Conclusions
• (+) Experiment design and data structure to develop improvements
in GHG inventories

Conclusions
• (+) Experiment design and data structure to develop improvements
in GHG inventories
• (-) To obtain N2O EF for Argentina will be difficult

Conclusions
• (+) Experiment design and data structure to develop improvements
in GHG inventories
• (-) To obtain N2O EF for Argentina will be difficult
• (+) The possibility of measuring during less than 12 months is
promising
