Farming in the Pacific Northwest’s Yakima Valley offers a study in extreme contrasts. On one hand, the volcanic soil and desert climate create an agronomic powerhouse capable of staggering crop yields. On the other hand, the region presents some of the most punishing regulatory, environmental and economic headwinds in U.S. agriculture.
For Jason Sheehan, managing partner of J&K Dairy in Sunnyside, Wash., surviving — and thriving — in this environment requires relentless diversification, a deep commitment to resource management and a willingness to run counter to industry trends.
“When everybody else goes right, I look a little different. I go left,” Sheehan says.
Alongside his wife, Karen, Sheehan oversees a diversified enterprise that includes 3,000 milking cows, over 2,000 acres of forage and row crops, and an expanding (if sometimes begrudging) footprint in tree fruit and wine grapes. But getting to this scale wasn’t an overnight endeavor; it is the culmination of bold risks, family integration and a healthy dose of pioneer grit.
The Foundation
The roots of J&K Dairy trace back to California, where Karen’s parents, Tony and Brenda Vega, decided the adrenaline rush of Tony’s six-year career as a police officer was too much. Believing there was no better place to raise a family than a farm, they sold everything they owned in 1978 to buy 200 cows. By 1981, they moved the herd to Washington State.
Sheehan, a Minnesota native who swore he’d never leave the Midwest, eventually found his way to California, met Karen and relocated to Washington 24 years ago to join the family business. In 2003, they officially launched J&K Dairy by purchasing a neighbor’s 419-cow herd. By 2012, they had merged their operation with Tony and Brenda’s dairy, creating a single, integrated powerhouse.
Today, J&K Dairy milks 3,000 cows three times a day across two facilities. But reaching optimal operational flow required some trial and error. The farm previously expanded to 3,800 cows, milking them 2.5 times a day, but Sheehan found the schedule taxing.
“It was actually harder on the people than it was on the cows,” he admits.
They recently scaled back to 3,000 cows, migrating the milking herd at the main dairy site entirely into freestall barns to better protect them from the region’s harsh summer heat and winter weather.
Going Left: Uteruses and Beef-on-Dairy
One of Sheehan’s most contrarian strategies lies in his herd replacement philosophy. While many dairies are aggressively cutting heifer inventories to save costs, Sheehan views surplus heifers as a critical safety net and revenue driver, particularly to fuel his beef-on-dairy program.
“I believe in more uteruses,” Sheehan says.
To maximize the beef-on-dairy premium — which he estimates adds $5 per hundredweight to their bottom line — a dairy must first ensure its internal heifer pipeline is completely secure.
“If you are short on heifers coming in, you can’t turn over your cows. Then you’re missing not only your check from your day-old beef calves, but you’re missing your check from being able to cull your cows and turn that herd over,” he says.
Drought and Agronomy
“I tell people that my job is a dairyman and my hobby is a farmer,” Sheehan jokes.
But managing 2,000 acres of corn, triticale and alfalfa in a desert requires serious agronomic expertise, especially considering the farm is currently weathering its fourth consecutive year of drought. The farm relies entirely on irrigation, drawing from the Roza Irrigation District, a junior water rights holder. This year, the district is only allocating 52% of its normal water supply, cutting Sheehan’s farm from 36" of water down to just 19".
To survive, J&K Dairy has transitioned from a single 40-acre center pivot to 36 center pivots controlled via smartphone. Using soil sensors, satellite crop imagery and aggressive no-till and strip-till practices, the farm has revolutionized its water efficiency. Historically, the farm used 42" of water with furrow irrigation to grow a single crop of corn silage yielding 25 to 30 tons per acre. Today, using just 24" of water, they double-crop corn and triticale to yield well over 50 tons per acre combined.
Water conservation is also a political necessity. The dairy operates under strict CAFO permits and faces intense scrutiny over groundwater nitrates. However, the region has also fostered incredible collaboration. Sheehan pointed to the Yakima Integrated Plan, a landmark initiative where Native American tribes, environmentalists and farmers negotiated water management together to protect salmon runs while preserving agricultural irrigation — keeping the fight out of the courtrooms.
The Brutal Realities of Washington Labor
Despite these agronomic successes, the financial reality of farming in Washington State is sobering. According to USDA data, Washington ranked last in the nation for net farm profitability recently, posting a total net farm loss of over $400 million.
A primary driver of this is the state’s labor environment. Washington boasts the highest agricultural labor costs in the country, anchored by a $17.13 minimum wage and a Nov. 5, 2020 State Supreme Court ruling that forced dairies to pay overtime for anything over 40 hours a week — a change implemented virtually overnight.
“One thing about farms — it’s hard to get anything done in 40 hours,” Sheehan notes.
These labor costs severely impact J&K Dairy’s diversification efforts. The farm manages 100 acres of wine grapes, 45 acres of cherries and recently acquired 135 acres of apples. Why apples? Sheehan bought the orchard simply because he needed the land to lay a pipeline to pump liquid manure to his other fields.
But harvesting tree fruit is labor-intensive, and the economics are currently upside-down.
“We just got done picking cherries today, and the last two years, the cost of the labor to pick the cherries has been higher than our gross returns on the cherries,” he shares.
Capital Squeeze and The Long Play
Beyond labor, J&K Dairy is navigating a massive capital squeeze on the milk processing side. As member-owners of Darigold, the farm is helping finance a massive new butter and powder processing facility in Pasco, Wash.
To fund the build, cooperative members endured a crushing $4 per hundredweight deduct on their milk checks last year, which has since been reduced to $2 per hundredweight. It has effectively erased on-farm profitability.
“People ask me, ‘What are you doing on your dairy?’ And I tell them, ‘Well, we’re building a processing plant,’” Sheehan jokes. “Most of our profits and capital right now are going into our processing plant, which I think is a really good long-term play. It’s just really miserable short term.”
Preserve the Future
Through drought, regulation and margin squeezes, Sheehan remains deeply committed to his team of 43 employees and to the future of the farm.
With four children — Jared, Claire, Andrew and Annelise — the next generation is already heavily involved in 4-H, FFA and farm operations. But Sheehan and his wife have instituted a strict succession rule: The kids are welcome to return to the farm, but only after they turn 25 and have worked for someone else first.
As J&K Dairy looks to the future, the strategy remains clear. They will match their acres to their cows, protect their water, invest in their people and continue to weather the short-term storms. Because in the Yakima Valley, resilience isn’t just an asset — it’s a requirement for survival.
