- •
Calculation of CO2eq emissions in sugar beet cultivation using the tool Biograce.
- •
Practice data from 1181 farms were used.
- •
N fertilization is the main source of CO2eq emissions in sugar beet cultivation.
- •
On average, less N2O emissions were produced by using organic fertilizers only.
- •
Sugar yield is independent of the intensity of N fertilization.
- •
CO2eq emissions per t sugar yield between the years were mainly based on differences in yield and not on differences in management.
