Soil water retention curve of agrogray soils: Influence of anisotropy and the scaling factor [PDF]
Eurasian Soil Science, 2014 The soil water characteristic or soil water retention curve (WRC) of medium-loamy gray forest soil horizons was studied in cylinder-shaped samples of disturbed and undisturbed structure. The sample height varied within 2-4 cm and the diameter within 4.5-10 cm.

Adjusting the water retention curve for retractable soils
DYNA, 2021 The soil water retention curve (SWRC) relates moisture to soil water retention energy (matrix potential). The calculation of the volumetrichumidity considers the sample volume. In retractable soils, this volume varies according to the drying or wetting of the soil, which can result in errors in the calculated moisture. The objective of this study is to
