Soil Type (first menu)
Displays a choice of sensors for associating with a soil type in the next sub-menu.
Options : All Sensors, Sensor 1, Sensor 2,........Sensor 6 Default: All Sensors
Each sensor in a Profile Probe can have a different soil type associated with it. You
may choose to set all sensors to the same soil, or individually set each one.
Select
Options, Soil Type and select a particular sensor or All Sensors, to open the
second level Soil Type menu.
Note: Sensor 1 denotes the first sensor nearest the surface, usually at 100 mm.
Sensor 4 is at 400 mm.
In a PR2/6 the lowest sensor is Sensor 6 at 1000 mm.
Soil Type (sub-menu)
Displays a choice of soil types to associate with the previously selected sensor(s).
Options: Organic, Mineral, Soil 1, Soil 2......Soil 5. Default: Mineral
Two soil types are always available,
Mineral and Organic.
You may also define five more via Soil Set-Up on the Options menu.
Having selected a sensor or all sensors under Options, Soil Type, now select a soil.
Example: To set all sensors to Organic
Select Options, Soil Type, All Sensors, Organic
This will set all sensors in the Profile Probe to use the default Organic soil parameters
a0 and a1.
Soil Set-Up (first menu)
Displays a choice of soil types for defining soil parameters.
Options: Organic, Mineral, Soil 1, Soil 2......Soil 5. Default: Mineral
Soil Set-Up is used to define empirical soil parameters a0 & a1 used to convert the
measured bulk permittivity into moisture content readings.
Soil Set-Up is also used to define field water capacity, needed if you want moisture
deficit readings.
Beginners can skip this section by choosing the Mineral or Organic under Options ,
Soil Type and by not asking for mm Deficit in the Options, Display menu.
