Effect of Zero Growth of Fertilizer Action on Ecological Efficiency of Grain Production in China under the Background of Carbon Emission Reduction
Round 1
Reviewer 1 Report
The topic selection is meaningful. However, some content of this paper need to be further optimized. And I have some considerable concerns that would be worth addressing. I would like to give some suggestions as below first and if possible, give detailed suggestions for the revised paper in future.
Several problems need to be considered:
1. The paper is not traditional writing framework and lack of discussion part.
2. The comparison with related studies is not sufficient.
3. Please discuss the limitations and future directions of the paper appropriately. For instance, what factors might influence existing conclusions?
4. It would be interesting to discuss recommendations for grain production management in the context of carbon neutrality, since carbon emissions are directly related to grain production and fertilizer use;
5. The current conclusions are all conceivable and lack of innovative perspective. The paper doesn't seem to bring enough new knowledge.

Reviewer 3 Report
The article entitled Study on the effect of zero growth of fertilizer action on ecological efficiency of grain production in China is approaching an interesting topical theme. The paper qualifies by the applied methodology and validation of results to be published in Sustainability journal.
As minor changes to be clarified by authors before publication I recommend:
- To better underline in the first part the advantages represented by the application of a SBM model for their analysis
- Are there any limits imposed by the model in the analysis ? This should be explained in the limits and possible further continuation of the study
- What is the purpose of the regional analysis and what the eastern, central and western region represents in geographical terms ?
