As elevated nitrogen deposition increases soil nitrogen available to plants, phosphorus may become less available in forested ecosystems. Research at the Bear Brook Watershed in Maine has suggested that experimental inputs of nitrogen have increased nitrogen availability, decreased fine root biomass, depleted soil base cations such as calcium and magnesium, and increased mobility of certain forms of soil aluminum with which phosphorus is often associated, potentially mobilizing phosphorus at the same time.
