Soil EC and salinity sensors
What is a soil ec and salinity sensors?
Soil EC sensors measure electrical conductivity as an indicator of salinity, often in the same probe as moisture. They help manage leaching on saline water or soils, but bulk EC is not pore-water EC or a nutrient test and needs interpretation.
Premium collection: Root-zone salinity data to steer drain and leaching. Criteria met: Closed-loop control, Measured resource efficiency.

| Bulk EC range (example) | 0–20 dS/m |
|---|---|
| Accuracy (example) | about ±(5% + 0.01 dS/m) below 10 dS/m; about ±8% from 10–20 dS/m |
Typical applications: Salinity and leaching management, fertigated crops.

Advantages
- Continuous salinity trend
- Often combined with moisture sensing
- Supports leaching decisions
Limitations and risks
- Bulk EC differs from pore-water and saturation-extract EC
- Does not measure individual nutrients
- Contact and temperature affect readings
Maintenance
- Check soil contact
- Confirm temperature compensation
- Compare with lab extracts periodically
Sustainability and compliance
Supports salinity control where irrigation water is marginal.
Ask which EC the sensor reports and the conversion assumptions used.
Questions to ask in your RFQ
- Which EC does the device report?
- How will readings be compared with lab tests?
- Is temperature compensation built in?
Components it depends on and projects that use it
Used in project kits: Greenhouse vegetables on substrate
