Davis, CA – February 8, 2021 Nearly a year after launching Tule Vision, Tule’s latest offering has become even more beneficial in helping growers make informed decisions about irrigating their vineyards. Leaf potential measurements are displayed in real time on the Tule Vision dashboard.

Growers can use Tule Vision to measure the water potential of their vines in the afternoon by simply recording short video clips with an iPhone. The photos from each video are then sent to the model, which relays the readings in real time to the grower’s phone. Pore pressure data and photos are also displayed in the Tule web application.

“With Tule Vision, we can take fast and accurate water stress measurements without special training or cumbersome equipment. This allows us to easily create weekly irrigation schedules,” says Chris Storm, vineyard manager at Wine Farms. “My advice to anyone considering using Tule Vision is: try it, be humble, learn from the technology and let it help you become a better irrigator.” Using the Tooele Vision block, growers can see where the leaf water potential measurement took place, as well as view current photos of their vines.

In 2014, Tule launched Tule Sensors, a research product from UC Davis that uses field sensors to measure actual evapotranspiration (ETa) and water stress in the vineyard. The sensors are also connected to the vineyard’s irrigation system to measure the amount of water used. The combined data is used to make irrigation recommendations that maintain exactly the level of stress in the vineyard that the winemaker prefers. Using thousands of water stress measurements from Tule’s sensors and photos taken by field technicians, Tule was able to develop an artificial intelligence model that feeds Tule Vision.

For producers who rely on pressure chamber measurements, Tule Vision makes it easy to take more measurements in less time. For vineyard managers less familiar with pressure chambers, Tule Vision provides a simple, quick and cost-effective way to take mid-day waterleaf measurements that indicate water stress in the vineyard. With an unlimited number of users, anyone working in a vineyard organization can take measurements and access this information to get a more complete picture of vineyard health. Tule Vision users simply point their iPhone at the canopy and record a short video. Tule Vision then reports the water potential of the leaves in real time.

“Since the initial launch of Tule Vision, we have received a lot of feedback from users, which has allowed us to refine the model and provide farmers with an even better experience,” says Tom Shapland, PhD, founder and CEO of Tule.

One change producers will notice this season is a feature that teaches users to record the video that works best in Tule Vision’s artificial intelligence model. By informing users in real time how to position themselves near the canopy, this enhanced feature will allow for more accurate measurement of the water potential of Tule Vision’s leaves. Tule is also currently developing a beta feature that will allow users to attach their iPhone to their ATV and passively collect measurements as they drive along rows of vines.

“Helping farmers meet their production goals is at the heart of what we do,” says Shapland. “We rely heavily on relationships with our customers and are always looking for new ways to improve our offerings to them.

About Tula Technologies

Tule helps farmers make irrigation decisions. Tule (pronounced “too-lee”), founded in 2014, combines the use of state-of-the-art artificial intelligence with agronomic expertise in the field to provide farmers with the information they need to make optimal irrigation decisions to meet their production goals. UC Davis’ research-based Tule sensors provide farmers with measurements of crop water use, water stress, applied irrigation and irrigation recommendations. With their new A.I. product, Tule Vision, growers can monitor their vines via video and determine the water potential of leaves in the middle of the day.
