At the end of the equilibrium at 300 kPa, soil cores were
sampled to determine soil water content by oven drying at 105 C
for 24 h. The water retention curve was simulated with van
Genuchten function (van Genuchten, 1980). The pore size
distribution was calculated from the soil water retention curve
following the capillary rise function (Kutílek and Nielsen, 1994):
D ¼ 300=H (4)
where, the equivalent cylindrical diameter of pores, D(mm) was
given by the change of pore cylinders dewatered at the water
potential, H(kPa). The pore size was classed into >30, 30–1 and
