Soil has many functions in sustaining life. The prerequisite conditions for proper soil functioning may be expessed in terms of quality. Chemical quality of soil is predominantly determined by behaviour of compounds in soil. Compound behaviour is the result of the interactions of properties of the compounds and of the soil system under consideration. These can satisfactorily be described by applying methodical rules as derived in soil chemistry and soil physics. This is elaborated with examples referring to the static situation prevailing at adsorptive equilibrium, and to the dynamic situation of compound displacement in soil. The variability of soil properties appears to be of major concern. In these examples, attention is limited to the behaviour of cadmium in soil.
