A note about soil electrical conductivity outputs. Saturation extract EC and Pore Water EC are models that result in fair accuracy (+/- 20%) in soils with high water content (above 25% VWC). Use of either of these model outputs is not recommended when soil water content is below 15% VWC. When water content is low use Bulk EC instead.
Bulk EC is the electrical conductivity of the bulk soil (soil, water, and air). Saturation extract EC tells exactly how much salt is in the soil. Pore Water EC is the electrical conductivity of the water in the soil pores. For more information visit our complete guide on soil electrical conductivity.
Measurement unit preferences are per user.

Some measurement categories allow you to choose between different types of representations of the same underlying data. In these cases, only one parameter type can be displayed at a time within that category.

This means that when you select one option, the others in that category will not be shown simultaneously.

Water Content

The Water Content category supports multiple ways to represent soil moisture, but only one can be active at a time:

  • Volumetric Water Content
    • m³/m³
    • % (percentage)
  • IPF (inches per foot)
  • Raw sensor output

You cannot display both processed values (e.g., % or m³/m³) and raw sensor output at the same time. Devcie downloads will however, contain Raw sensor output either as an additional tab or a separate file.

Humidity / Vapor Pressure

The Humidity / Vapor Pressure category provides different ways to represent atmospheric moisture conditions:

  • Vapor pressure
  • Humidity
    • RH Relative Humidity
    • % RH (Percent Relative Humidity)
  • Water activity

Soil & Media Electrical Conductivity

The Soil & Media Electrical Conductivity category includes multiple interpretations of conductivity depending on the measurement method:

  • Saturation Extract EC mS/cm
  • Pore Water EC mS/cm
  • Bulk EC mS/cm
