Moisture thresholds help you visualize the drought status of your soils in real time, so you can better manage your irrigation and preserve your water resources.
What are moisture thresholds?
To help irrigators interpret their probe data, Weenat has developed its own Decision Support Tool (DST): the Moisture Thresholds.
Based on the measurements from your Capacitive or Tensiometric Probe, this tool determines whether your plants have enough water or are beginning to experience water stress. Once water stress is reached, it is often too late to intervene effectively.
Understanding and using the moisture threshold graph
The moisture threshold graph is divided into four color-coded zones, each representing a soil moisture level to help guide your irrigation decisions at a glance:
🔵 Saturation: The soil is saturated. No need to irrigate, wait for the curve to drop.
🟢 Comfort: Soil moisture is optimal for the crop. Try to keep the curve in this zone.
🟠 Warning: The plant is starting to lack water. Irrigation may be needed, unless significant rainfall is forecast.
🔴 Water stress: The water deficit is too high. It’s often too late to act effectively—it's better to intervene while in the orange zone.
You can track the evolution of water availability in your soil, also taking into account rainfall and water inputs displayed in the graph.
Water inputs shown on the graph must be added manually by you in the Weenat app.
Adapted and customizable thresholds
Weenat provides predefined thresholds for the main soil types to suit most situations.
Good to know: you can set up multiple sets of soil moisture thresholds, tailored to each crop, soil type, or plot.
How to modify my soil type
Need more precision? You can customize these thresholds directly from the app, based on rooting depth, soil type, or your crops' specific needs.
On your plot, go to the "Soil texture" tab, accessible via the gear icon at the top right of the screen.
From this section, you can modify your soil composition by adjusting the percentages of clay, sand, and silt.⚠️ Note:
The system does not necessarily retain the exact values entered, but instead calculates an average percentage corresponding to the closest soil type based on the entered parameters.
This setup does not take into account the organic matter content or coarse elements in the soil.Need more precision? You can customize these thresholds directly from the app, based on rooting depth, soil type, or your crops' specific needs.
