Sorry, there are currrently no FAQs regarding the AUGER - PR2 Installation

UG-SP1   Stabilisation Plate (with stakes) ensures that the augered hole does not become misshapen at the top (a cone shape) which results in a gap between the soil and the access tube.  You can install access tubes without this but would need to exercise great care and it is almost certain that the hole made will not be perfect

PR-AUG1  Pilot Auger makes a hole around 23mm diameter. This is a standard gouge auger that we have modified so that it fits inside the stabilisation plate. If you have a good quality gouge auger, this will help, but the hole may still be the wrong diameter. An auger for around 26mm is needed and even then the hole might not be perfect

DBM-1  Mallet contains lead that helps with hammering the auger and access tube. An alternative  could be used, but a dead blow makes the installation of many access tubes a little easier

PR-AUG4  removes just a few mm of soil from the augered hole to create a smooth wall that allows for close contact between soil and access tube. If you use only a gouge auger, then measurements may be compromised

AT-ROD1   Insertion rod. This is really vital and you can not avoid this item. Once you have a hole augered you place this rod into an access tube and hammer the rod + tube down the hole. You can not hammer the access tube directly – it will shatter or crack

AT-CR1  Cleaning rod is useful but you could make your own. It is needed to remove water from inside the tube before you insert the PR2 for measuring. Where does this water come from?  The rubber caps can perish in UV and crack, allowing rain inside. The caps are not airtight. Moisture in warm air can enter the access tube and start to cool. The temperature difference inside the tube at 1cm and 100cm can be significant. The moist air may condense deep inside the tube and water will then form in the base of the tube.
Inserting the PR2 into water may lead to damage of the probe so it is advisable to check for the presence of water and remove it.

FLX-1   Flexi canes have a plastic marker flag so that you can find the access tube, even when the crop height has increased
