In this study we investigated the effect of mouldboard ploughing (MP), shallow cultivation (SC) and no-tillage (NT) methods on N2O emission of a Central European long-term field experiment. We measured N2O fluxes and environmental parameters (soil moisture and temperature) in three replicates per treatment on a biweekly to mounthly basis during two and a half year period. Besides regular measurements we carried out additional occasions timed to heavy rainfalls. N2O fluxes occured after fertilization and on soils under high soil moisture conditions only, during spring and autumn. The average N2O emission for the whole experimental period was the highest in NT (0.025±0.045 µg N2O m-2 s-1), which was significantly higher (p<0.005) than in MP (0.004±0.003 µg N2O m-2 s-1) or SC (0.003±0.003 µg N2O m-2 s-1). Soil mositure was a significant (p<0.005) environmental driver of N2O emissions in NT treatment.
