“…The change of soil microenvironment caused by plastic film mulching performs significant effect on crop growth. An increasing number of researches reveal that both biodegradable film and ordinary plastic film mulching could improve soil water temperature environment during crop growth period, and significantly improve crop agronomic traits such as stem diameter, plant height and leaf area index(Li et al 2021 ; Ren et al 2022 ; Yang and Gao 2022 ). In accordance with previous reports, our data suggested when compared with CK2 treatment, the film mulching treatments could significantly promote the growth of taro; meanwhile, the effect of ordinary plastic film mulching on the morphological characteristics of taro plants was significantly higher than that of three biodegradable films.…”

This study investigated the degradation characteristics of different biodegradable film and its effects on soil nutrients in tillage layer, growth and development of taro and yield formation. Field experiment with biodegradable films, including poly-(butylene adipate-co-butylene terephthalate) PBAT, (poly-carbon dioxide) PCO2, (poly propylene carbonate) PPC, as well as common mulch film (CK1) and uncovered mulch film (CK2) were conducted on Longxiang taro in 2020 and 2021 respectively. The degradation rate of the three biodegradable films was PBAT > PPC > PCO2. Compared with CK1, the alkali-hydrolyzed N of PBAT at the growth stage and fruiting stage significantly increased in 2020 and 2021, respectively (both, P < 0.05). The average content of available P of PPC at seedling stage was higher than that in PCO2, and CK1 was significantly decreased compared with that in CK2 (all, P < 0.05). The content of soil available K and organic matter in different growth stages of taro in all film mulching treatments were decreased in comparison to CK2. Moreover, compared with CK2, PCO2 biodegradable film significantly increased plant height at seedling and growth stage, stem diameter at growth stage, and leaf area index at fruiting stage (all, P < 0.05). Similarly, the yield of mother and filial bulbs of PPC, PCO2 and PBAT were significantly higher than those of CK2 in 2020 and 2021, respectively (all, P < 0.05). However, no significant differences were found in starch, polysaccharide and protein contents among different treatments. The three biodegradable films, especially PCO2, can significantly affect soil nutrient content, promote plant growth and improve taro yield.

“…Melatonin helps plants cope with abiotic stresses to a large extent. For example, it has recently been discovered that exogenous melatonin application in wheat reduces root uptake and subsequent translocation to the shoot of NPs with the regulation of gene expression in aquaporins through upregulation both in roots and leaves (Li et al, 2021a , b , c , d ). Melatonin induced ROS scavenging to improve redox homeostasis and increased plant tolerance to MPs/NPs toxicity.…”

“…Additionally, alterations in soil properties also indirectly affect plant growth. Specifically, MPs/NPs can rupture the soil structure, diminish the permeation of rainwater as well as irrigation water, negatively affect the water holding capacity of the soil, disturb microbial activity in the soil, cause pH imbalance, and disrupt nutrient transfer (Cao et al, 2017 ; Li et al, 2021a , b , c , d ; Liu et al, 2018 ). MPs/NPs with smaller sizes and larger specific areas interact with soil microbiomes, reduce their normal growth and function, and interrupt nutrient dynamics in soils (Torres et al, 2021 ).…”

“…However, regarding mitigation of MPs/NPs pollution, biodegradation of soil plastic particles can be an effective way to alleviate the intensity of contamination in terrestrial lands (Sun et al, 2022 ). In the case of direct implementation, the exogenous application of melatonin in crops reduced both uptake and translocation of NPs by crop roots and shoots respectively, which boosted the tolerance of plants towards MPs/NPs toxicity (Li et al, 2021a , b , c , d ).…”

The toxic impact of microplastics/nanoplastics (MPs/NPs) in plants and the food chain has recently become a top priority. Several research articles highlighted the impact of MPs/NPs on the aquatic food chain; however, very little has been done in the terrestrial ecosystem. A number of studies revealed that MPs/NPs uptake and subsequent translocation in plants alter plant morphological, physiological, biochemical, and genetic properties to varying degrees. However, there is a research gap regarding MPs/NPs entry into plants, associated factors influencing phytotoxicity levels, and potential remediation plans in terms of food safety and security. To address these issues, all sources of MPs/NPs intrusion in agroecosystems should be revised to avoid these hazardous materials with special consideration as preventive measures. Furthermore, this review focuses on the routes of accumulation and transmission of MPs/NPs into plant tissues, related aspects influencing the intensity of plant stress, and potential solutions to improve food quality and quantity. This paper also concludes by providing an outlook approach of applying exogenous melatonin and introducing engineered plants that would enhance stress tolerance against MPs/NPs. In addition, an overview of inoculation of beneficial microorganisms and encapsulated enzymes in soil has been addressed, which would make the degradation of MPs/NPs faster. Graphical Abstract

“…The management of large-sized plastics can produce micro pollution through the accumulation of plastic debris and potentially fragmenting into smaller pieces, classified as particulate plastics, which can be divided into microplastics (fragments < 5 mm) and nanoplastics (fragments < 0.1 µm) [3][4][5][6]. A literature revision allows us to state that the majority of microplastics research reported the presence of plastics or microplastics in aquatic environments, especially the marine ones.…”

Dealing with Plastic Waste from Agriculture Activity

The increase in agricultural production and food quality has forced the growing use of plastics in various activities. The plastic wastes are partially recycled in or outside Portugal; nevertheless, the contaminated wastes are sent to landfill. It is crucial to consider new models for their valorization at a regional level and from a circular economy perspective. In the scope of the Placarvões project, a study was elaborated, which included the types and quantities of plastics used in the irrigation area of the Alqueva Dam, in southern Portugal. The crops that use the most plastic are intensive olive groves, almonds, and table grapes, which represent more than 91% of total plastic waste. The production of activated carbons (ACs) is a solution to avoid plastics landfill. ACs were produced from plastic used on food packaging (PB-Samples) and sheeting film (PS-Samples) by activation with K2CO3. ACs presented well-developed textural properties (PB-K2CO3-1:1–700 and PS-K2CO3-1:1–700 exhibited a volume of 0.32 and 0.25 cm3 g−1 and an apparent surface area of 723 and 623 m2 g−1, respectively). Both ACs performed very well concerning four pesticide removals from the liquid phase. This solution is very promising, such these ACs could be applied in effluent treatments on a large scale.
