Special Issue Information
Dear Colleagues,
A good knowledge of the soil chemistry status is of great interest regarding important topics such as soil fertility, contamination problems, eutrophication, acidification, and climate change. Lately, more advanced tools for assessing soil chemistry have been developed. These include X-ray absorption spectroscopy (XAS) for studying the speciation of nutrients (e.g., phosphourus and calcium) and potentially toxic elements (PTE) (metals and metalloids). New techniques that use the micro- and nanosized mapping of elements including synchrotron µ-XRF (microfocused X-ray fluorescence spectroscopy), which can show spatial distribution patterns in the soil and correlations of elements in space. Furthermore, this technique can be coupled with speciation methods such as µ-XAS and µ-XRD (X-ray diffraction). Another set of valuable tools for evaluating soil chemistry include geochemical models for speciation, solubility prediction, weathering, nutrient cycling, acidification, eutrophication, and the transport of elements.
Since soils often have a complex composition and can be highly heterogenous, it is seldom enough with only one technique for a full view, therefore studies with a combination of techniques are highly valuable.
The scope of this Special Issue is to highlight new, state-of-the-art research regarding these topics, in order to better evaluate the soil chemistry status of soils around the world.

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 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. Sustainability 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 2400 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.
