Previous experiments concerning the desorption of a horizontal column of uniform soil suggested that the moisture characteristic was not unique throughout the column. Further desorption experiments have been carried out on a vertical column. The results are consistent with those obtained previously, and give further information on the dual dependence of ψ on θ and on ∂ψ/∂ t .
