AB  - Pulse diffusive nitrous oxide (N(2)O) emission following water application is 
      well documented, whereas N(2)O emission caused by soil water-air displacement 
      during the watering process (termed as soil degassing) has been largely 
      overlooked. Watering-induced N(2)O emissions from ten different soils in China 
      were quantified, and found to range from 74.4 +/- 6.7 to 678.1 +/- 36.6 mug N(2)O 
      m(-2) h(-1) in surface watered (SW) soils, and from 45.6 +/- 4.4 to 358.1 +/- 23.6 mug 
      N(2)O m(-2) h(-1) in subsurface watered (SUW) soils. These N(2)O fluxes were much 
      larger than the diffusive N(2)O flux from the same soil either under dry 
      (7.9%-9.6% water filled pore space, WFPS) or wet (85.1%-93.6% WFPS) conditions. 
      The watering process (the water infiltration process upon irrigation/rainfall or 
      the process of shallow groundwater uplifting) resulted in massive N(2)O 
      emissions.
