Short-Term Effects of Bio-Organic Fertilizer on Soil Fertility and Bacterial Community Composition in Tea Plantation Soils

Round 1

Reviewer 1 Report

General comment:

In this paper, in order to study the effects of bio-organic fertilizer application on the soil of tea plantation, the effects of BOF on soil fertility and bacterial community of tea gardens and the effects of tea leaf biomass were further explored through three-year potting experiments. It was found that the application of BOF in potting experiments improved soil fertility and soil bacterial function and increased tea plant biomass. It’s suggested that more detailed data should be introduced to make some viewpoints more convincing through the manuscript.

 

Specific comments:

1.        Line 39: The sentence is not smooth, what is the relationship between the application of fertilizer as a beverage and fertilizer?

2.        Line43: Replace "Therefore" with "However". The harm caused by chemical fertilizers has been mentioned above, and the following should be turned to whether the advantages of organic fertilizers are better.

3.        Line47: What are the risks of contamination of organic fertilizers of animal origin, what studies illustrate, and give relevant examples.

4.        Line49: After the application of BOF, the improvement of soil is given as an example of the corresponding article, about three. Make the application of BOF more convincing.

5.        Line54: How to influence soil bacterial communities; The influencing factors are those; Specific bacterial communities; Thus, how to affect plant growth. It must be supported by discussing relevant data.

6.        Line62: The important role of rhizosphere microorganisms in plant growth is mentioned at the beginning, and the relevant examples of plant growth are not mentioned throughout the paragraph.

7.        Line74: An effect on tea root bacterial communities at low pH was proposed. The effects of other pH on bacterial communities are given as corresponding examples, highlighting the significance of low pH research in this paper.

8.        Line96: The physicochemical properties of soil are listed in the table as better.

9.        Line194: Comments can be expressed in more detail, simply indicating the corresponding treatment of each letter.

10.    Line197: In the results, critical results should be included.

11.    Line234: The supplemental figure gives the name, comment. There is only one diagram alone without comments.

12.    Line238: The elemental flora in the soil has a significant impact, how it is affected, and whether it increases or decreases are not clearly indicated.

13.    Line342: The sentences are not smooth.

14.    Line363: Give examples of soil nutrients and pH.

15.    Line365: At the beginning, it was mentioned that BOF have a significant positive effect on inhibiting pathogenic bacteria, and there is no mention of related examples and how to affect them.

Reviewer 2 Report

The paper of Hu et al. is aimed at studying the effect of organic fertilization in soil fertility, the biomass of tea plantations and change of associated microbiome. In my opinion, the paper is well written and scientifically well organized, I found only some minor issue reported below:
Line 96. add “color” before “yellow brown”
Line 158. Please replace “And otutab….” with “The otutab….”
Line 180 please replace “none BOF……..” with “no BOF….”
Line 249. Please change “function” with “functional”
Line 312. Soil fertility results are reported in fig. 2 not fig 1. Please correct.
Line 338 “verified” may be better to use “confirmed”
