Special Issue Information

Dear Colleagues,

It is our pleasure to announce the launch of a second Special Issue of Agronomy focused on problematic heavy metals and metalloids in agriculture. Heavy metals belong to a very well-known group of environmental contaminants. The main sources of heavy metals entering agricultural ecosystems should be defined. The differences between the behavior of heavy metals from natural and anthropogenic sources should be described. The topic of extreme geogenic load of agricultural soils by some heavy metals continues to be particularly important today, and the use of agrochemicals and (in)organic soil amendments with potentially increased heavy metal contents is a serious problem in agriculture. The impact of industrial and traffic emission outputs on agricultural soils is also significant. The study of heavy metal behavior in a soil environment and mobility and transfer in plants, water, and other parts of the environment is needed. Heavy metal contents in eroded agricultural soils and extracted sediments from ponds and water reservoirs can change the quality of agricultural soils and the water environment. Heavy metals can strongly influence soil functions, water quality, food chain quality, and human health. The knowledge of possible risks connected with increased heavy metal contents in agriculture and the potential of remediation techniques focused on a reduction in risks following contamination will be a valuable contribution to this Special Issue.

This Agronomy Special Issue will welcome contributions in the field of interest, including sources of heavy metals in agriculture, problematic heavy metal monitoring and assessment, inputs and monitoring of heavy metals in food chains, risk assessment, possible tools for heavy metal contamination management in agriculture, and remediation techniques applicable in agriculture.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Zinc is essential for the growth and development of plants, but in excessive amounts in the soil it can be toxic for them. Its mobility depends in part on the organic matter content of the soil. The aim of the study was to investigate the effect of application of increasing amounts of zinc (200, 400 and 600 mg Zn·kg−1 of soil) together with various forms of organic fertilizer (cattle manure, chicken manure and spent mushroom substrate) on the yield of cocksfoot and the content and uptake of this metal, and to determine its bioaccumulation factor and tolerance indices. A minor effect of zinc on cocksfoot, expressed as a decrease in yield, was observed following the application of 400 mg Zn·kg−1 of soil. Increasing application to 600 mg Zn·kg−1 caused a significant decrease in yield. Application of 400 and 600 mg Zn·kg−1 of soil significantly reduced the value of the Zn/Org tolerance index. Increasing levels of zinc application increased its content and uptake by cocksfoot and reduced the bioaccumulation factor in the plants. All of the organic materials applied increased the yield of cocksfoot and its uptake of zinc. Spent mushroom substrate increased the Zn/Org tolerance index, while cattle manure and chicken manure increased the Org/Zn tolerance index, which confirms their protective action against high zinc content in the soil.
