It’s a uniquely patented design that maximizes sampling size and precision while utilizing a unique, scientifically precise and accurate measurement method called “Coaxial Impedance Dielectric Reflectometry“.
Even if roots are very shallow (1”), due to natural capillary activity in a turfgrass root zone, this shallow root system is still predominantly influenced by the top 2 to 2.5” of the root zone medium.
Even in deep-rooted systems, the predominant exchange of moisture and salinity that the turfgrass depends on for optimal performance occurs in the top 2 to 2.5”. This is always the region you want to measure and reference against over time. By varying the depth, you will end up basing your decisions off of invalid information. …
No! The predominant moisture and salinity exchange with the root system of all types of turf occurs in t the top 2” to 2.5” of the root system. This is why POGO was designed to measure the top 2.2” inches for moisture and salinity. When the sensor is measuring too deep, you are diluting the …
If the tines get damaged, the entire integrated sensor assembly can be replaced as one unit.
The tines integrated with the sensor have a 2 year warranty. The tines are made of very high marine grade stainless steel built to last through years of use in all turf/soil types.
Using the patented and unique Stevens HydraProbe sensor and its coaxial impedance dielectric reflectometry protocol, the POGO measures WFV and EC to an accuracy of ±1% without any calibration in any soil. Visit soilsensor.com to learn more about various measurement methods.
No, pH is a measurement in solution. Soil consists of solution, air and particles.
