Special Issue Information

Dear Colleagues,

The presence of nanomaterials in soil has become an unavoidable issue, so it is worth conducting in-depth research on their effects on crops (plants), soil quality, and soil microorganisms to understand whether they are beneficial or harmful to plant production. It is also important to balance the advantages and disadvantages of nanomaterials. Nanoagriculture is currently a popular research topic, as are the development, effectiveness, and potential risks of nanofertilizers and nanopesticides. This Special Issue is dedicated to studying the impact and utilization effects of nanomaterials on plant production with the aim of addressing their sustainable development within 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. Plants 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 2700 CHF (Swiss Francs).

Lead (Pb) in soil poses serious environmental and health risks, and its removal requires complex and costly treatment methods to meet strict regulatory standards. To effectively address this challenge, innovative and efficient techniques are essential. Sepiolite-supported MnFe2O4 (MnFe2O4/SEP) composites were synthesized via a chemical co-precipitation method. The effects of MnFe2O4/SEP on soil pH, cation exchange capacity (CEC), available Pb content, Pb2+ uptake, and the activities of antioxidant enzymes in Brassica chinensis (Pak Choi) were examined. MnFe2O4/SEP showed superior Pb2+ adsorption compared to SEP alone, fitting Langmuir models, Dubinin-Radushkevich (D-R) models, Temkin models and pseudo-second-order kinetics. The maximum adsorption capacities at 298, 308, and 318 K were 459, 500 and 549 mg·g−1, respectively. XPS analysis indicated that chemisorption achieved through ion exchange between Pb2+ and H+ was the main mechanism. MnFe2O4/SEP increased the soil pH by 0.2–1.5 units and CEC by 18–47%, while reducing available Pb by 12–83%. After treatment with MnFe2O4/SEP, acid-extractable and reducible Pb in the soil decreased by 14% and 39%, while oxidizable and residual Pb increased by 26% and 21%, respectively. In Brassica chinensis, MnFe2O4/SEP reduced Pb2+ uptake by 76%, increased chlorophyll content by 36%, and decreased malondialdehyde (MDA) levels by 36%. The activities of antioxidant enzymes—superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT)—were decreased by 29%, 38% and 17%, respectively. These findings demonstrate that MnFe2O4/SEP is an efficient Pb2+ adsorbent that immobilizes Pb in soil mainly through ion exchange, thereby providing a highly effective strategy for remediating Pb-contaminated soils and improving plant health.

Due to the environmental concerns surrounding widely used antimicrobial agents, the use of nanotechnology to suppress crop diseases has attracted increasing attention in the agricultural field. This paper investigated the inhibitory effects of manganese-based nanomaterials (NMs) on rice leaf blight. In vitro experiments showed that manganese oxide (MnO2) NMs and manganese tetroxide (Mn3O4) NMs directly inhibited Xanthomonas oryzae (Xoo) with a maximum OD value of 0.177, which was 11.5% lower than the control. In vivo experiments demonstrated that spraying MnO2 NMs and Mn3O4 NMs reduced the diseased leaf length to 22–28% and 25–26%, respectively. This is due to Mn-based NMs inducing enhanced plant resistance by increasing the activity of phenylalanine ammonia–lyase in rice leaves by 36–61%. Single particle inductively coupled plasma mass spectrometry showed that Mn3O4 NMs are more frequently retained as NMs in rice than MnO2 NMs, resulting in enhanced antimicrobial effects. Mn-based NMs exhibit strong antimicrobial activity and hold significant promise as alternatives for plant protection and agricultural applications; however, careful consideration must be given to their concentrations and application methods.
