Remote Sensing for Precision Nitrogen Management

Dear Colleagues,

Nitrogen is the most widely used macro nutrient in the world. Agriculture is a major source of N₂O emissions in the biosphere. Precision nitrogen management is an important area of advanced nutrient management as well as precision agriculture for solving problems in food and environmental security for sustainable agricultural and social development. Precision nitrogen management aims to match nitrogen supply with crop N demand in both space and time to ensure high crop yield while increasing N use efficiency and protecting the environment. It is a research area that involves management zone delineation, proximal and remote sensing, crop growth modeling, spatial statistics, variable rate technology, agronomy, soil science, meteorology, plant nutrition and greenhouse gas emission mitigation, etc.

Remote sensing is one of the key supporting technologies for precision agriculture, and advances of proximal and remote sensing technologies have greatly contributed to the development of precision nitrogen management. To help readers keep up with the progresses on the applications of proximal canopy sensors, UAV-based remote sensing, aerial remote sensing and satellite remote sensing in precision nitrogen management of cereal crops, vegetables and fruit trees, etc., we would like to invite you to submit research and review papers on the following topics:

• Proximal and remote sensing-based non-destructive diagnosis of crop nitrogen status
• Proximal and remote sensing-based in-season variable rate nitrogen recommendation algorithms and precision management strategies
• Remote sensing-based site-specific management zone delineation and evaluation for precision nitrogen management
• Simultaneous diagnosis of crop nitrogen stress and other stress factors (other nutrients, water, disease, insect damage, etc.)
• Combining remote sensing and crop growth modeling for precision nitrogen management
• Data fusion of sensing and other related data for precision nitrogen management
• Integration of sensing technology-based precision nitrogen management with other high yield crop management technologies
• Evaluation of sensing technology-based precision nitrogen and crop management strategies using field experiments and on-farm trials
• New sensing technologies for precision nitrogen management

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
