LCI Method PrincipleAttributional
LCI Principles DeviationsAttributional LCI methods were used.
LCI Method ApproachesAllocation - mass
LCI Method DeviationsMass allocation was the main allocation approach for field inputs and emissions. Hay for seeds was subtracted from yield.
Modelling ConstantsSummary of synthetic fertilization per tonne of hay: 5.0 kg N, 3.2 kg P, 1.7 kg S
Modelling Constant DeviationsNA
Data Cutoff/Completeness PrinciplesHay left in the fields was out of scope. CO2 removal from soil due to historical increased use of perennial crops (such as hay) in Canada was included (see the Canadian GHG inventory part 2 for more information).
Deviations from Cutoff/Completeness PrinciplesNA
Data Selection/Combination PrinciplesWhere provincial data was unavailable, data from another region (another province or Canada) or for field crops in general was used. Where data was not available over 10 years, data from a shorter period was used.
Deviations from Selection/Combination PrinciplesNA
Data Treatment and Extrapolation PrinciplesExported hay was assumed to be irrigated and corresponding irrigation water was excluded from the LCI.
Deviations from Treatment and Extrapolation PrinciplesNA
Supply Coverage100
