Abstract
Three methods to calculate the unsaturated conductivity of soil from its moisture characteristic were tested. Calculated values were compared with direct measurements of conductivity for both sorption and desorption for a sand. Also, comparisons were made for three soil materials. The method of calculation proposed by Millington and Quirk [1959], when matched at the saturated conductivity, gave good results.
