How is soil moisture measured by SoilQuality?

SoilQuality moisture measurement is given in Absolute Volume Ratio (AVR), which is the ratio between the volume of water divided by total volume of Soil + Water after mixing both.


At 70% AVR moisture the soil becomes extremely close to a liquid and not adequate for plants growing in soil. Therefore, SoilQuality has been designed with full scale at 70% and provides AVR Soil Moisture measurement between 0 to 70%; above 70%, the reading will remain at 70%.

‘Soil Sensing Probe’ should be gently cleaned with disinfectant alcohol if moisture reading doesn’t reach 70% in water.
