Grouping soils by their intrinsic property (soil morphology), behavior, or genesis, results in classes that can be interpreted for many diverse uses. Differing concepts of pathogenesis and differences in the significance of morphological features to various land uses can affect the classification approach. This is in contrast to a technical system approach to soil classification, where soils are grouped according to their fitness for a specific use and their edaphic characteristics. By using Fuzzy classification member function process can iterate the system accuracy.
