HAYS, Kansas — It’s been a tough 12 months for the Wheat State’s trademark crop.
This resilient plant is a fighter. But even for a grain that’s seemingly constructed to succeed on these unforgiving plains, the continued drought exams its limits.
Wheat farmers, like Chris Tanner in northwest Kansas, really feel the curler coaster.
“It can be very, very bountiful or it can be the complete polar opposite and be a famine,” Tanner stated. “You have to learn how to weather those storms in life.”
Recently, these storms have been nearer to a Dust Bowl than a deluge.
After the rain shut off final spring, most of his wheat fields in northern Norton County ended up producing fewer than 20 bushels per acre, a steep drop from his common yields. Many of them didn’t develop sufficient to trouble harvesting in any respect.
“That was basically a complete loss,” Tanner stated. “It’s devastating to watch your crop die.”

It’s been a traditionally hot, dry, windy year throughout western Kansas. As incessant drought, sweltering warmth waves and relentless winds have pummeled the area’s fields, gaining a higher understanding of utmost weather’s impression on wheat has grow to be more and more important for farmers and the state’s multibillion-dollar agricultural economic system.
As the nation’s high wheat-producing state — rising roughly one-fifth of all of the wheat within the U.S. — the ache wheat farmers really feel right here sends ripple effects across the globe.
And a new piece of research — a collaboration between Kansas State University and different establishments from Texas to China — sheds extra gentle on precisely what these brutal situations can do to wheat crops and why excessive weather patterns may grow to be increasingly widespread right here within the coming many years.
Triple whammy
The landmark K-State study payments itself as the primary one to compute the impression of a altering climate on wheat farming within the Great Plains. It analyzed how completely different mixtures of weather add up to have an effect on the grain’s manufacturing throughout six states — Kansas, Colorado, Nebraska, South Dakota, Oklahoma and Texas.
The objective was to reply some easy questions with 4 many years of detailed information. What occurs to wheat when the weather is scorching? Or dry? Or windy? And what about when two or three of these atmospheric situations hit the identical subject on the identical time?
Unsurprisingly, the triple whammy of scorching, dry and windy weather — recognized as HDW occasions — inflicted essentially the most harm on harvests.
Ok-State agronomy professor Stephen Welch ran the research’s theoretical modeling that confirmed how varied climate situations impression plant progress. The compound impression of these three extremes occurring collectively, he stated, is considerably better than after they happen one at a time. And within the Great Plains, these HDW occasions are ramping up.
“That precise combination of events has been increasing over the 40-year period due to climate change,” Welch stated. “That’s a key factor.”
Here’s what the research discovered:
For each 10-hour interval that a wheat subject experiences a scorching, dry, windy occasion, the quantity of grain it will definitely produces goes down by 4%.
That’s particularly tied to when HDW occasions occur throughout the important latter phases of the plant’s progress. In Kansas, wheat typically hits that point of flowering and ripening throughout the spring.
Unfortunately, that’s additionally the time when Kansas winds are inclined to whip the fiercest. On common, April is the windiest month of the 12 months in Kansas. And the gusts blew particularly laborious final 12 months. Goodland and Salina skilled their windiest April on document.
The variety of HDW weather occasions considerably elevated throughout the research’s information interval from 1982-2022 as greenhouse fuel emissions warmed the climate.
And the locations that noticed the sharpest rise within the frequency and severity of those occasions had been the identical ones that endured the Dust Bowl almost a century in the past, together with western Kansas. The southern High Plains is already the windiest region within the inland U.S. and one of the driest regions east of the Rockies based mostly on historic averages. So it is sensible that small, incremental modifications in climate can be felt acutely right here.
Kansas State University professor and state climatologist Xiaomao Lin, who led the analysis workforce, stated the research expects these HDW occasions to grow to be much more frequent, intense and protracted as climate change continues over the subsequent 25 to 75 years.
“In terms of a projection,” Lin stated, “we can see that increase will continue … especially without any mitigating of greenhouse gas emissions.”
Another new report, from the American Meteorological Society, corroborates these findings. It reveals how warming global temperatures have pushed a rise in excessive droughts around the globe in recent times and made beforehand unprecedented warmth waves extra commonplace.
The enhance in HDW occasions within the Great Plains shares a robust connection to what’s occurring within the Pacific Ocean.
The research established a link between situations of scorching, dry, windy weather right here and the cycles of the Pacific Decadal Oscillation, which the National Oceanic and Atmospheric Administration describes as a “long-lived El Niño-like pattern” of shifts within the Pacific Ocean’s temperature.
Beginning to know that connection, Lin stated, may assist predict the dangers wheat crops face over the long-term future as these Pacific temperatures ebb and stream.
The finest likelihood
The research’s findings, Lin stated, enhance the strain to develop new wheat seed varieties that may higher face up to this particular mixture of scorching, dry and windy situations. And to ship instruments that assist farmers know when to count on HDW occasions and what to do when their subject will get hit with one.
“We cannot do too much (about the weather),” Lin stated, “but we have to inform the farmers.”
For now, Kansas wheat growers need to hope the seeds they planted final fall can dangle on to see the drought break by spring.
Tanner, the northwest Kansas farmer, harvested simply sufficient wheat final 12 months to get by financially and make it to a different season. But when that subsequent season got here, the situations didn’t get any higher.

Drought has solely tightened its grip throughout western Kansas, and the soil has just about no moisture left. Tanner ended up planting most of his wheat seed into fields that had been nonetheless lined with useless crops from final fall’s failed corn and soybean crops. At the very least, these scraggly leftovers may assist hold the grime from blowing away.
About a third of the wheat he planted hasn’t sprouted in any respect but. Just seeds sitting within the parched earth. But as his fields inch someday nearer to eventual rains, he’s optimistic that these late bloomers often is the fortunate ones.
“Frankly, that might wind up being our best chance for production,” Tanner stated, “because it hasn’t had a chance to die yet.”
