FAQ

What is the Pressure Potential?
Pressure Potential is energy per unit volume of water required to transfer an infinitesimal quantity of water from a reference pool of water at the elevation of the soil. Pressure Potential is usually measured using the Pascal for Pressure. Note that the value of Pressure Potential is always positive.
Can the Pressure Potential be negative?
No, the Pressure Potential, measured in Pressure cannot be negative.
What unit is used to measure Pressure Potential?
Pressure Potential is usually measured using the Pascal[Pa] for Pressure. Kilopascal[Pa], Bar[Pa], Pound Per Square Inch[Pa] are the few other units in which Pressure Potential can be measured.
