Soils modify the composition of incoming precipitation passing through them to streams or lakes by interaction between the dissolved constituents and ions adsorbed on the clays and organic matter that make up the soil exchange complex. Hydrogen and aluminium are released when those ions adsorbed on the exchange complex greatly exceed adsorbed nutrient bases. Conversely, high levels of adsorbed bases buffer the soil against acidity in incoming precipitation. Basic ions on the exchange complex can be replenished from easily weatherable soil minerals and afford long-term buffering against acidification.
