Special Issue Information

Dear Colleagues,

Agricultural plastics are important implements for the productivity, profitability, and sustainability of vegetables and other specialty crop production systems. Mulch films, low and high tunnels, silage films, and other plastic materials help increase crop production by controlling the cultivation environment, extending the growing season, preventing weeds, and reducing the use of irrigation water, fertilizer, and other inputs. However, increased plastic use has led to the stockpiling of poorly biodegradable conventional plastics such as polyethylene on farms or other improper disposal, which leads to the formation of microplastics that can induce “plastic pollution” in soil and nearby waterways, having a negative impact on soil health and water quality, thereby posing a threat to food production systems. Even the employment of biodegradable plastics, particularly in mulch films, which provides more sustainable plastic disposal options (biodegradation in soil or by composting), produces microplastics that can reside for several months.

This Special Issue aims to highlight the current state of the art of agricultural plastics. We welcome research, perspectives, and review articles pertaining to agricultural plastics: new products and applications, improved best practices for their deployment and disposal, the upcycling of plastics after the completion of their service life, and their impacts on agricultural ecosystems and farmers.

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. Agriculture 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.

The risks brought by microplastics (MPs) to agricultural soil structure and crop growth in the agricultural system are the focus of global debate. MPs enter the soil through various routes, such as through the use of agricultural mulch and atmospheric deposition. Here, we review the research on MP pollution in the soil during the last 30 years. This review focuses on (i) the sources, types, and distribution characteristics of MPs in agricultural soils; (ii) the migration and transformation of MPs and their interactions with microorganisms, organic matter, and contaminants in agricultural soils; and (iii) the effects of environmental factors on the composition and structure of MPs in agricultural soils. This review also proposes key directions for the future research and management of MPs in the agricultural soil. We aim to provide a theoretical basis for the fine management of agricultural farmland. Full article
