Technology description
The process is representative for conventional agriculture. The technology is representative for faba beans growing in Norway. Due to lack of data, a simplified model for drying has been used. Also, fuel use has been estimated using a model (the DRIFT model) using field operations data (ploughing, harrowing, spraying, etc). Expert advice has been used to corroborate data from survey of farmers.
Quality level
Good
Location
Norway
Geographical representativeness
Data is representative for Norway since it’s based on a survey conducted in Norway and supported by expert advice from NLR and NIBIO. All regions were faba beans are grown in Norway are included.
Reference year
2017
Time representativeness
Farmers and experts are asked to give data on a representative year. They were asked to give the answers for 2017 if that was a representative year.
Other comments on methods approaches
Emissions of dinitrogen monoxide, ammonia, nitrogen dioxide and carbon dioxide are calculated based on the IPCC (2006). The emissions include direct and indirect emissions from application of mineral fertiliser, leaching and runoff and crop residues returned to soils and emissions from application of limestone. Changes in soil organic carbon (SOC) is modelled using the ICBM method.
Data treatment and extrapolations principles
Based on survey and expert advice.
