Soil water potential is measured either by measuring some property of the soil which changes with the water potential, or by equilibrating the liquid or gas phase of the water in some reference medium with the liquid phase of the soil and measuring some property of the water in the reference medium. Devices commonly used to measure soil water potential are tensiometers, thermocouple psychrometers, electrical resistance sensors, thermal conductivity sensors, and correlations with water contents… CONTINUE READING
