Your browser does not support the video tag. In the time-lapse video, we can clearly see how a lemon tree wilts due to a lack of water and then perks back up after being watered. The time-lapse is not only beautiful to watch, but also serves as part of a series of experiments. The tree is equipped with sensors. This allows us to observe the relationship between what we […]

Have you ever wondered: How closely am I related to the Norway maple? Follow the two colored lines (human: purple, Norway maple: red) on the interactive tree and find out. Oak, linden, elm, and maple are just a few of the tree species we’re familiar with in our daily lives. But how exactly are these trees actually […]

Prerequisites: TreeSense Pulse: Electrical Resistance Measurement Explained A brief recap of resistance measurement in the Pulse Sensor Electrical resistance (measured between two conductive screws in the xylem) is a strong indicator of moisture content in the branch. Simply put: dry wood has high resistance, while moist wood has low resistance. However, resistance is also influenced by temperature and tree species-specific […]

The retention curve illustrates the relationship between water content and soil water tension. This relationship is characteristic of each soil type and is influenced by various factors. One of the most important factors is the pore size distribution. This is closely related to the soil type, which is why it is common to specify typical retention curves for different soil types. The figure shows retention curves for sand, silt [...]
