Jump to navigation
Jump to search
Parameter to be measured:
Soil moisture
Method:
Trime TDR-method
Equipment:
- IMKO: T3 tube probe
Advantages:
- easy and fast measurement in access tube to the depth of the access tube
- manual measurements
- accuracy comparable to neutron probes
Disadvantages:
- installation of access tube in gravel rich soils is complicated
What to watch out for:
- The measurement volume of the probe is not circularly around the probe. To measure the mean water content of one profile representative requires measurement in different directions.
