2. Installing the EA-10

The EA-10 monitors the water content of the soil in

which it is placed by measuring the dielectric constant

of the soil and water surrounding the probe. While the

probe measures just the soil which is adjacent to it, its

reading is most useful if that measurement represents

the general soil conditions in which the probe is

placed. For that to happen, the monitoring site must

be carefully sel-ected, and the probe must be properly

installed.

Procedure

When installing the ECH

mize contact between the probe and the soil. There

are two methods to accomplish this.

1. Use Decagon's Probe Installation Kit to install the

probe. This kit has a custom-shaped blade to make

the insertion in the soil, then another tool to place

the probe into the insertion. For deeper installa-

tions, use an augur to reach the desired depth,

then use the Installation kit with extension rods to

install the probe.

2. Use a thin implement like a trenching shovel, gar-

dening spade, or flat bar to make a pilot hole in the

soil. Then insert the probe into the hole, making

sure the entire length of the probe is covered.

Finally, insert the shovel again into the soil a few

inches away from the probe, and gently force soil

toward the probe to provide good contact
