چکیده
The manuscript “Uncertainties in model predictions of nitrogen fluxes from agroecosystems in Europe” describes a study in which the propagation of uncertainty in input parameters and coefficients used in the model INTEGRATOR to estimates of fluxes of reactive nitrogen (N2O, NOx, NH3, leaching and runoff of N) is assessed. The authors study both the quantitative overall uncertainty of these Nr fluxes at three different resolutions – the spatial calculation units used, country-level, and EU27 wide – and the contribution of the grouped uncertain parameters to the final uncertainty estimates. A robustness test is included as well. Particular attention has been paid to the spatial correlation of the data, which is a major determinant of the results of the study.

We thank the reviewer for the appraisal and suggestions, which have helped us to improve the manuscript. We have carefully tried to address the issues raised and to revise the paper accordingly. In the revision we have been able to incorporate nearly all the suggestions of the referees as explained in our responses to each reviewer. Below the essence of the questions and suggestions of the revi...

-Page 6054: The example of de Vries et al. (2003) is given, stating that this study did not cover the uncertainty due to spatial model inputs. Readers would expect then that in this paper the uncertainty in spatially explicit data is analyzed. If this is so important, why not include this aspect. Why is it beyong the scope of this work (page 6059)? Computing time can not be an argument any longer.
متن کاملRelation between nitrogen nutrition index and production of spring malting barley
Although the nitrogen nutrition index (NNI) is a widely used indicator of plant nitrogenstatus, no model of NNI calculation for spring barley (Hordeum vulgare) reflecting also specificmalting requirements on grain has been published. The aim of this study was to determinean optimal range of the nitrogen nutrition index (ratio of nitrogen concentration in shootbiomass to critical nitrogen concen...
