“…Because the Andisols in these study sites are typically high in N, even without elevated N deposition, no clear patterns of increased net N mineralization, nitrifi cation, soil N or foliar N were observed (Fenn et al 2002b). Nitrogen fertilization sometimes results in little plant growth response (Fenn et al 2002b(Fenn et al , 2006; preliminary evidence suggests a depressive growth eff ect from added N in the Mexico City air basin in some cases, possibly because added N induces greater phosphorus (P) defi ciency (Fenn et al 2006(Fenn et al , 2002b. Widespread P defi ciency, presumably because of the high P-fi xation capacity of these Andisols (Shoji et al 1993), and the high inherent N fertility in these study sites, may enhance the tendency of these catchments to leach NO 3 -with increasing atmospheric N deposition.…”

Human activity in the last century has led to a substantial increase in nitrogen (N) emissions and deposition. This N deposition has reached a level that has caused or is likely to cause alterations to the structure and function of many ecosystems across the United States. One approach for quantifying the level of pollution that would be harmful to ecosystems is the critical loads approach. The critical load is defi ned as the level of a pollutant below which no detrimental ecological effect occurs over the long term according to present knowledge.The objective of this project was to synthesize current research relating atmospheric N deposition to effects on terrestrial and aquatic ecosystems in the United States and to identify empirical critical loads for atmospheric N deposition. The receptors that we evaluated included freshwater diatoms, mycorrhizal fungi and other soil microbes, lichens, herbaceous plants, shrubs, and trees. The main responses reported fell into two categories: (1) biogeochemical, and (2) individual species, population, and community responses.The range of critical loads for nutrient N reported for U.S. ecoregions, inland surface waters, and freshwater wetlands is 1 to 39 kg N ha -1 y -1. This broad range spans the range of N deposition observed over most of the country. The empirical critical loads for N tend to increase in the following sequence for different life forms: diatoms, lichens and bryophytes, mycorrhizal fungi, herbaceous plants and shrubs, trees.The critical loads approach is an ecosystem assessment tool with great potential to simplify complex scientifi c information and effectively communicate with the policy community and the public. This synthesis represents the fi rst comprehensive assessment of empirical critical loads of N for ecoregions across the United States.

“…The effects of fertilisation with these nutrients on both plant growth and chemical contents of leaves have been extensively studied in Eucalyptus forests (HUNTER, 2000;GRACIANO et al, 2005;FENN et al, 2006).

-Forestry plantations should be regarded as an alternative sustainable land-use system in degraded savannah areas. They contribute to the maintenance of productive processes in degraded soils that are of economic importance for local inhabitants; in addition, in the ecological sense, timber and non-timber products from planted forests reduce the exploitation pressure on native forests. Eucalyptus plantations on degraded savannahs in the northern Brazilian Amazon may help to reduce exploitation pressure on native forests. However, there is no information regarding the nutrients rates that would allow faster eucalyptus growth in that region. A trial was installed in an Yellow Latosol (Oxisol) soil type adopting a one-half-type fractional factorial design with four rates of N, P, and K. Functions were adjusted for the dependent variables height, diameter at breast height (DBH), leaf tissue nutrient content, and soil-chemical attributes. Interaction N versus K was observed on tree height with a maximum of 7.8 m recorded at 200 kg ha -1 of N and 50 kg ha -1 of K. Phosphorus fertilization promoted greater DBH growth with maximum value at 120 kg ha -1 of P; however, the highest gain was obtained at 30 kg ha -1 of P. The NPK rates that maximized Eucalyptus camaldulensis growth were 200, 30, and 50 kg ha -1 , respectively.

Isotopic and nutritional evidence for species‐ and site‐specific responses to N deposition and elevated CO₂ in temperate forests

In this study we show that the effect of rising atmospheric CO 2 levels on forest productivity is influenced by changes in nutrient availability caused by nitrogen (N) deposition. We used a dual-isotope approach (δ 15 N and δ 13 C), combined with dendrochronological and nutritional analyses, to evaluate the response of two dominant tree species in natural forest ecosystems near Mexico City (Pinus hartwegii-pine; Abies religiosa-fir). Our analysis focuses on changes that occurred over the past 50 years at two sites, one under high and one under low N deposition rates. Analyses of carbon isotope composition indicate increasing water-use efficiency in response to rising CO 2 levels for both species and sites but this effect did not lead to improved tree growth. The magnitude and direction of shifts in 13 C discrimination indicate a process of acclimation that varied with the rate of N deposition and species traits. Since the 1960s, strong negative responses to N deposition have been observed in fir trees, which showed altered foliar nutrition and growth decline, while the negative impacts of N deposition on pine trees remained undetectable until the 1990s. In recent years, both species have shown significant growth decline under high N deposition despite increasing atmospheric CO 2 . Multivariate analysis of leaf nutrients indicates that growth decline was prompted by depleted soil macronutrient (P, K, and Ca) and micronutrient (Cu, Fe, Zn, and Mn) availability. At both sites, fir trees were a better indicator of N deposition due to differences in canopy rainfall interception.
