Takeaway

Midwestern corn and soybean harvest progress is showing stark regional divergence, driven by summer heat-induced early maturation in some areas and severe recent rain delays in others. Field reports indicate mixed production outcomes: corn yields are generally trending below historical or prior-year levels across Iowa and Illinois, while soybean yields are outperforming expectations despite late-season moisture threatening crop quality.

What the presenter said

• Percival, Iowa: Extreme summer heat accelerated corn maturity, triggering the earliest harvest on record starting September 11th, despite planting being 9 days late on April 19th [00:14, 00:20, 00:48].
• Percival, Iowa Yields & Weather: Corn yields are averaging ~225 bpa (vs. 240 bpa normal), impacted by lower stand counts from cool post-planting emergence, though later-planted May corn may yield better due to pollination rains [02:05, 02:30, 02:44]. Recent consecutive rains halted harvest for an estimated week [01:13]. Soybean yields are targeted in the upper 50s bpa, with low disease pressure noted across both crops [01:38, 03:26].
• Newell, Iowa: Harvest is stalled following nearly 9 inches of rain over the last 30 days, causing severe quality degradation including corn sprouting in the husk and soybeans sprouting in the pod [03:37].
• Mankato, Minnesota: Harvesting has not commenced due to persistent rains; soybean stalks are beginning to rot, though corn stands remain intact [03:48].
• Maroa, Illinois: Corn yields are lagging prior-year results by 20 to 30 bpa, while soybean yields are coming in strong at 75 to 85 bpa [04:02].
• Carthage, Illinois: Corn harvest is ~30% complete with yields down ~10% year-over-year; soybean combining has just commenced [04:15].
• Cresco, Iowa: Harvest remains on normal schedule for early October, with crops nearing maturity ahead of forecasted weekend precipitation [04:24].

• Percival, IA Corn Yield: ~225 bu/acre current year vs. 240 bu/acre normal year (Pat Sheldon).
• Percival, IA Soybean Target Yield: Upper 50s bu/acre (Pat Sheldon).
• Percival, IA Planting & Maturity: 110-day corn; planted April 19th (9 days past April 10th federal crop date).
• Newell, IA Rainfall: Nearly 9 inches over the last 30 days, plus an additional 1 inch last week (Matt McCarthy).
• Mankato, MN Rainfall: Roughly 1 inch last week (Chris Schenk).
• Maroa, IL Corn Yield: 20 to 30 bu/acre below last year (Cody White).

Risks and what would invalidate this

• Excess Moisture & Delays: Further heavy rainfall stalling field progress and compounding harvest delays.
• Crop Quality Degradation: Continued sprouting of corn in husks and beans in pods, alongside stalk rot in soybeans due to excessive field moisture.
• Yield Drag: Compounded yield loss from summer heat stress and reduced stand counts caused by poor early-season emergence.
