摘要：

An improved technique for measuring soil-water desorption curves of a large number of soil cores was tested. A tensiometer-pressure transducer combination for establishing equilibration time proved more reliable than the traditional weight-loss criterion. The consistency and reproducibility of desorption curves was demonstrated using data for hysteretic loops as well as standard deviations of water contents at each pressure head on similar soils. - from Authors
