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 as well as continuously logged measurements possible, but if logged measurement only in one depth
- accuracy comparable to neutron probes
Disadvantages:
- installation of access tube in gravel rich soils is complicated and the IMKO drill is useless in this soils.
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.
Problems/Questions:
