Abstract

Two soil chronosequences of mountainous ecosystems in Switzerland served as the basis to calculate the accumulation of soil organic matter, transformation of pedogenic Fe and Al and net losses of the main elements (Ca, Mg, K, Fe, Al, Mn and Si) by means of mass-balance calculations. Elemental losses due to deglaciation and exposure to the weathering environment were calculated. The greatest changes in the soil chemistry of these alpine soils on granitic host material occurred within the first 3000-4000 years of soil development. Later, the weathering rates decreased rapidly
