Reviewer 1 Report

Comments and Suggestions for Authors

1.       In the abstract section the U:Mt:PPP ratios measurement units should be clearly mentioned (mass ratios, molar ratios, etc.)

2.       Abbreviations should be explained prior to their use (see page 2, line 49, NUE).

3.       Typos mistakes: page 2, line 47 “kang and Wang”; line 54 “above literatures”; page 2, line 73 “In order to synthesis a novel”; page 4, line 153 ”XRD Low Angel analysis”. Please check the manuscript and correct it.

4.       Double references are introduced in some phrases (see page 2, lines 59-60).

5.       The last paragraph of Introduction section seems to be mostly a literature review than a paragraph emphasizing the novelty of this study. Please rephrase this section.

6.       No references for the chemical composition of the Mt is provided.

7.       Page 3, line 104:  it is not clear what “humidity 8 %” is meaning. Please be more specific.

8.       Page 3, line 107: the measurements units in “1.4-2 T/24 hs” are not clear.

9.       Details about the instruments used and most important data should be provided, without emphasizing step by step the procedures (see page 3, lines 118 – 122).

10.   Reference [28] is wrongly written (page 4, line 141)

11.   The SRU abbreviation is probably used in some statement to indicate the fertilizers (page 4, line 176), as it means something else.

12.   Are the XRD patterns in Figure 2 normalized. If so, how? Same question for the FTIR spectra in Figure 3.

13.   The N-H name in Figure 3 appears several times. If this belongs to different types of bonds, please indicate them differently.

14.   The authors are mentioning that “Release pattern data were shown as means ± standard deviation. Each treatment had 3 replicates. Statistical data analyses were performed using the student t-test.” but no numerical values and student t-test results are given in the manuscript.

Regarding your comment, the following corrections have been made: page 2, line 47; line 54; page 2, line 73; and page 4, line 153.

  1. Double references are introduced in some phrases (see page 2, lines 59-60).

Regarding your comment, the double references introduced on page 2, lines 59-60, have been fully corrected.

  1. The last paragraph of Introduction section seems to be mostly a literature review than a paragraph emphasizing the novelty of this study. Please rephrase this section.

Regarding your valuable comment, the last paragraph of the introduction section now presents an innovative aspect of this research.

  1. No references for the chemical composition of the Mt is provided.

Regarding your comment, a reference has been provided for the chemical composition of the Mt.

  1. Page 3, line 104: it is not clear what “humidity 8 %” is meaning. Please be more specific.

Regarding your comment, 8% humidity (page 3, line 104) refers to adding 8 ml of water to the material, which is equivalent to 8% of the total sample weight. This has been fully corrected in the article.

  1. Page 3, line 107: the measurements units in “1.4-2 T/24 hs” are not clear.

Regarding your comment, the units of measurement (page 3, line 107) refer to the machine's production capacity of 2 tons per 24 hours. This has been fully corrected in the text.

  1. Details about the instruments used and most important data should be provided, without emphasizing step by step the procedures (see page 3, lines 118 – 122).

Regarding your comment, the reference (page 4, line 141) was a typo and has been corrected.

  1. The SRU abbreviation is probably used in some statement to indicate the fertilizers (page 4, line 176), as it means something else.

Regarding your comment, the abbreviation SRU (page 4, line 176) stands for slow-release urea fertilizer. This has been corrected in the article.

  1. Are the XRD patterns in Figure 2 normalized. If so, how? Same question for the FTIR spectra in Figure 3.

Regarding your valuable comment, XRD normal means the angle range in which the XRD analysis was taken, so this correction was made in the text.

  1. The N-H name in Figure 3 appears several times. If this belongs to different types of bonds, please indicate them differently.

Regarding your comment, the N-H bond appears multiple times in Figure 3, indicating that the bond is the same but appears at different wavelengths due to different interactions. The author's goal is to highlight these bonds and their interactions.

  1. The authors are mentioning that “Release pattern data were shown as means ± standard deviation. Each treatment had 3 replicates. Statistical data analyses were performed using the student t-test.” but no numerical values and student t-test results are given in the manuscript.

Regarding your valuable comment, Tukey's test was performed instead of t-test so that the significance can be shown as letters on the curves of Figure 6 . 

We hope that these changes are satisfactory, however, if there is a need for further editing, we would be happy to make any additional changes that you suggest.

Best regards

- Statistical Analysis: The section on statistical analysis needs to be clearer and more detailed. Please provide additional context and methodology.
- Unit Conversion: Please convert the units from PSi to MPa for consistency with international standards.
- XRD Graphs: Include the indexing of the peaks in the XRD graphs to enhance clarity. 
- Standard Deviation: Provide the standard deviation for all data points in Figure 6 to give a better understanding of the variability in your results.
- Conclusion: The conclusion should be closely aligned with the results presented. Please ensure it includes specific values.
Thank you for your efforts, and I look forward to seeing the revised version.

Comments on the Quality of English Language

There are several typographical and grammatical errors in the text, the manuscript should be revised in terms of grammatical rules by a native English speaker. There is not sufficient cohesion and unity in the text, especially the abstract.

Round 2

Reviewer 1 Report

Comments and Suggestions for Authors

1.       Page 3, line 171: “Characterization fertilizer” is not clear. Please rephrase.

2.       No version of the SPSS software is given. Same remark for Excel.

3.       The SRU abbreviation stands for “Slow release urea” in the manuscript, ant not for “slow release urea fertilizer” as suggested by the authors (see page12, line 582 compared with page 13, line 644). Please be more consistent.

4.       Normalization of XRD patterns (as well as  FTIR spectra) is not related to the angle in which the XRD analysis was taken. Consequently, the question about how the normalization of these analyses was carried out is still under discussion.

5.       The authors added “a 8% water (8 mL)”, but no information about how is expressed that percentage (mass, mole, volume) is provided.

Regarding your valuable comment. the subtitle was corrected.

 

  1. No version of the SPSS software is given. Same remark for Excel.

Regarding your valuable comment. the version of softwares were added.

 

  1. The SRU abbreviation stands for “Slow release urea” in the manuscript, ant not for “slow release urea fertilizer” as suggested by the authors (see page12, line 582 compared with page 13, line 644). Please be more consistent.

Regarding your valuable comment. abbreviation of SRU was uniform throughout the text.

 

  1. Normalization of XRD patterns (as well as FTIR spectra) is not related to the angle in which the XRD analysis was taken. Consequently, the question about how the normalization of these analyses was carried out is still under discussion.

Thank you very much for your valuable comment. In order to draw the XRD and FTIR curves, we used the original data of the XRD and FTIR Instruments, so, no normalization was done. For clarity, the pdf diagrams that these instruments gave us have been attached.

 

  1. The authors added “a 8% water (8 mL)”, but no information about how is expressed that percentage (mass, mole, volume) is provided.

Regarding your valuable comment. the dimension of water percentage was expressed.
