Iowa corn crop surges ahead of schedule after hot, dry week
By John Damon | Just The News Iowa
After weeks of lagging behind, Iowa's corn crop has made a dramatic leap forward, now outpacing both last year's pace and the five-year average. The latest U.S. Department of Agriculture crop progress report shows that 38% of Iowa corn acres had reached the silking stage as of July 12, a significant jump from just 8% the week before.
This puts the current crop 9 percentage points ahead of the five-year average and 5 points ahead of the 2025 crop, according to the USDA report covering July 6-12.
Corn condition remains strong
Despite the rapid development, corn condition across the state remains stable. The USDA rated 78% of Iowa corn acres in good or excellent condition. Soybeans also fared well, with 74% rated good to excellent.
The percentage of soybean acres blooming also surged, reaching 56% — 5 points ahead of last year and 6 points ahead of the five-year average. Sixteen percent of soybean acres were setting pods, slightly behind last year but ahead of the historical average.
Dry weather helps some farmers
The July 6-12 period was unseasonably dry, according to State Climatologist Justin Glisan, who reported a statewide average precipitation of just 0.66 inch. While some fields are feeling the pinch, many farmers see this as a welcome change after years of excessive rain.
Stu Swanson, chair of the Iowa Corn Growers Association and a farmer in Wright County, said his cropland is a little on the dry side, but he prefers that to the alternative.
I would take some more rain, but the previous two years, we've had excess rain and really suffered production wise because of it. So I'd rather be just on the dry side instead of just on the wet side.
Swanson noted that his soybeans are beginning to set pods and his corn is starting to tassel and silk. He emphasized that the next week is critical for corn pollination.
Next week will really be a real key week in the state of Iowa for corn pollination. A little cooler the next week or 10 days would set us up for a really good fall and harvest.
Temperatures above normal, rain outlook mixed
Iowa's statewide average temperature for the reporting period was 77.4 degrees Fahrenheit, more than 2 degrees above normal. The National Weather Service predicts above-average temperatures and slightly below-normal precipitation for the coming week.
Soil moisture remains mostly adequate, with 73% of topsoil and 69% of subsoil rated as having adequate moisture.
What this means for Iowa agriculture
For Iowa farmers, the rapid crop development is a positive sign, but the next 10 days will determine whether this year's harvest meets expectations. Cooler weather during pollination could set the stage for a bumper crop, while continued heat and dryness could stress plants.
Swanson's cautious optimism reflects the mood of many in the state's agricultural community. After years of weather extremes, Iowa farmers are hoping for a balanced season that delivers strong yields.
