It will only get worse for the next generation as the aquafers are continuing to be depleted.
Is anyone actually irrigating wheat?? Edit: I'm being downvoted because someone found a source that says 3% of winter wheat in Montana is irrigated. My point still stands, while yes some percentage of wheat is irrigated it is extremely uncommon.
> Leonard’s operation near Goodland is a diversified operation with a mix of dryland and irrigated acres in addition to a small cow-calf operation. Encouraged by his PlainsGold seed rep, he entered the yield contest for the first time in 2022. His entry came from a field planted to certified seed wheat that followed pinto beans, which provided some moisture profile.
> “Our soil will hold about 1.8 inches of moisture per foot,” Leonard said. “So, if we have six feet of subsoil, we have some gas in the tank. We had some of that last year, but we don’t have that this year.”
> From planting until harvest, the field only received 6.2 inches of moisture, so Leonard pumped another 10 inches of water to help the wheat crop along. He also furtigated nitrogen through the pivot to further boost yields. The widespread drought conditions last growing season meant it was too dry for even the weeds to grow, so he did not apply any fungicide.

> The four major grain crops grown in Kansas (corn, soybean, grain sorghum and wheat) have experienced upward trends in yield (Figures 7 – 10). Corn yield has had the most dramatic increase for both irrigated and dryland production with irrigated corn yield improvements of approximately 2.5 bushels/acre for the each year of record, This result is more than twice the dryland rate of 1.1 bushels/acre. The average irrigated yield increase is 0.59 bu/ac, 0.60 bu/ac and 0.31 bu/ac for soybean, grain sorghum and wheat respectfully. Irrigated yield increase trends have been larger than for dryland.
Page 8 figure 10 shows the yield trends for wheat - both irrigated and dryland since 1974.
