Soil moisture - capacitance (5TE Decagon)

Parameter to be measured:

Soil moisture, soil temperature, EC

Method:

Capacitance

Equipment:

• 5TE Decagon

Advantages:

• Relatively cheap
• Easy to install
• Compatible with many loggers

Disadvantages:

• Calibration needed
• Small measurement volume compared to other sensors

What to watch out for:

• Careful installation, air gaps have a sustainable influence on the measurement compared to other sensors because of the small measurement volume
• Probe is tenderly and will break, if it is pushed in resistive media.
