Chemical Properties and Processes,re the storage and supply of nutrients, the sorption and degradation of contaminants, as well as the buffering of acid deposition. The chemical processes taking place at biogeochemical interfaces are of outstanding importance. About 40–60 % of the soil volume consists of pores, which can be filled w
