Acid rain and forest productivity
Conference
·
OSTI ID:6076399
Acid rain can cause increases or decreases in forest productivity depending on site nutrient status and the duration and rate of inputs. Some acid irrigation studies have shown short-term growth increases due to increased N availability, yet long-term growth reductions remain theoretically possible because of cation depletion and toxic aluminum accumulations in soils. It cannot be overemphasized that the problem of assessing acid rain effects on forest productivity is one of quantification. Generalization about acid rain effects without reference to the amount of acidic input and site nutrient conditions are hazardous.
