Special Issue Information
Dear colleagues,
During the last decades, both liquid and solid-state NMR spectroscopy in one and multiple dimension have been accepted as a powerful tool for the analysis of soil organic matter (SOM) and its alteration with changing environmental conditions. As further developments, nuclear magnetic resonance imaging (MRI) and fast field cycling (FFC) NMR relaxometry, high resolution magic angle spinning (HR-MAS) NMR or dynamic nuclear polarization (DNP) NMR expanded considerably the selection of available NMR-based tools. Formerly discussed as highly innovative, some of those techniques turned into tools that nowadays are almost routinely applied, although their full potential for studying processes in soil is still only scarcely recognized. This can be explained by problems related to spectral resolution and sensitivity caused by the heterogeneous nature of soil-related material but also by the fact that many soil scientists are not aware that the technical improvements and the continuous developments of specialized and pulse techniques opened the door for new analytical approaches, which previously were not even feasible. In order to fill this gap, experienced NMR spectroscopists, working in the area of soil and environmental sciences as well as soil scientists applying these techniques, are invited to contribute to this special issue. The intention of this issue is to provide not only an introduction of the respective techniques to interested readers, but also to give examples of their successful application.

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. Agronomy 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 2600 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.
