Drought
The crop took it on the chin this season, with some Iowa farmers reporting huge yield losses as harvest gets underway. A one-time fungicide application helped, but it wasn’t enough to buck severe disease pressure, allowing it to return.
The crop is drying down rapidly, given the weather conditions across much of the country. Agronomists are concerned farmers will combine fields too late and advise starting at 13% moisture or even higher.
Agronomic specialists are encouraging farmers to make their corn harvest plans now, prioritizing which fields to combine first and so forth. Evaluating how well the crop is standing on a field by field basis can help you plan the process and minimize having to pick up down corn.
Crops in parts of the Corn Belt may have run out of gas with the onset of flash drought. As a result, the crop may be going backward from USDA’s August estimates.
Will this be the summer of drought that never fully materialized for these two crops? While there are areas of dryness, both continue to flourish. Here’s a look at how August weather is expected to finish out this week across the country, as September comes into view.
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.
More reports of ‘overly tight tassel wrap’ are coming in across the Corn Belt – including from the reigning world champion corn grower. Hula shares how he strategically uses his planter to minimize pollination risks.
Portions of the central Plains, the Upper Midwest and the Mid-Atlantic will be in a heat dome by Tuesday. But first, those regions will see thunderstorms and heavy rains this weekend, according to the National Weather Service.
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.
The $16 billion in disaster aid covers crop losses due to natural disasters from 2023 and 2024. It’s the largest chunk of the $21 billion approved by Congress at the end of 2024.
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.
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.
The third round of disaster aid payments through the Supplemental Disaster Relief Program is the largest amount appropriated by Congress. USDA Deputy Undersecretary Brooke Appleton says those payments are being prepared now.
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.
Dust storms can occur anywhere there’s loose soil and wind. Along with Illinois, states including Indiana, Kansas, Missouri, New Mexico and Texas have also experienced the problem this year.
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.
