Soil acidification caused by acid rain and other human-caused factors can induce soil calcium depletion and increased bio-availability of aluminum. Tree declines associated with calcium depletion and increased aluminum toxicity in forest soils occur throughout the world including the Northern Forest region. Changes in soil calcium and aluminum availability may trigger stress and disruptions in carbohydrate relationships in forest trees.
