public class TextureClassesFunctions
extends Object
implements TextureClassPedoTransferFunction

Texture Class Functions are developed to determine soil hydraulic properties

... e.g. total porosity, residual water, field capacity, permanent wilting point, saturated hydraulic conductivity, ALPHA, and N for different soil texture classes based on USDA soil texture classification. The input data used for this estimation are the percentage of silt and clay, organic matter and bulk density.
