Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]
In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...
