68  Project emissions—synthetic fertiliser
 (1) The nitrous oxide emissions from synthetic fertiliser applied to a carbon estimation area during the reporting period must be calculated using the following formula, where the sum is over all synthetic fertiliser groups fij that have been defined in accordance with subsection 51(2):
  Equation SF4

      Where:

 =  total nitrous oxide emissions from synthetic fertiliser applied to carbon estimation area A during the reporting period; t CO2-e.
  =  quantity of synthetic fertiliser group fij applied to carbon estimation area A during the sequestration period of the reporting period; t fertiliser.
 =  percentage nitrogen content of fertiliser (f) in synthetic fertiliser group fij, as provided by the manufacturer; t N / t fertiliser.
  =  default emission factor for synthetic fertiliser group fij, as set out in Tables 5 and 6 of the Standard Parameters and Emissions Factors; t CO2-e / t N.
 (2) The total emissions from synthetic fertiliser applied to each relevant carbon estimation area during the reporting period must be calculated using the following formula:
  Equation SF5

      Where:

 =  total emissions from synthetic fertiliser applied to carbon estimation area A during the reporting period; t CO2-e.
 =  total nitrous oxide emissions from synthetic fertiliser applied to carbon estimation area A during the reporting period; t CO2-e.
  =  quantity of urea applied to carbon estimation area A during the sequestration period of the reporting period; t urea.
  =  National Inventory Report emission factor for carbon dioxide emissions from urea; t CO2-e / t urea.
 (3) The mean annual emissions from synthetic fertiliser applied to each relevant carbon estimation area during the reporting period must be calculated using the following formula:
  Equation SF7

      Where:

  =  mean annual emissions from synthetic fertiliser applied to carbon estimation area A during the reporting period; t CO2‑e / y.
  =  total emissions from synthetic fertiliser applied to carbon estimation area A during the reporting period; t CO2‑e.
 =  length of the sequestration period of the reporting period for carbon estimation area A; y.
