Special Issue Information

Dear Colleagues,

As sustainable agriculture gains increasing importance in the face of growing environmental challenges and resource limitations, green chemistry is emerging as a central paradigm for developing safe, efficient, and environmentally responsible agricultural practices. One of the key strategies in this field involves the transformation and revalorization of agricultural and food processing by-products—not for nutritional use, but for their potential in reducing waste, enhancing soil quality, producing bio-based agrochemicals, and supporting closed-loop agricultural systems.

Innovative molecular tools and green chemical technologies are enabling the development of alternatives to conventional agro-inputs, such as synthetic fertilizers and pesticides; moreover, they are promoting precision applications that minimize ecological impact. These approaches align closely with the core principles of green chemistry, including waste minimization, the use of renewable feedstocks, and safer, cleaner production methods.

The aim of this Special Issue is to showcase recent research and advances in the application of green chemistry and molecular strategies in agriculture. We welcome interdisciplinary contributions that explore innovative uses of agri-food by-products as bioresources, as well as approaches that improve environmental performance, safety, and sustainability by reducing reliance on synthetic agrochemicals and enhancing the biological potential of natural compounds.

Topics of interest include the following:

  • Natural bioactive compounds in biopreparations and their environmentally friendly synthesis.
  • Innovative delivery systems for active substances (e.g., nanocarriers, microcapsules).
  • Biofertilizers, biostimulants, and plant growth regulators, especially their influence on crop quality and productivity.
  • Natural compounds enhancing plant immunity and development, as well as their molecular mechanisms of action.
  • Analytical and diagnostic methods supporting green agricultural practices.
  • Biosensors, chemometrics, and spectroscopy for detecting substances in plants, soil, and water.
  • Environmental analysis of agrochemical residues.
  • Molecular tools (genomics, proteomics, metabolomics) for studying plant–environment interactions.
  • Alternative fertilization strategies and food safety in sustainable systems.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules 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.

For many years, deficiencies in selenium (Se) and, sometimes, sulphur (S) have been observed in populations in most European countries and other parts of the world. This study aimed to determine the effect of selenium (0, 10 and 20 g Se ha−1) and the date of its application (in the tillering phase—BBCH 22–24 and in the stem elongation phase—BBCH 31–34) and sulphur application (0, 15 and 30 kg S ha−1) on the content of various forms of nitrogen (total nitrogen, protein nitrogen, ammonium nitrogen, and nitrate nitrogen) in winter spelt wheat and winter common wheat. Selenium application influenced nitrogen distribution in wheat. In spelt, grain total-N decreased by 4%, while common wheat straw increased by 13%. Application timing had no significant effect on total-N. Sulphur slightly raised total-N in common wheat grain and straw. Selenium reduced protein-N in spelt grain by 7% but increased it in common wheat straw by 18%. Ammonium-N in straw rose by 24–27%, while nitrate-N declined in grain and straw of both species. Sulphur-enhanced mineral N forms (ammonium-N by 6–16%, nitrate-N by 7–24%), especially in the early stages. Se–S fertilization strategies should consider their competitive uptake and impact on N metabolism. Full article
