Campbell Scientific EasyAG Probe for Soil Volumetric Water Content Profiles - Manual (Page 26)

Appendix B. Tube Installation
Small air gaps of 1 – 2 mm between the soil and the access tube near the
surface may be closed with light finger pressure without causing major errors
in the soil moisture detection.
A significant air gap of greater than 2 mm between the soil and the access tube
near the surface may be corrected by carefully pushing a spade into the soil
adjacent to the probe and gently levering the soil against the tube. The spade
should be at least 15 cm away from the access tube when this is done to limit
any error in the soil moisture detection. The installation should be re-done at
another site if correction of air gaps is not progressing well.
