Special Issue Information

Dear Colleagues,

Humus is a stable natural product of the joint evolution of living and nonliving matter. It is formed as a result of repeated transformation of plant and animal remains in the presence of minerals under the influence of biological, climatic, and geological factors for a long time. Humus is not just a specific product of biological waste disposal, but also an important soil component. In particular, it acts as a stabilizer of the physical and chemical state of soils. Moreover, it acts as a source and regulator of the supply of nutrients to plants and soil organisms while also serving as their habitat.

Humus, being a complex composite material, contains both organic (mainly) and inorganic substances. From the point of view of chemistry, humus is a dissipative supramolecular system of polymolecular assemblies characterized by nonstoichiometric elemental composition, polydisperse distribution of molecular weights, irregular structure, and heterogeneity of structural units.

Studying such a complex object is a daunting task for researchers of a wide variety of specializations. This is a challenge from nature itself for humankind, which already knows a lot about the structure of distant galaxies and "close" viruses but has not made much progress in studying what is literally under its feet and what has been "feeding" it for millions of years. All the more interesting is the theme of our Special Issue: "Research Progress on Extraction and Characterization of Humus". In this issue, we would like to consider the latest data on new methods of isolation and separation of humus components, as well as the use of modern research technologies for the characterization of humus; its fractions, including humin and humic substances (humic and fulvic acids); and related materials (e.g., lignohumates, biochar).

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 papers will be 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 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 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. Separations is an international peer-reviewed open access monthly 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 1800 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.
