Abstract

The relationships between the soil water repellency and soil moisture were studied by measuring WDPT using 10 different water repellent soils collected from Israel. A single peak curve correlation of the relationships between the WDPT and soil moisture was obtained after analysis. Three mathematic models, namely Gaussian, Lorentzian and Lognormal distributions were used for fitting the models by regression analysis, and the Lorentzian distribution was found to be the best model for the practical use. The peak soil moisture, the peak WDPT and the critical soil moisture can be computed by the model of part measured WDPT and soil moisture. It can provide the theory for amelioration of soil and compare of the different repellent soils.
