Bow startup invents high-tech fix for farmers' irrigation problems

BOW — After growing up on a potato farm in Bow, David and Connor Wallace went on to study sciences in college and then work at technology companies in Seattle and California’s Silicon Valley.

“The entire time I was feeling drawn back to the farm and agriculture, and applying technical skills to problems in agriculture,” David Wallace said.

In 2019, David Wallace quit his job as a data scientist for Amazon and started working full time on his family’s farm, Wallace Farms. His dad told him about a problem with his irrigation equipment that damaged crops and wasted water and fuel.

David Wallace teamed up with younger brother Connor, who had spent six years working as a web and software developer in Silicon Valley, to find a solution.

The result was CODA Farm Technologies, a company the brothers started in their parents’ garage in Bow.

They invented FarmHQ, a small cellular-connected device that attaches to farmers’ existing irrigation equipment.

The technology enables communication between different pieces of equipment, helping farmers prevent crop loss and water waste. It also allows farmers to monitor their irrigation remotely from a smartphone or computer.

Since CODA Farm Technologies’ founding in 2020, hardware engineer Gabe Martin and software engineer Dan Oschrin have joined the team. The company has sold nearly 100 FarmHQ devices to farms in the U.S. and Canada.

More control for farmers

Many Skagit farmers use traveling irrigation reels that pull sprinklers across fields to water crops. David Wallace said the reels occasionally malfunction and stop with no warning, while the pumps supplying the water keep running.

The result is that a sprinkler — which can pump 300 gallons a minute — will sit in a single spot and flood a section of a field.

“It can have a drastic impact on fields,” David Wallace said. “It erodes the hills and starves potatoes for oxygen. (My dad) had a really simple request of us: figure out how to automatically shut down the pump when the reel stops.”

David Wallace said the brothers searched for existing technology but found nothing.

“We decided to build our own,” he said.

Working out of their parents’ garage, the brothers built 10 prototypes and tested them on potato farming equipment. They had a working device by the end of summer 2019.

The FarmHQ technology includes three parts: cellular-connected boxes that attach to irrigation reels and pumps, magnetic sensors and a mobile phone app. The company also sells a solar and battery kit to power the device.

Farmers receive a mobile alert when an error occurs with their irrigation reels and their pump is automatically turned off.

When a reel malfunctions and stops retracting, the device sends a signal to the pump to shut down. Farmers receive a mobile alert that an error has occurred and that the pump was automatically turned off.

Without the technology, a farmer would have to drive out to a field to check if equipment was functioning properly.

Connor Wallace said during his time working in the Silicon Valley, he was impressed by technology, but found that some companies were trying to solve problems that nobody had.

“Coming back to the Skagit Valley, there are so many problems we can solve here to make people’s lives better,” he said. “Turning off a pump for a farmer so he doesn’t have to go out at 6 a.m. (to check).”

Farms utilizing the technology include growers of potatoes, Brussels sprouts, broccoli, spinach and chard seed, berries, pasture hay and sod, including eight Skagit Valley farms.

“Word of mouth has been really big for us,” Connor Wallace said. “It’s been cool to see how excited farmers are about the product.”

Vegetable seed grower Sean Galbreath of Burlington was one of the company’s first customers. He said the FarmHQ device saved crops last season after the farm’s irrigation reels experienced problems.

He said the device also helps the farm avoid wasting water and fuel.

“It pays for itself pretty quickly,” Galbreath said.

During the 2020 growing season, FarmHQ devices saved 243,000 gallons of water per reel, CODA Farm Technologies states on its website. The devices saved 45 gallons of fuel for each diesel-powered pump, equivalent to about 1,000 pounds of carbon dioxide.

The technology allows farmers to access real-time information about their irrigation on a mobile dashboard. 

The company’s mobile phone app allows farmers to access real-time updates about their equipment.

Galbreath said in the past, he had to drive out or send an employee to a field to check on equipment. With a small crew and farm fields scattered throughout the Skagit Valley, that gets tricky.

”(Now) we can look on our phone and go ‘everything is OK with our irrigation,’” he said.

Bringing technology to agriculture

High-tech has already arrived in farming, from self-steering tractors and drones to robotic planters and weeders.

Connor Wallace said the technology sector could do more to serve farmers, and CODA Farm Technologies hopes to use its product to do so.

“One other really exciting thing about this technology is it’s applicable for other uses, not just for irrigation,” he said. “So many things (in farming) are sending a person out to a field to look at a gauge or to turn on a pump.”

Connor Wallace said the device also estimates water use, allowing farmers to look back and see where they are using too much or too little.

”This provides someone the ability to know and apply the right amount,” he said.

David Wallace explains how magnetic sensors (silver strips) monitor an irrigation reel. The FarmHQ device mounted to the reel transmits the data to farmers via a cellular network.

The Northwest Innovation Resource Center, a Bellingham nonprofit that works with entrepreneurs and early-stage startups in five counties, provided assistance and mentorship to CODA Farm Technologies as it was getting off the ground.

Diane Kamionka, the center’s executive director, said a key for the company is that its product works with farmers’ existing irrigation systems.

”It’s old technology, but adding some new technology in an efficient way that is very workable and easy for people to understand,” she said.

Kamionka said the center is planning a new program this fall for a dozen aspiring ag-tech startups.

“We believe entrepreneurial activity, especially one using new technology like (CODA Farm Technologies) is very critical to the economic vitality of the region,” she said.

David Wallace said the company’s goal this summer is to sell 300 FarmHQ devices.

”When we achieve that, we will have a nice profit,” he said.

Both brothers said it’s rewarding to work on a project with immediate impact.

“The feeling is satisfying ... It’s about as rewarding as it gets with technology,” said Connor Wallace.
