Abstract:

A method for tensiometer measurements of soil moisture tension at air temperatures below 0C is described. A column of decahydronaphthalin decalin, density 0.89 forms the hydraulic connection between the water in the tensiometer ceramic cell and the Hg-manometer. Experimental results and some restrictions of the method especially the necessary solar radiation protection are discussed.
