Special Issue Information
Dear Colleagues,
Heavy metal (HM) contamination in agricultural soils has emerged as a global environmental and food safety concern over the past several decades. Anthropogenic activities such as mining, smelting, industrial effluents, improper waste disposal, and excessive application of agrochemicals have led to widespread accumulation of HM (e.g., Cd, Pb, As, Hg) in soil systems. Historically, research focused on total metal concentrations; however, it is now recognized that bioavailability, speciation, and complex interactions within the soil–plant continuum determine actual crop uptake and human exposure. Specifically, the migration and transfer of HM in soil-pore water and rhizosphere micro-interfaces are determining factors for crop accumulation of HM and its human exposure. The Special Issue aims to explore the mechanisms concerning HM migration in soil and rhizosphere transfer into plants, as well as the development of HM passivation, foliar fertilization and other technologies to regulate HM uptake by plants, in order to realize safety agricultural production and farmland quality improvement.

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 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 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.
