The discussion of the convertibility of rocks and weathering processes leads 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 a basis for agricultural production and as a protected asset spans a wide range from physical soil properties (soil types, water, temperature and air balance) to chemical ones (ph value, sorption capacity, etc.) and all the way to soil life (edaphon) and its properties Features.
On this basis, soil types explained and understood and soils can be evaluated. In connection with climatic factors , soil assessment systems arise that are used, for example, in the creation of standard values.
