What are the different soil types?
1) “For soils, experience has shown that a natural system, i.e. grouping soils by their intrinsic property, behaviour, or genesis, results in classes that can be interpreted for many diverse uses. This is in contrast to a technical classification (such as the Fertility Capability Classification), where soils are grouped according to their fitness for a specific use. Natural systems are based strictly on presumed soil genesis, but modern hierarchical systems such as USDA soil taxonomy and the World Reference Base for Soil Resources use objective criteria (both field morphology and laboratory tests) as far as possible, to reduce disagreements among classifiers. Another approach is numerical classification, also called ordination, where soil individuals are grouped by multivariate statistical methods such as cluster analysis. This is supposed to create natural groupings without requiring any inference about soil genesis. In soil survey, as practiced in the United States, soil classificati
