Estimation of N2O emission factors for soils depending on environmental conditions and crop management [PDF]

, 2009
Nitrous oxide (N2O) contributes 8% to anthropogenic global warming, of which about one third are direct emissions of agricultural soils. These N2O emissions are often estimated using the default IPCC 2006 emission factor of 1% of the amount of N applied ...
