WitrynaSoil classification is a means of organizing knowledge about soils. It is common to use hierarchical schemes because there are many soils and they have numerous physical, chemical, and biological properties. Protocols for designing such systems have been widely used and are summarized in eight principles. Witrynacertain soil processes in different ways, as described in the section on functional classification in Chapter 2. Soil macrofauna play a particularly important role in soil aggregation and porosity as a consequence of their burrowing and mixing activities. This in turn affects the environment (aeration, soil moisture, etc.) for other soil organisms.
