[Effects of Polyethylene Microplastics on the Growth and Quality of Brassica campestris L. in a Three-season Consecutive Cultivation].
Researchers investigated how polystyrene microplastics of four particle size fractions (under 25, 25-48, 48-150, and 150-850 micrometers) affect the growth, development, and nutrient quality of Chinese cabbage (Brassica campestris L.) across three consecutive cultivation seasons in pot experiments, finding significant size-dependent inhibitory effects on plant growth and soil nutrient supply.
Macro- and micro-plastic accumulation in soils under different intensive farming systems: A case study in Quzhou county, the North China Plain
Soil samples from six farming systems in the North China Plain showed macroplastic abundances from 0.2 to 46.8 kg/ha and microplastic concentrations up to 3.7×10⁴ items/kg, with greenhouse and mulched vegetable fields showing the highest contamination.
On the quest for novel bio-degradable plastics for agricultural field mulching
This review examined the challenge of developing biodegradable plastic mulch materials suitable for agricultural use, noting that plasticulture consumes about 6.7 million tons of plastic annually, most of which cannot be practically recycled. The authors assessed candidate biodegradable polymers based on their degradation rates in soil, mechanical performance, and cost.
A Biodegradable Pot Technique, and Emergy Analysis to Improve Restoration Outcomes of Potamogeton Perfoliatus L.
This study developed a biodegradable planting pot technique for restoring native aquatic vegetation in the Chesapeake Bay, finding it improved seedling survival over conventional methods. The approach aims to restore declining seagrass beds while avoiding introduction of new plastic materials into sensitive estuarine habitats.
Programmed biodegradation of polymer blends and composites for applications in agriculture and horticulture
Researchers developed and evaluated polymer blends and composites based on PHBV, PHBH, PBS, and PLA for agricultural and horticultural applications, demonstrating through greenhouse cultivation trials that these materials retained full mechanical integrity during use and achieved programmed biodegradation after harvest, reducing the risk of persistent microplastic accumulation compared to conventional plastics.
Development of a method for determining microplastic content in agricultural soils with research on minimization measures
Researchers developed a methodology for measuring microplastic content in agricultural soils, identifying sprayer tank design, tank materials, and operational parameters as key contamination factors, and proposed practical minimization measures including tank volume optimization.
Plastic mulching in agriculture. Trading short-term agronomic benefits for long-term soil degradation?
This study examined plastic mulch use in agriculture, arguing that short-term crop benefits come with long-term costs as mulch fragments accumulate in soil as microplastics and disrupt soil structure, biology, and water dynamics.
Plant-driven strategies for mitigating microplastic pollution in agricultural ecosystems
Researchers review how microplastics damage agricultural soils and crops — disrupting soil structure, starving plants of nutrients, and triggering oxidative stress — and explore plant- and microbe-based strategies like root-associated bacteria and biochar amendments as promising but underexplored tools for cleaning up plastic-contaminated farmland.
Novel insights related to soil microplastic abundance and vegetable microplastic contamination
Researchers analyzed microplastic contamination in farmland soils and the vegetables grown in them, finding that polyethylene and polypropylene were the most common plastic types in soil. Chinese cabbage had the highest vegetable contamination levels, and there was a moderate correlation between soil and vegetable microplastic concentrations. The study provides real-world evidence that microplastics in agricultural soil can transfer into the food crops people eat.

Microplastics interaction with terrestrial plants and their impacts on agriculture
This review summarizes what is known about how microplastics interact with terrestrial plants, including how they are taken up, transported through plant tissues, and affect growth and agricultural productivity. Researchers note that while marine microplastic research is extensive, studies on soil ecosystems and crop impacts remain limited. The study highlights the need for more research on how microplastics in agricultural soils may ultimately affect food safety and human health.
Is mulch film itself the primary source of meso- and microplastics in the mulching cultivated soil? A preliminary field study with econometric methods
A field study examined whether mulch films were the primary source of meso- and microplastics in mulched agricultural soils using econometric methods to compare plastic-mulched and non-mulched fields, finding that while mulch contributed to soil plastic loads, it was not the sole source. The study challenges the assumption that plastic mulch is always the dominant microplastic source in farmed soils.
Effects of Organic Fertilizer on Photosynthesis, Yield, and Quality of Pakchoi under Different Irrigation Conditions
This paper is not about microplastics. It studies how organic fertilizer affects the photosynthesis, yield, and quality of pakchoi (a type of Chinese cabbage) under different irrigation conditions. The research focuses entirely on agricultural fertilizer management and crop science with no connection to microplastic contamination or health effects.
Employing a systems approach to unravelling the complexities of the agricultural plastics value chain
Researchers used a systems analysis approach to map the full lifecycle of plastics used in agriculture — from production to disposal — and found that while these materials boost crop yields, they create serious sustainability problems including microplastic accumulation in soil and chemical leaching. The study identifies critical gaps in data, policy, and infrastructure needed to manage agricultural plastic waste and transition toward more sustainable alternatives.
Microplastic effects on plants
This perspective paper proposed mechanistic pathways through which microplastics could affect plant growth positively or negatively, including effects on soil structure, water availability, nutrient cycling, and root-microbe interactions. The authors argue that plant species and plastic type will determine the direction of effects, and call for dedicated research to fill a major gap in terrestrial microplastic science.
Mechanisms of microplastic accumulation in the root zones of agricultural soils
Scientists found that tiny plastic pieces from farm materials like mulch films get stuck in soil and don't wash away easily, causing them to build up over time in areas where food is grown. This matters because these microplastics can potentially enter our food supply through crops that absorb them from contaminated soil. The research shows it's very difficult to remove these plastic particles once they're in farmland, suggesting we need better prevention methods to protect our food system.
