Item #d98jul81

"Boreal Forest Plants Take up Organic Nitrogen," T. Nasholm (Dept. Forest Genetics, Swed. Univ. Agric. Sci., S-901 83 Umeå, Sweden; e-mail: Torgny.Nasholm@genfys.slu.se), A. Ekblad et al.,Nature, 392(6679), 914-916, Apr. 30, 1998.

Plant growth in the boreal forest is generally limited by the availability of N, presumably because of the slow mineralization of soil organic N. This study of two tree species, a shrub, and a grass shows, however, that these plants bypass N mineralization. Results have major implications for our understanding of the effects of N deposition, global warming and intensified forestry.


Item #d98jul82

"Global Distribution of Nitrous Oxide Production and N Inputs in Freshwater and Coastal Marine Ecosystems," S.P. Seitzinger (Inst. Marine Sci., Rutgers Univ., New Brunswick NJ 08901; e-mail: sybil@imcs.rutgers.edu), C. Kroeze,Global Biogeochem. Cycles, 12(1), 93-113, Mar. 1998.

Globally, rivers and estuaries could account for about 20% of the current global anthropogenic N2O emissions. They are comparable to a number of previously identified sources, including direct emissions of N2O from soils induced by anthropogenic N inputs.


Item #d98jul83

"The Nitrogen Cost of Food Production: Norwegian Society," M. A. Bleken (Dept. Hort., POB 5022, N-1432 As, Norway; e-mail: marina.bleken@ipf.nlh.no), L.R. Bakken,Ambio, 26(3), 134-142, May 1997.

Uses Norway as an example to analyze the N flows within a society and the dissipation of N to the environment. Major reductions in the total consumption of N can be obtained by moderate changes toward a more vegetarian diet and better utilization of existing food. In contrast, recycling of waste at its lowest trophic level (compost) is very inefficient. A critical analysis of the human diet as well as the agricultural and food industries is necessary to reduce the human contribution to present and future N2O emissions.


Item #d98jul84

"Nitrous Oxide and Methane Fluxes from Perturbed and Unperturbed Boreal Forest Sites in Northern Ontario," C.L. Schiller (Dept. Chem., York Univ., North York ON M3J 1P3, Can.; e-mail: fs300367@sol.yorku.ca), D.R. Hastie,J. Geophys. Res., 101(D17), 22,767-22,774, Oct. 20, 1996.

Measurements in several settings showed N2O fluxes ranging from an uptake of 7.7 micrograms/m2/hr from a drainage ditch, to an emission of 3.1 micrograms/m2/hr from an unvegetated clear-cut. Methane fluxes ranged from an uptake of 23 micrograms/m2/hr from an upland forest, to an emission of 2900 micrograms/m2/hr from a drainage ditch.
