Iowa Secretary of Agriculture Mike Naig Monday commented on the Iowa Crop Progress and Condition report released by the USDA National Agricultural Statistics Service. The report is released weekly from April through November.
“Tuesday marks the official first day of fall and harvest is underway for many farmers across the state,” said Secretary Naig. “The drought monitor has improved in almost every part of Iowa and outlooks through the end of September indicate near ideal conditions that should keep combines rolling.”
A week without measurable rainfall allowed farmers 6.2 days suitable for fieldwork during the week ending September 20, 2020, according to the USDA, National Agricultural Statistics Service. Field activities included harvesting corn for silage, fall tillage, moving old crop grain stocks, and harvesting corn for grain and soybeans.
Topsoil moisture condition rated 12% very short, 29% short, 56% adequate and 3% surplus. Subsoil moisture condition rated 21% very short, 32% short, 46% adequate and 1% surplus.
Corn was 94% in or beyond dent stage, over 2 weeks ahead of the previous year and 4 days ahead of the 5-year average. Two-thirds of the crop has reached maturity, 3 weeks ahead of last year and over a week ahead of average. Corn harvest for grain reached 4% statewide, 17 days ahead of last year and 5 days ahead of average. Corn condition rated 42% good to excellent, unchanged from the previous week. Soybeans coloring or beyond advanced to 90%. That is over 2 weeks ahead of last year and 1 week ahead of average. Two-thirds of the soybean crop was dropping leaves or beyond, also over 2 weeks ahead of last year and 1 week ahead of average. Soybean harvest was 7% complete, 17 days ahead of last year and 6 days ahead of average. Farmers in northwest and west central Iowa led the way with over 10% of their soybeans harvested. Soybean condition rated 48% good to excellent.
Alfalfa hay third cutting was 97% complete, a month ahead of last year and over 2 weeks ahead of the 5-year average. Pasture condition rated 17% good to excellent. Livestock experienced little stress with cooler temperatures.

Cooler and drier conditions persisted across the state through the reporting period as a quieter weather pattern settled over the Midwest. High-level smoke from western wildfire produced many hazy days as temperatures were up to three degrees below average in eastern Iowa; near-normal conditions were reported across much of western Iowa with a statewide average temperature of 61.0 degrees, 1.2 degrees below normal. After the wettest week of the reporting season, no measurable rainfall was reported across Iowa, leading to deficits on the order of 0.60 inch to over 0.80 inch.
Sunny and seasonal conditions greeted Iowa Sunday (13th) afternoon as clouds finally cleared the state. Daytime temperatures were seasonal, in the mid to upper 70s with variable winds. Under clear skies, morning lows on Monday (14th) dipped into the low 50s with low-level patchy fog observed at locations around the state. Winds shifted to a southerly direction during the afternoon as temperatures pushed into the upper 70s and low 80s. Tuesday (15th) was a warmer day across Iowa as southerly winds picked up under clear skies. High temperatures peaked in the low to mid 80s, slightly warmer than normal. Overnight lows into Wednesday (16th) were in the upper 50s and low 60s with partly cloudy conditions reported in southern Iowa. A weak cold front propagated northwest to southeast through the day, shifting winds to a northerly direction and ushering in cooler air. Temperatures ranged from the low 70s north to low 80s south; southeastern Iowa reported some mid 80 degree readings. Skies stayed mostly clear allowing morning lows to drop into the mid 40s to low 50s.

A westerly wind built in through the day as cloud cover filtered across eastern Iowa. Afternoon highs remained in the mid 60s east to low 70s west, still cooler than expected for this time of year.
