Abstract
Models of nutrient uptake by tree roots and subsequent release on litter decomposition show that, where ammonium is the dominant nitrogen source, acidity as a result of excess cation uptake is equivalent to that introduced in acid rain, but because that in acid rain is introduced together with mobile anions this is the more likely to reach streams, provided that drainage over or through the soil is so rapid that neutralization reactions are not completed. In polluted regions the neutralization process within a forest canopy appears to fail in late winter, thus accentuating the episodicity of hydrogen ion input to the soil.
