Nitrogen saturation in a high elevation New England spruce-fir stand☆
TLDR
In this article, high rates of nitrogen (N) deposition were first postulated as a cause of N saturation (i.e., the availability of NH4-N and NO3-N in excess of total combined plant and microbial nutritional demand) and spruce mortality during the 1980s.About:

TL;DR: In the US, nitrogen deposition remains relatively constant in the northeastern United States and is increasing in the Southeast and the West (Fenn et al. as mentioned in this paper, 2003), while acid acid deposition is increasing.

TL;DR: In this article, the authors identified forested areas that exhibit symptoms of N excess, analogous to overfertilization of arable land, and showed that some forests receiving chronic N inputs may decline in productivity and experience greate...
Is Nitrogen Deposition Altering the Nitrogen Status of Northeastern Forests
John D. Aber,Christine L. Goodale,Scott V. Ollinger,Melinda D. Smith,A. Magill,Mary E. Martin,Richard A. Hallett,John L. Stoddard,N. Participants +8 more
TL;DR: In this article, the authors present a new synthesis of existing data sets for the northeastern United States, intended to answer a single question: Is N deposition altering the N status of forest ecosystems in this region?

The globalization of nitrogen deposition: consequences for terrestrial ecosystems.
TL;DR: Some of the conditions under which anthropogenic impacts can be significant, some of the factors that control variations in response, and some areas where uncertainty is large due to limited information are pointed to.

Journal ArticleDOI
Nitrogen saturation in northern forest ecosystems
TL;DR: In this article, the authors describe ways in which excess nitrogen from fossil fuel combustion may stress the biosphere, and the complexity of these effects on water quality and on forest nutrition is discussed.

Effects of Forest Cutting and Herbicide Treatment on Nutrient Budgets in the Hubbard Brook Watershed-Ecosystem
TL;DR: Large increases in streamwater concentration were observed for all major ions, except NH4+, SO4 = and HCO3—, approximately five months after the deforestation, and an inverse relationship between sulfate and nitrate concentrations in stream water was observed in both undisturbed and deforested situations.

Use of Calcium/Aluminum Ratios as Indicators of Stress in Forest Ecosystems
TL;DR: In this paper, the Ca/Al molar ratio of the soil solution provided a valuable measurement endpoint or ecological indicator for identification of approximate thresholds beyond which the risk of forest damage from Al stress and nutrient imbalances increases.

Aboveground Production and N and P Cycling Along a Nitrogen Mineralization Gradient on Blackhawk Island, Wisconsin
TL;DR: In this article, a series of edaphic climax forests was highly correlated with field measurements of soil N mineralization (26-84 kg ha-- yr-'; r2 = 0.902, P <.001) and with soil silt + clay content.
