cause the sensor board is flexi-
ble, care should be taken to
avoid snapping it during instal-
lation. To limit the effect of
water
moving
vertically
through the soil profile, the
sensors should be installed so
the flat face is perpendicular to
the soil surface. For the same
reason, if sensors are installed at multiple depths, they
should be offset from one another.
Removal
Care should be taken when removing a sensor that is firm-
ly embedded in soil. Pull on the molding only. Pulling on
the cable risks damaging the wiring.
Suggestions for protecting sensor cables from rodent
s
-
For vertical installations, run sensor cables through PVC
pipe. This can be the same tube used as an installation
tool.
-
For sensor cable that will be running parallel to the
ground, either above or below the soil surface, the sensor
cable can be fed through flexible conduit or drip irrigation
tubing. When using drip irrigation tubing, it is preferable
to use used tubing. This is because the tubing will have
the curl taken out of it and will be easier to keep straight.
A slit should be cut into the tubing with a box cutter and
the cable pushed inside. If the cable and protective cover
are not buried, they can be secured to the ground wire
with hooks or turf staples.
