Henderson, G. S.; Swank, W. T.; Waide, J. B.; Grier, C. C. 1978. Nutrient budgets of Appalachian and Cascade region watersheds: a comparison. Forest Science. 24(3): 385-397.
Precipitation inputs and streaniflow outputs of nitrogen, calcium, potassium,magnesium, and sodium were compared for two deciduous forest watersheds and a conif-erous forest watershed. While nitrogen inputs varied by nearly tenfold among the water-sheds, ammonium and nitrate discharge in strea.mflow was uniformly small resulting in netaccumulation within all three ecosystems. In contrast, cation discharge -was more variableamong the watersheds than cation input and was strongly related to the bedrock of eachwatershed. The internal distribution and cycling of nitrogen, potassium, and calciumwithin each of the three watershed ecosystems were also compared. There were inter-pretable differences between nutrient cycling patterns in the coniferous and deciduous for-ests. Overall, however, all three ecosystems were effectively retaining and recycling thesenutrients. FOREST SCI, 24:385-397,
