Title: Data transformations between soil texture schemes
Abstract: Summary Various soil texture schemes are in current use. These differ in the size ranges of their particle fractions. There is a need to establish simple methods to correlate these conventional schemes. Therefore I have defined closed‐form exponential and power law functions to fit models to cumulative particle‐size distribution data. I have tested the functions for their suitability (i) to represent cumulative particle‐size distribution curves and (ii) to transfer data between distributions that differ in the size ranges of the particle fractions. I found that closed‐form exponential functions adequately represent the cumulative particle‐size distributions of fine‐textured soils (clay, silty clay, silty clay loam, clay loam, silt loam and loam texture), whilst closed‐form power functions better describe the cumulative particle‐size distributions of coarse‐textured soils (sand, loamy sand, sandy loam, sandy clay and sandy clay loam texture). The functions defined are found to be suitable to transfer data between different texture schemes. The use of this approach is illustrated by examples of data transformations between three widely used soil texture schemes: ISSS, Katschinski's and USDA.
