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“.
Why does the POGO have 4 metal tines? Read More »
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.
I only have roots that are 1” deep. Don’t I want to measure to a depth of 1”? Read More »
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.
Can I replace the tines on the POGO? Read More »
Using the patented and unique Stevens HydraProbe II sensor and its coaxial impedance dielectric reflectometry protocol, POGO measures WFV (aka VWC) and EC to an accuracy of ±1% without any calibration in any soil. Surface heat index and soil temperature are measured with Infrared and a soil temp probe respectively with equal precision. It does
How does the sensor in the POGO differ from other sensors? Read More »
No, pH is a measurement in solution. Soil consists of solution, air and particles.
Can pH be measured with the sensor in the soil? Read More »
