Soil Water Thermodynamic to Unify Water Retention Curve by Pressure Plates and Tensiometer
Frontiers in Earth Science, 2014 The pressure plate method is a standard method for measuring the pF curves, also called soil water retention curves, in a large soil moisture range from saturation to a dry state corresponding to a tension pressure of near 1500 kPa. However, the pressure
