Special Issue Information

Dear Colleagues,

The low agronomic efficiency of N for several agricultural systems is a crucial point for sustainable agriculture.

Agronomic N-use efficiency is also the basis for economic and environmental efficiency. A high N input combined with a low efficiency results in environmental problems, such as pollution of groundwater due to nitrate leaching, and emission of ammonia and greenhouse gases from the plant-available N-pool.

Therefore, there is a need for agro-ecosystems that are profitable, but at the same time ecologically and socially sustainable.

To achieve a higher agronomic N-use efficiency, N supply should match N demand both in time and space, not for single crops but for a complex crop rotation, including cover crops, as an integrated system. To this end, diagnostic tools are available assessing N-status of growing crops, and N stabilizers and controlled release fertilizers can be used to synchronize release of N from fertilizer with crop needs.

This special issue brings together the current research findings dealing with all aspects of the understanding of agronomic efficiency of N in different agro-ecosystems, and the economic returns from adoption of best management practices such as those of conservative agriculture and organic farming.

Improving N efficiency is a fundamental challenge for sustainable agricultural production of horticultural, industrial and cereal crops.

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed Open Access quarterly 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 300 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Keywords

  • nitrogen sources and management strategies in low-input and organic farming systems
  • the role of cropping systems and tillage methods on N use efficiency in horticultural, industrial and cereal crops
  • decreasing environmental N losses and increasing the productivity in soil-plant systems, by tailoring applications of fertilizer N to site-specific conditions
  • rotations and cover crops as an integrated system to improve N management in sustainable agriculture
