Reviewer 3 Report

Dear Authors,

Despite all advantages of the research performed, the manuscript text contains several important shortcomings, and they should be eliminated.

A huge number of typos mistakes in the manuscript. Please, check all the text very attentively and carefully.

Some corrections have to be made in the lines: 37, 52, 66 (cculky na nac ? What it is ?), 126, 129, 155, 159, 160, 166, 168… title of figure 5, etc.

Section 2.2: the phrase “we collected” was used too frequently. Please replace ‘to collect’ by synonyms (to pick, gather…).

Table 2, 3 and 4: some obtained values have to be expressed with dots (not comas).

Citations of references 20 and 21 were missed in the text.

You are claiming that the aim of this work was to characterize structural and chemical composition of suspended soils of South Vietnam. For this reason it will be very important to know conductivity (µS/cm) of the soils and main inorganic composition (amounts of Ca, Mg, K, Na, Al, Mo, Mn, Cu, Fe, Zn, Ni, P.. and concentrations of some hazardous and heavy metals, such as Cd, Cr, Pb) in the investigated soil material. These parameters are very important for characterisation of the soils.

Please, check a reference list attentively.

Please, check a reference list attentively. – Corrected, but we were not able to measure resistivity on the height due to technical reasons, soil chemistry data has been amended

 

Reviewer 4 Report

Dear authors,

The topic is interested and ecologically is high important specially in specific ecosystems. However, there are some comments that should be considered before publishing such as:

The abstract should be rewritten because it seems like an abstract of review not research paper

There is a missed full stop in line 37

Please convert the units into SI unit such as Mg ha-1 and kg ha-1

More details are needed in the material and methods specially for the equipments and the methods used to determine N, C, O and H

In table 3, please convert the % into g kg-1 and put the significance letters in the table

Deep discussion is needed specially in section 3.1 and the first part of section 3.2

The paper should be supported by recent references from 2020 till now

There is a missed full stop in line 37 – corrected.

Please convert the units into SI unit such as Mg ha-1 and kg ha-1 - corrected

More details are needed in the material and methods specially for the equipments and the methods used to determine N, C, O and H – has been detalized.

In table 3, please convert the % into g kg-1 and put the significance letters in the table – here we are disagree, g kg-1 is typical for bulk samples of soil, but according to recommendation of International Humic Substances the elementary composition of humic substances normally is presented in percentages (e.g. https://humic-substances.org/elemental-compositions-and-stable-isotopic-ratios-of-ihss-samples/)

Deep discussion is needed specially in section 3.1 and the first part of section - Done

The paper should be supported by recent references from 2020 till – few references has been added.

 

Round 2

Reviewer 3 Report

Dear Authors,

English language and style still required minor corrections.

Dear reviwer! 

thank you, english has been improved

 

Dear Authors,

English language and style still required minor corrections.

Reviewer 4 Report

There are two comments still need to be responded: changing % in table 3 to units such as g kg-1 as well changing my/kg to mg kg-1 through the manuscript

 

 

 

 

 

 

Author Response

Dear reviewer, we agree that you usually need to follow the SI system of units, but in this case we followed the recommendations of the International Humic Substances Society  in order to make the results comparable

Thank you, you comment is very usefull if one will recalculate to balance of humic acids stock in whole ecosystems

we have added comment to 

table footnote:

* Data on elementary composition of humic acids are provided in percentages according to recommendation of International humic substances society). (https://humic-substances.org/elemental-compositions-and-stable-isotopic-ratios-of-ihss-samples/). For recalculation to g kg-1 in SI units one can multiply percentages values by 10.
