Brief NSRC research report. Growing scientific evidence suggests that various human activities may be responsible for depleting calcium from soils in the Northern Forest. Factors cited for calcium depletion include high acid additions to forest soils from acidic deposition, which both forces calcium to be washed out of the soil and frees up soil aluminum to inhibit uptake of calcium by plant roots. Because calcium is an essential plant nutrient, calcium deficiency could impair the long-term health and productivity of forests in the region.
