N2O Emissions from Rainfed Sugarcane Plantation

The effects of nitrogen fertilization on N2O emissions from a rubber plantation

To gain the effects of N fertilizer applications on N2O emissions and local climate change in fertilized rubber (Hevea brasiliensis) plantations in the tropics, we measured N2O fluxes from fertilized (75 kg N ha(-1) yr(-1)) and unfertilized rubber plantations at Xishuangbanna in southwest China over a 2-year period. The N2O emissions from the fertilized and unfertilized plots were 4.0 and 2.5 k...

New estimates of direct N2O emissions from Chinese croplands

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Nitrous oxide (N 2 O) is a long-lived greenhouse gas with a large radiation intensity and it is emitted mainly from agricultural land. Accurate estimates of total direct N 2 O emissions from croplands on a count...

Soil N2O and NO emissions from an arid, urban ecosystem

[1] We measured soil nitrogen (N) cycling and fluxes of N2O and NO in three land-use types across the metropolitan area of Phoenix, Arizona. Urbanization increased N2O emissions compared to native landscapes, primarily due to the expansion of fertilized and irrigated lawns. Fluxes of N2O from lawns ranged from 18 to 80 mg N m!2 h!1 and were significantly larger than managed xeric landscapes (2....
