Nitrogen Deposition May Benefit to Larix olgensis Root Soils
Round 1
Reviewer 1 Report
Dear Authors,
The manuscript “Nitrogen deposition may benefit to Larix olgensis root soils” is an interesting paper for readers about the change in soil physio-chemical properties, and microbial community structure of forest changes under addition of nitrogen. Please consider some point as belove:
- The manuscript mentioned physical and chemical soil properties. However, study just determined soil pH, moisture, NH4+, NO3-, TN, TC, TP,… not physical properties. “Physical” must be removed from the manuscript.
- In experiment area and design part: manuscript mentions “there were five treatments in the experiment”: how many in fact?
- In method: there is no reference for methods for analysing chemical properties. Authors have to cite references.
- Explain what are: CK, HN, LN, MBC, MBN,… to leaders for easily following.
- In result part: “Nitrogen deficiency limits the productivity of L. olgensis forests, and the nitrogen addition treatment alleviated this limitation to some extent by promoting plant growth, and plants promoted the uptake of total soil carbon content, leading to a decrease in TC content”: how plants can uptake total soil carbon content? The explanation could not be accepted here.

Reviewer 2 Report
Congratulations to the authors for this research.
The main question addressed by the research is soil and grass condition and use.
The subject is partially original and the subject covered was found to be appropriate for the field, I think it offers practical information and results compared to other publications.
As for the methodology authors should take the following views into consideration.
Why nitrogen application was made in October. It is understood that the average amount of precipitation in the region is around 570 mm. Nitrogen given in October is likely to be washed away. That's why this application was not done in April, May, June.
Samples were taken from 10 cm. Why is this depth not 20,30,40 cm?
There is a first soil analysis of the application area. Research results need to be compared with this initial analysis.
The results are consistent with the evidence and arguments presented.
References are appropriate.
