Special Issue Information

Dear Colleagues,

The agro-environment is usually maintained through the production of food on cropland, which is a very important factor decreasing organic and inorganic sources of macro-and micronutrients for crop growth in agro-ecosystems. This agro-environmental impact is mainly related to agricultural supplies such as fertilizers, pesticides, irrigation water, and mulching vinyl, which affect crop growth, water and soil contamination, and greenhouse gas emissions (and thus climate change). The issues of fine particulate matter and micro-plastic particles are also urgent research themes regarding the agricultural sector.

The assessment of the agricultural eco-system is critical for optimizing agricultural practices in rural areas. Relevant sustainable agricultural practices for reducing non-point pollutants and maintaining a healthy agricultural environment are related to the keywords below.

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. Sustainability 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 2400 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.

Exogenous Salicylic Acid Alleviates Freeze-Thaw Injury of Cabbage (Brassica oleracea L.) Leaves
by Kyungwon Min and Sang-Ryong Lee
Sustainability 2021, 13(20), 11437; https://0-doi-org.brum.beds.ac.uk/10.3390/su132011437 - 16 Oct 2021

Abstract
Freezing tolerance and physiological/biochemical changes were investigated for cabbage (Brassica oleracea L. ‘Myeong-Sung’) leaves treated with 0.5 mM salicylic acid (SA) by sub-irrigation. SA treatment did not interfere with leaf-growth (fresh/dry weight, and leaf-area), rather promoted growth (leaf-area) as compared to the [...] Read more.
Freezing tolerance and physiological/biochemical changes were investigated for cabbage (Brassica oleracea L. ‘Myeong-Sung’) leaves treated with 0.5 mM salicylic acid (SA) by sub-irrigation. SA treatment did not interfere with leaf-growth (fresh/dry weight, and leaf-area), rather promoted growth (leaf-area) as compared to the control. Temperature-controlled, laboratory-based freeze-thaw assays revealed that SA-treated leaves were more freeze-tolerant than controls as evident by less ion-leakage as well as malondialdehyde content after freeze-thaw stress treatments (−2.5 and −3.5 °C). SA treatment also significantly alleviated freeze-induced oxidative stress as evidenced by the lower accumulation of O2•− and H2O2, concomitant with higher activities of antioxidant enzymes (ascorbate peroxidase and superoxide dismutase) relative to the control. Specifically, SA-treated leaves had a greater abundance of compatible solute (proline) and secondary metabolites (phenolic/flavonoid contents). These changes, together, may improve freezing tolerance through protecting membranes against freeze-desiccation and mitigating freeze-induced oxidative stress. Full article

The production of volatile fatty acids (VFAs) from waste stream has been recently getting attention as a cost-effective and environmentally friendly approach in mechanical–biological treatment plants. This is the first study to explore the use of a functional bacterium, AM5 isolated from forest soil, which is capable of enhancing the production of VFAs in the presence of soil bacteria as a co-digester in non-strict anaerobic fermentation processes of food waste leachates. Batch laboratory-scale trials were conducted under thermophilic conditions at 55 °C and different pH values ranging from approximately 5 to 11, as well as under uncontrolled pH for 15 days. Total solid content (TS) and volatile solid content (VS) were observed with 58.42% and 65.17% removal, respectively. An effluent with a VFA concentration of up to 33,849 mg/L (2365.57 mg/g VS; 2244.45 mg/g chemical oxygen demand (COD)-VFA VS; 1249 mg/g VSremoved) was obtained at pH 10.5 on the second day of the batch culture. The pH resulted in a significant effect on VFA concentration and composition at various values. Additionally, all types of VFAs were produced under pH no-adjustment (approximately 5) and at pH 10.5. This research might lead to interesting questions and ideas for further studies on the complex metabolic pathways of microbial communities in the mixture of a soil solution and food waste leachate.
