Comparison of nitrous oxide soil emissions measured on the two different demonstration sites

N₂O measured from soil

Values for GHG emissions in the two croppig systems are updated after the harvest of each crop, or at the end of the bare soil. Periods considered in the measurements are reported under the graphs.

Data are under validation, so the shown results aren’t definitive
