Title: Status and influential factors of soil nutrients and acidification in Chinese tea plantations

This paper systematically analyzes the contents of organic matter (SOM), nitrogen (N), potassium (K), phosphorus (P), and pH levels in tea plantation soils. It explores the spatial variations and influencing factors, offering suggestions for mitigating soil acidification and recommending potassium fertilizer application strategies for tea plantations in southern and/or high-altitude regions to support sustainable management. The article has a clear structure, detailed data, and comprehensive analysis, making it highly valuable academically and practically. However, during the review process, I believe the following aspects need further improvement:

1. The title should be revised to "Status and Influential Factors of Soil Nutrients and Acidification in Chinese Tea Plantations: A Meta-Analysis," as it is based on data from literature searches.
2. All major figures should not be placed in the appendix, especially those representing national-level meta-analyses of tea research; additionally, some tables could be selected as supplementary tables.
3. The format of all tables needs to be modified and adjusted.
4. The second and third paragraphs of the Introduction discussing the research progress on pH and nutrients can be improved—either merged into one paragraph or separated into distinct sections.
5. The arrangement of figures and text in the Results section needs to be organized properly, such as in Table 6.
6. Section 4.1 in the Discussion is overly lengthy; I recommend streamlining the language.
7. It would be beneficial to include a section on the limitations of this study.
8. In-depth research on mechanisms: While the article highlights various environmental factors and management practices affecting tea plantation soils, further investigation into the specific mechanisms and pathways of these influences is necessary. For instance, research should focus on how different fertilizer amounts and application methods impact the dynamic changes in soil nutrients.

Wang et al. reviewed the status and influential factors of soil nutrients and acidification in Chinese tea plantations. Overall, this is an interesting and useful study. The methods employed for data collection and analysis are robust. I have a few comments that may enhance the quality of the paper.

Major comments

1. The authors propose several effective management practices. However, there are trade-offs between fine management and costs. I strongly recommend conducting a brief economic analysis, or at the very least, including a discussion on whether the benefits of these practices outweigh the associated costs.

2. Please improve the English language and expression.

Minor comments

L16: Please specify why you use data pairs. What are the two components that you are comparing?

L19: What is the difference bewteen geolocation and location?

L20: Please specify how you calculated the stoichiometric ratios, e.g., C:N, C:P...

L21: Perhaps consider deleting "life"?

L52: soil pH rather than soil pHs.

L108: This is printed in Chinese. For the soil tpes mentioned in this study, could you please add a brief comparison table of the Chinese classification and the international classification, e.g., WRB?

L. 130: Is there a composite index that assigns different weights to various indicators?

L220: Large C stock does not necessarily mean a large C sequestration capacity. This does not make sense. Please delete. 

L250: Please specify in what context did Yan et al., (2020) reported the value 4.68.

L261: I suggest checking the soil parent material. Is it possible that carbonate rocks contributed to the high pH values?
