainfall, meaning harvest conditions are likely to remain dry in the near term. While this continues to support machinery access, prolonged dryness could begin to impact later-harvested acres if not balanced with moisture recovery.

As October progresses, Iowa farmers will continue pushing through the critical early weeks of harvest, balancing yield preservation with the logistical pressures of moving grain under variable soil and weather conditions.
