Special Issue Information

Dear Colleagues,

Geochemical processes and interactions that take place in soils play an essential role in regulating the fate and transport of nutrients and contaminants. Geochemical processes also control the stability and bioavailability of nutrients and contaminants that affect the yield and safety of agricultural products and almost every living thing in the soil ecosystem. Thus, the systematic integration of knowledge about the geochemical processes of nutrients and contaminants in soils, from atomic to global scales and from short-term to long-term, is critical for the sustainability of agriculture and the environment. Understanding these fundamental geochemical processes will also help us in implementing the appropriate strategies to reduce nutrient and contaminant loss, and to increase nutrient bioavailability.

The aim of this Special Issue is to highlight research, at multiple scales, on geochemical processes that regulate the fate and transport of nutrients and contaminants in soil ecosystems. In this Special Issue, original research articles, short communications, and reviews are welcome. Research areas may include (but are not limited to) the following: critical geochemical processes of nutrients (e.g., C, N, and P), abiotic or mineral-assisted degradation of organic contaminants, transport and transformation of heavy metals on mineral–water interfaces, soil mineralogy, and the modeling of large-scale cycles.

I look forward to receiving your contributions.

Dr. Hui Li

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).

Ecological characteristics are very important for the Earth’s environment and human lives. Recently, more attention has been paid to the ecological problems in the world. The soil and its parent materials/rocks serve as the supporting materials for the ecological system on the Earth’s surface. The ecological characteristics in one region are associated with or even dependent on the soil-forming process. Thus, the study of the weathering process of parent materials/rocks is important for our understanding of the geological genesis of ecological problems. In this study, three typical ecological problems in China are introduced: land salinization in the north, the desertification of land in the northwest, and Karst rocky desertification in the south. We chose 23 typical profiles for observation and sampling. The soil-forming processes in these areas were investigated by geochemical research, and eco-geology models were subsequently established to explain the profound relationship between vegetation cover and the soil-forming process. Our work first focuses on the geochemical methods used to explore these ecological issues, emphasizing the contribution of the geological genesis to the ecological characteristics. Using geochemical methods, such as the chemical index of alteration (CIA), major element and trace element distribution characteristics, the formation processes, and characteristics of bedrock-weathering soils under diverse epigenetic geological settings were determined. Eco-geology models were then developed by evaluating the vertical structure and material composition of soil, the characteristics of elemental migration during soil formation, and the enrichment and loss of elements in the supporting layers and their repercussions.
