Review Reports

Round 1

Reviewer 1 Report

• The introduction should be placed more continuously and not have so many sub-chapters.
• In the introduction, the themes should be more connected. The same is true of the rest of the text.
• Correction of typing errors is recommended.
• The work should be further developed. More work should be done in particular on the discussion and conclusions 
• The justification for pollution caused by the tractor versus manual labor should be further developed, namely at the opportunity cost of the work of small farmers.

Reviewer 2 Report

The research is interesting and maybe relevant to specific geography but the manuscript needs more detailed statistical analysis and quality discussion.
