Comparison of Soil Freezing Curve and Soil Water Curve Data for Windsor Sandy Loam

reportActive / Technical Report | Accession Number: ADA202365 | Open PDF

Abstract:

Unfrozen water content as a function of temperature was measured in the laboratory using nuclear magnetic resonance NMR for a Windsor sandy loam soil. The data were related to previously measured soil moisture retention data through the modified Clapeyron equation with suitable adjustment for surface tension. The results show the usefulness of extending the soil freezing curve to temperatures only slightly below freezing and the soil water curve to very great suction.
