- Title
Soil Acidity and Manganese in Declining and Nondeclining Sugar Maple Stands in Pennsylvania.

- Abstract
The article discusses the soil acidity and Manganese in declining and nondeclining sugar maple stands in Pennsylvania. Accordingly, the hardwood forests of the state have been subjected to chronic atmospheric loading of acidifying agents, and high-elevation, unglaciated sites, sugar maples have experienced severe decline symptoms and mortality. The accelerated soil acidification, base cation leaching, and increased availability of toxic metals have been suggested as predisposing factors contributing to the declination. A manganese is an essential micronutrient which is also a phytotoxic metal that may be a factor associated with poor sugar maple health on soils vulnerable to acidification from anthropogenic sources.
