Abstract:Soil hydraulic properties can be estimated from soil basic properties such as soil texture,bulk density and soil organic matter,which can be obtained easily.These estimating functions are called as Pedo-Transfer Functions(PTFs).Based on the summary of relevant study on PTFs,data collected from Huabei Region was analyzed in this paper.Some PTFs have been established and verified.It was found that the PTFs were useful in the estimation of soil hydraulic parameters in a regional scale.
