Perry, Charles H.; Amacher, Michael C. 2012. Patterns of soil calcium and aluminum across the conterminous United States (Chapter 9). In: Potter, K. M.; Conkling, B. L., eds. Forest Health Monitoring: 2008 National Technical Report. GTR-SRS-158. Asheville, NC: U.S. Department of Agriculture, Forest Service, Southern Research Station. p. 119-130.

The health and growth of forests depends upon soil nutrients. Calcium (Ca) is a cation - positive ion - used by plants to build cell walls (Marschner 1986). It is also involved in root and leaf development and the activation of plant enzymes (Potash and Phosphate Institute 1995). Soils that develop in areas with low rainfall tend to have greater Ca supplies than soils that form in humid regions of the country, and within any one soil profile, more Ca typically is found in lower parts of the soil profile than at the surface (Pritchett and Fisher 1987). Acidic deposition leads to soil Ca depletion (Lawrence and others 1999). Soil Ca depletion is the most important means by which acid deposition affects forest health (Fenn and others 2006).
