Download N2O emission factors EF1 for fertilisers

This study was conducted to determine EF1 values for ammonium sulphate (AS) and diammonium phosphate (DAP) and compare them with the value for urea under the same field conditions, with the aim of providing evidence to assess whether it is feasible to apply the same country-specific EF1 value used for urea when determining the emissions from the NH4+-based N fertilisers in the New Zealand inventory calculations.
