Measurement of stony soil water retention curve using HYPROP

We used the HYPROP (HYdraulic PROPerty analyzer, Decagon Devices Inc) device for the simplified evaporation method (SEM), which measures the WRC with simultaneous measurements of matric potential using two miniature tensiometers and sample average water content using mass balance to measure the stony soil water retention function. Mixtures of Millville silt loam with coarse sandstone and fine sandstone and mixtures of Wedron sand with pumice were evaluated considering six different volumetric stone contents (v =0, 0.05, 0.1, 0.2, 0.3, 0.4 ).
