Analysis of Nitrogen Uptake in Winter Wheat Using Sensor and Satellite Data for Site-Specific Fertilization

Round 1

Reviewer 1 Report

The work entitled "Determination of nitrogen uptake by winter wheat using sensor and satellite data for site-specific fertilization" concerns two basic non-contact measurement methods (sensor and satellite) which were studied in winter wheat and their precision. It was very well stated that this study is acceptable with a slight revision and suitable for publication in this journal. The manuscript is clearly and intelligible. The results are interesting and can be used in further work. I'm agree with the author that other literature also presented good results using satellite date. Despite minor editorial and linguistic improvements, the manuscript may be acceptable for the journal.

Dear Reviewer 1,

first of all, thank you for your comments. I have made a slight revision and incorporated all the editorial improvements. 

Reviewer 2 Report

Please find in the following my comments about the review of a manuscript under the title (Determination of Nitrogen Uptake in Winter Wheat Using Sensor and Satellite Data for Site-Specific Fertilization):

In this study, the authors investigated two basic noncontact measurement methods (sensor and satellite) in winter wheat, and their precision is evaluated

Main question addressed by the research

This study focused on the examination of the accuracy of recording the nitrogen uptake of two basic non-contact measurement methods of site-specific nitrogen fertilization in winter wheat.
