The expansion of fertilizer manu- facture and use, the increase in fossil fuel combustion, the intensification of animal husbandry, and widespread cultivation of N2 fixing crops have all contributed to the dramatic increase in N inputs. The increase has been most rapid in Northern Hemisphere (NH) temperate ecosystems, but presently subtropical and tropical regions of Asia are also experiencing an explosive increase in N inputs to terrestrial ecosystems (W. Chameides, pers. comm.; Galloway et al. 1996). Projected increases in N deposition for these trop- ical and subtropical regions, with a high natural background of N inputs, exceed increases projected for temperate and arctic regions (Cleveland et al. submitted; Galloway et al. 1994; Holland \u0026amp; Lamarque 1997a). Compared to biological N fixation, N deposition is becoming a proportionately greater source of N to terrestrial and aquatic ecosystems worldwide (Vitousek et al. 1997). 6 The nitrogen contained in the atmosphere as N, 3. 9 * 10 Tg (Tg = 2 12 10 g), is the largest reservoir of N in the Earth system (Warneck 1988). However, this paper focuses on the nitrogen emissions and deposition that have been transformed from N2 into reactive forms that are biologically avail- able (e. g. Vitousek et al. 1997).\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Hardcover","offer_id":45283550101655,"sku":"9780792357049","price":7028.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9780792357049.webp?v=1769305291","url":"https:\/\/atlanticbooks.com\/products\/new-perspectives-on-nitrogen-cycling-in-the-temperate-and-tropical-americas-report-of-the-international-scope-nitrogen-project-9780792357049","provider":"Atlantic Books","version":"1.0","type":"link"}
