The discussion of the mutability of rocks and weathering processesleads to the understanding that these mineral substances are also perishable and serve, among other things, as starting material for soil formation.
The discussion of soils as the basis of agricultural production and as a protected asset covers a broad spectrum from physical soil properties (soil types, water, temperature and air balance) to chemical properties (pH value, sorption capacity, etc.) and to soil life (edaphon) and its functions.
Based on this, soil types be explained and understood, and soils can be assessed. In conjunction with climatic factors this results in soil assessment systemsthat are used, for example, in the creation of standard values.
