Short summary
We continuously measured CH4 and N2O fluxes on two pastures that differed with respect to management. Two micrometeorological ratio methods were used; one was more suitable for daytime and the other for night-time. Over a year, both methods indicated both sites as net sources of CH4 and N2O, similar to other managed grasslands. At the irrigated, fertilised and rotationally grazed site, the N2O emissions were 1.21 (±0.15) % of the nitrogen inputs from animal excreta and fertiliser application.
