On the heels of Crop Tour, Pro Farmer projects corn yields at 6.1 bu. below USDA’s August estimate, while soybean yield numbers are nearly aligned.
The Minnesota corn crop is going for gold. Pro Farmer Crop Tour scouts expect the crop will reach a record 202.86 bu. average, if it can outpace southern rust and tar spot. Scouts peg the Iowa corn crop at a 198.43 bu. average, but it also faces disease challenges.
Iowa could be the nation’s top state this year for corn and soybeans, but both crops are in a race to beat disease pressure that’s gaining momentum. Illinois corn continues to ride the struggle bus, while the soybean crop there is positioned to deliver high yields.
There is still up to 55% of the kernel dry weight left to be accumulated by many corn hybrids at this point — starch that can contribute significantly to grain fill and higher test weights.
With at least four weeks left in the growing season, Ferrie encourages farmers to stay ahead of heavy disease pressure in fields, particularly in what he calls D hybrids — those that punch their yield card late-season.
Corn yield estimates in seven counties surrounding the community of Bloomington indicate farmers there will harvest an average crop, at best. That’s counter to what USDA predicts for Illinois yield results statewide.
Camaraderie is cathartic. It lifts spirits, gives encouragement and reminds all of us we are valuable. Check out what farmers have to say about this year’s corn crop – the good, the bad and the in-between – and may their experiences lighten your load in the process.
USDA reports 73% of the corn crop nationally is in good to excellent condition – a 5% increase over this same time in 2024. Industry analysts believe the Aug. 12 Crop Production report will boost its estimate for the 2025 crop because of the overall favorable growing season.
Nebraska grower Brian Herbek says a ‘finishing pass’ can help fill corn ears all the way to their tips with kernels and pack on more starch in the process. Hear more of Herbek’s insights along with David Hula and Randy Dowdy on Breaking Barriers With R&D.
Just as corn growers were ready to put their pollination problems behind them, another one comes along. This time, the issue had to do with moisture occurring at the wrong time, and the results are significantly impacting yield.
The Midwest has been inundated with rain, heat, oppressive humidity and “corn sweat”. In fact, meteorologist Ryan Maue says the heat index hit 115°F Sunday night in Iowa — and 20°F to 25°F of that was coming from surrounding corn fields.
Both diseases are showing up earlier this summer than last year, according to Daren Mueller, Iowa State University plant pathologist. He says a new interactive tool from the Crop Protection Network can help farmers locate these diseases, and others, faster.
So far, the problem has been confirmed in four states. Agronomists are encouraging farmers to scout crops, estimate yield impacts in affected fields and determine whether to make adjustments to marketing plans.
As big yield estimates are being thrown around so early, it’s stoking an intense debate. However, that’s not stopping the trade chatter. With talk of a new national corn yield record, it’s pressuring prices, with many farmers staring at cash corn with a $3 handle.
Unlike most leaf diseases, tar spot starts impacting the crop at the bottom of plants. That means fungicides you apply must penetrate and get deep into the crop canopy to provide effective treatment. If you opt to not treat the disease, consider making plans to harvest early and pre-booking some dryer gas.
That percentage doesn’t tell the complete story, however. While farmers in the West and southeast Texas have endured weeks of dry conditions that’s not been the case in the central Corn Belt where growing conditions have been excellent.
With product and application costs totaling between $30 and $40 per acre, farmers will be taking a harder look at where they make the investment this season.
The silver lining, meteorologists say, is many farmers and livestock producers in the central and eastern U.S. have had sufficient moisture this spring and milder temperatures headed into summer. For some, that’s about to change.
Iowa corn quality leads the nation currently, with 83% of the state’s crop rated good to excellent. North Dakota is on the struggle bus for both corn and soybeans.
Now’s the time to be scouting for the disease, especially where the inoculum is present. Tracking weather data, particularly daily humidity levels, can help you keep an eye on tar spot this season.
This spring turned into the wettest in over a century for parts of the U.S. As the focus shifts to June, the moisture in the ground will help keep the heat down, but the pattern is also turning drier for two Midwestern states.
From emergence to maturity, nitrogen is a crucial nutrient for corn, but plants have different nitrogen demands at different growth stages. Consider how corn yields are influenced by nitrogen at VE, V6, V10-V12 and R5-R6.
It’s not just planting cotton farmers are battling this year. Soybeans are also struggling in the ground, and the corn is wind whipped or battered by hail and sand. With farmers staring at financial losses already this year, some worry this could push a growing number of them out of business.
The start of June could bring high heat and drier weather, which is a stark contrast from the forecast for the last week of May.
USDA meteorologist Brad Rippey says climate models have consistently shown a ridge across western North America that could lead to drought development, drought continuation or even drought expansion across portions of the Plains and West.
Knowing the final plant population as well as the uniformity of the stand can guide you in deciding whether you will benefit most from keeping the current crop or ripping it out and replanting, says Missy Bauer, Farm Journal Field Agronomist.
Parts of the Central and Southern Plains are seeing some beneficial rains, but did they come in time to improve the winter wheat crop? Farmers will know soon, as harvest generally begins in early to mid-June.
Despite wet weather, farmers are making serious progress with planting. Here’s an update on how the season is shaping up in Iowa, Minnesota, Wisconsin and Illinois.
Drew Lerner, founder of World Weather, Inc., says the summer of 1968 had some strong patterns, including a wetter bias in the western and north-central U.S., but drier in most of the Atlantic Coast states and parts of the eastern and southern Midwest.
A handful of rain-free days were a perfect recipe for spring planting — and farmers took full advantage of the opportunity. This week’s USDA crop progress report puts corn and soybean acres just ahead of last year’s pace.
