The Stevens Tempe Cell System can employ five different methods to eliminate the uncertainties from soil moisture measurements and achieve the highest level of accuracy. This system uses an enhanced gravimetric method to measure soil moisture to obtain the actual volumetric water content and develop a soil moisture calibration equation to validate and/or program into soil moisture sensors. In addition, the system’s outputted data can be used to develop a soil-specific calibration curve, and to develop an algorithm to determine the soil’s matric potential using the HydraProbe.
The Stevens Tempe Cell is ideal for mesonets, climate reference networks, and soil monitoring stations.
- Provide a traditional gravimetric method for determining soil water content.
- Determination of bulk density, porosity and saturation of soil.
- Develop soil-specific calibration equations to adjust and/or validate soil moisture sensors using an enhanced gravimetric/volumetric soil moisture determination.
- The system’s volumetric water content data output can be used to develop a soil-specific calibration curve*
- A soil-water retention curve up to 2 bar can be developed and curve-fit to the output of HydraProbe sensors enabling the HydraProbe to output matric potential for specific soils.*
* Advanced soil retention curve development option required.
- Agriculture/agricultural research
- Climate reference monitoring
