Midwest Crop Tour – Day 4 Reports (August 24, 2017)

Pro Farmer U.S. 2017 Corn and Soybean Crop Estimates

Corn: 13.953 billion bu.; Average yield of 167.1 bu. per acre
Corn +/- 1% = 14.093 billion bu. to 13.813 billion bu.; 168.8 bu. to 165.4 bu. per acre

Soybeans: 4.331 billion bu.; Average yield of 48.5 bu. per acre
Soybeans +/- 2% = 4.418 billion bu. to 4.244 billion bu.; 49.5 bu. to 47.6 bu. per acre

Note: These estimates are based on assumptions for normal weather through September. Weather next month will be especially important as an earlier-than-normal frost/freeze would damage later-maturing corn and soybeans. We raised harvested soybean acres by 500,000 to 89.231 million acres. Initial Farm Service Agency Certified acreage indicated soybean acres will be higher than estimated than in the June Acreage Report. We made no change to corn acreage.

Crop Report for Central-Southern Minnesota


  • Central MN crop looks good
  • SE MN looks good with some variability
  • Will need some heat next 2-3 weeks to finish crops


  • Very little disease pressure although watch as temperatures cool
  • Crop is progressing very well
  • 75% good to excellent condition
  • 300 GDUs behind compared to this time last year


  • Pod development and pod counts looking good
  • Some issues with stand emergence due to planting condition challenges
  • Starting to see White Mold pressure with recent cool & humid weather

April 28th corn just starting to dent in Fillmore County Minnesota.

April 28th corn just starting to dent in Fillmore County Minnesota. GDU accumulation is running 75-150 behind the 10 year average in the area and about 300 GDU's behind 2016.

This western corn rootworm was observed in Olmsted County, MN.

Disease and insect pressure has been low in Southeast MInnesota, however we have observed an increase in corn rootworm beetles. This western corn rootworm was observed in Olmsted County, MN.

Soybeans are into R5 stage in Winona County Minnesota.

Soybeans are into R5 stage in Winona County, Minnesota. August rains are benefitting pod counts and pod fill. Cooler temps, rain, and heavy morning dew has resulted in White Mold developing across the area.

Pro Farmer Crop Report

Eastern Route - Day 4
Starts in Iowa City, IA and ends in Rochester, MN

On his first nine stops through districts 6 and 3 in eastern Iowa, Pro Farmer Editor and Eastern Tour Leader Brian Brian Grete pulled an average corn yield of 182.8 bu. per acre, with a range of 154.8 to 206.9 bu. per acre. For soybeans, his route found an average pod count in a 3'x3' square of 1,278.7, with samples ranging from 709.8 pods to 2,007.7 pods.

"We knew this would be some of the best crop on Tour, and that has proven to be the case," he reported. While there is still some variability with the crop, uniformity is much better than it was the first three days of Tour, he explains, adding that plant health has improved and the range on yield samples has tightened up on both corn and soybeans. Overall yields and pod counts have also climbed, Brian adds.

Pro Farmer Crop Report

Western Route - Day 4
Starts in Spencer, IA and ends in Rochester, MN

Today Pro Farmer Editorial Director and Western Tour Leader Chip Flory has sampled fields from the southern Minnesota crop districts 7 and 8, with his corn samples ranging from 149 bu. to 226 bu. per acre, with an average yield of 195.1 bu. per acre. On soybeans, samples on his route ranged from 703 pods to 1,224 pods in a 3'x3' square, with an average pod count of 941.

He reports that this area of the country enjoyed a pretty good growing season and the corn crop shows it. The crop "may be a touch behind," according to Chip, but he continues that it should be able to make it to the finish line without issue, so long as the crop avoids an early-September frost.

Chip was again disappointed by pod counts on his route and said he encountered white mold as he moved into Waseca County (district 8). He says that will knock down some fields. Otherwise, Chip reports plant health was good and storm damage was no worse than normal.

How Midwest Crop Tour Scouts Gather Data


The Midwest Crop Tour dates to 1987. Pro Farmer was an original participant, then agreed to take over as its organizer in 1993 and began publishing the Crop Tour’s results as a service to the agricultural community at large. Crop Tour helps “level the playing field” by providing all market participants with access to information, unlike the many ongoing private assessments of Midwest crops.

In 2000, Crop Tour was expanded to its current scale. Crop Tour supporters like DuPont Pioneer enable Crop Tour to survey a large geographic area, host daily grower meetings, and provide more extensive media coverage of the Crop Tour findings.

Conducted the third full week of August each year, Pro Farmer Midwest Crop Tour is the most widely followed “field survey” for corn and soybeans during the critical crop development period that happens in between USDA’s August and September crop surveys.


More than 100 “scouts” (farmers, media, agribusiness, and Pro Farmer staff) are organized into teams that fan across 20 pre-determined Midwest routes Monday through Thursday. Scout teams travel in vehicles which prominently display “Midwest Crop Tour” decals. In addition, each scout wears Crop Tour logo apparel so that all Crop Tour participants are readily identifiable by farmers and landowners.

The “Eastern leg” begins sampling in western Ohio, working its way across Indiana, Illinois, eastern Iowa and then southern Minnesota. The “Western leg” begins in southern South Dakota, then across eastern Nebraska, western Iowa and into southern Minnesota. Both sides of the Tour conclude in Rochester, Minn., on Thursday night.

Scouts attend a training session prior to Crop Tour and each team of about 2 to 4 people includes at least 1 experienced scout. The assigned routes that the scout teams travel have been consistent over the years to assure comparability.

Crop scouts walk fields in seven states during the Crop Tour.

DuPont Pioneer agronomists and more than 100 volunteer crop scouts will tabulate measurements taken from corn and soybean fields during the 4-day crop tour.

Field Selection

Teams pull onto rural side roads every 15-20 miles from their primary route and stop at survey locations that meet the following criteria:

Crop Sampling and Data
Crop Tour sampling and measurements are designed to get representative results for crop districts, states, and the entire Midwest – not individual fields or counties.

  • Safe parking available on a wide shoulder or field driveway
  • Accessible corn/soybean fields that are not fenced or posted
  • No structures such as homes, machine sheds, grain bins, or livestock buildings
  • Scouts measure 3 ears of corn or count pods on 3 soybean plants from just 1 location in each field surveyed. Each sample is identified by county so it can be tabulated by crop district, but is not associated with a specific field or farm location. Care is taken to move in and out of each field quickly, without damage.
Corn grain length and girth are measured during the Crop Tour.

Several measurements such as grain length and girth of corn ears are taken to estimate corn yields.
