BIOGEOCHEMICAL CYCLES: NITROUS OXIDE
"Uncertainties in the Global Source Distribution of Nitrous
Oxide," A.F. Bouwman (Natl. Inst. Public Health &
Environ. Protect.-RIVM, POB 1, 3720 BA Bilthoven, Neth.), K.W.
Van der Hoek, J.G.J. Olivier, J. Geophys. Res., 100(D2),
2785-2800, Feb. 20, 1995.
Compiled emission inventories with 1· x 1· resolution from
fertilized arable land, animal excreta, soils after clearing,
fossil fuel and fuelwood combustion, and industrial N2O
sources. Oceanic N2O emissions may be more important
than assumed in recent global N2O budgets, with a
major portion stemming from the 30·-90·S zone. N2O
emission from animal excreta is a significant global source.
There are major uncertainties about emissions in the tropics.
"Nitrogenous Fertilizers: Global Distribution of Consumption
and Associated Emissions of Nitrous Oxide and Ammonia," E.
Matthews (Inst. Space Stud., NASA-Goddard, New York NY 10025), Global
Biogeochem. Cycles, 8(4), 411-439, Dec. 1994.
In the mid-1980s, contributions to global N fertilizer use
were 37% in East Asia, 17% in North America, 14% in western
Europe, and 40% in the tropics and subtropics. No measurements of
fertilizer-derived N2O emissions are available for
agriculture in the tropics and subtropics, where use is
increasing rapidly, so relative contributions of climatic regions
to current and future emissions are uncertain. Estimates yearly
increases in N2O emissions from fertilizer use to be
<1% to 3% of the current growth of atmospheric N2O.
