Sap flow sensors have been largely abandoned because of technical challenges and the availability of simpler indirect measures for measuring a crop's water status. These indirect measures are easier to use, but they do not provide a direct measure of a crop's water use. We have developed a novel sensor technology that is a game-changer in the precision irrigation market, offering unparalleled accuracy, simplicity, and reliability in measuring actual crop water consumption.
Our sensor uses a novel heat dissipation model to measure the movement of water (sap flow) within the sapwood (xylem) of trees through the process of evapotranspiration (ET). The distortion of the heat field generated around the sensor probe is directly related to the velocity of water movement, which is then converted to the volume of water used by the tree using the sapwood area. This enables us to accurately measure the actual water use of trees and gain valuable insights into their physiological processes.
Locating the optimal spot to place the sensor on a tree can be challenging, like trying to locate a needle in a haystack. To overcome this challenge, we developed a robust water balance algorithm that accounts for any potential variability due to environmental conditions and biological factors. This allows us to confidently place the sensor almost anywhere on the tree and accurately determine the amount of water transported within the tree's sapwood (xylem). Our solution has been shown to achieve 90% accuracy, ensuring reliable and consistent results.
The SaaS (Software as a Service) irrigation management platform is unique in that it combines unprecedented accuracy of crops’ actual water needs and through Treetoscope’s AI-driven engine, integrates this with soil, satellite and real-time weather data. Together, the solution provides growers with irrigation insights, stress level management, weather history and forecast, plot level suggestions and 24/7 alerts and notifications.contact us
