dc.description.abstractNitrogen fertilization of agricultural crops increases nitrous oxide (N2O) emissions from soils. The data used in this study were obtained from a long-term field experiment for corn, winter wheat and rapeseed cultivated on loam and sandy loam soils, and fertilized with the recommended nitrogen doses (kg N ha1) of 150, 120 and 150, respectively. The purpose of the study was to determine the relationship between yield-scaled N2O emissions (Eys) and nitrogen yield (Yn), as well as nitrogen use efficiency (NUE) and nitrogen surplus (Ns). It was found that the provisionally determined desired yield values (Yn>80 kg N ha-1), NUE (50-90%) and N surplus (Ns<80 kg N ha-1) can be considered as nitrogen utilization efficiency characteristics, reducing yield-scaled N2O emissions. Our study showed that these emissions for desired parameters Yn, NUE and Ns were ≤25.6, 28.3-18.6 and ≤30.9 g N2O_N kg Yn-1, respectively. Estimated Eys were 1.5-2.6 time higher than the minimum emission and 2.2-3.6 times lower than the maximum emission recorded in the analyzed data series. In conclusion, the reduction of nitrogen surplus in our field experiment, significant for environmental protection, did not result in loss of crop yields; on the contrary, it led to their growth.
