Background articles about measuring trees and irrigating green roofs: growth, water stress and smart watering — the knowledge behind PlantData.Live.
What is a dendrometer?
How a dendrometer measures growth, daily shrinkage and water deficit — and how you recognise water stress days in advance.
What is vapour pressure deficit (VPD)?
What VPD is, how it is calculated and why it is the driver behind a tree's water stress.
Is your soil moisture sensor still measuring correctly?
Why a slowly drifting sensor is more dangerous than one that fails — and how to read its reliability from the measurement data itself.
Start-up procedure for controlled green roof irrigation
Calibrate a soil-moisture-controlled irrigation step by step: moisture threshold, timing and cycle duration — with a practical example.
