Water–Salt in Farmland: Dynamics, Regulation and Equilibrium

Dear Colleagues,

Against the backdrop of intensifying global climate change and dwindling freshwater resources, soil salinization in agricultural lands has emerged as a critical challenge, jeopardizing global food security and agricultural sustainability. Investigations into the dynamics, regulation, and equilibrium of water–salt interactions in farmland ecosystems not only facilitate the safe utilization of saline water and the remediation of saline-alkali soils, but also effectively mitigate secondary salinization in irrigation districts, enhance land quality, safeguard ecological security, and carry substantial strategic significance for achieving the United Nations Sustainable Development Goals (SDGs).

This Special Issue will focus on the following key research areas: improvement of saline-alkali land and utilization of saline water irrigation; mechanisms of soil water–salt transport and regulation strategies; analysis of water–salt balance and response mechanisms to salt stress; and crop salt-tolerance characteristics the and cultivation of halophytes. It will also cover studies on the applications of exogenous substances in the enhancement of crop salt/drought resistance, mitigating salt stress, optimizing soil environment, and improving soil quality. Furthermore, we welcome contributions on large-scale (e.g., irrigation districts, watersheds) water–salt regulation and balance methods, as well as intelligent monitoring technologies for soil–crop water–salt status that employ techniques such as UAV-based remote sensing inversion.

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. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.
