Abstract: The measured data of N2O emissions from conventional tillage (CT) and reduced tillage (RT) combined with unamended control (N0) and addition of nitrogen fertilizers (N1) were used to verify the DNDC model from cropland during February – November in 2013 in Slovakia (covering also the growing season of red clover). Generally, the DNDC model underestimated the total N2O emissions with relative deviation between observed and simulated total seasonal N2O emissions (kg N2O-N ha-1) ranging from 83-98 % for all treatments (CTN0, CTN1, RTN0 and RTN1) as compared to measured data.
