The review identifies which biodegradable materials show the most promise for replacing traditional plastic films while maintaining crop benefits.
From plastic mulching to microplastic pollution : An effect assessment of microplastics in the soil-plant system
This review assessed how plastic mulching films contribute to agricultural microplastic pollution, finding that biodegradable alternatives rarely fully degrade under field conditions and instead fragment into microplastics, with both LDPE and biodegradable microplastics producing measurable ecological effects in soil-plant systems.
Effect of Long-Term Biodegradable Film Mulch on Soil Physicochemical and Microbial Properties
Long-term use of biodegradable mulch film was compared to conventional plastic and no-mulch controls in terms of soil physical, chemical, and microbial properties, with results showing that biodegradable mulch altered soil structure and microbial diversity in ways differing from both conventional plastic and bare soil. The findings raise questions about the cumulative effects of biodegradable plastic residues on agricultural soil health.
iMulch: an investigation of the influence of polymers on a terrestrial ecosystem using the example of mulch films used in agriculture
This research project studied how plastic mulch films used in farming break down into microplastics in soil, comparing conventional polyethylene films with biodegradable alternatives. The findings show that both types of mulch release microplastic particles into agricultural soil, though they behave differently in the environment, raising questions about the true sustainability of biodegradable farm plastics.
Biodegradable Mulch for Vegetable Production. A Review
This review examined biodegradable plastic mulches as alternatives to conventional polyethylene mulch films in vegetable production, summarizing yield benefits and degradation performance. Replacing conventional plastic mulch with truly biodegradable alternatives could reduce the large amounts of agricultural microplastics shed by mulch film fragmentation.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
This systematic review examines how plastic mulch films used in agriculture break down over time and release microplastics into farm soil. The films improve crop growth but create lasting environmental damage as plastic fragments accumulate and alter soil properties. The findings underscore the importance of developing truly biodegradable alternatives to protect farmland from microplastic pollution.
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.
The role of biodegradable plastic mulches in soil organic carbon cycling
This review examines the role of biodegradable plastic mulches in soil organic carbon cycling as an alternative to conventional polyethylene mulches, which shed microplastics into agricultural soils. Biodegradable mulches offer potential environmental benefits but their long-term soil impacts are still being studied.
Plastic Mulch‐Derived Microplastics in Agricultural Soil Systems
This review examines how plastic mulch films widely used in agriculture degrade via photodegradation, chemical processes, and microbial activity to form microplastics, and discusses how these microplastics affect soil properties, plant growth, soil microbiomes, and broader agricultural ecosystem health.
Comparing the impact of microplastics derived from a biodegradable and a conventional plastic mulch on plant performance
Researchers directly compared how microplastics from biodegradable and conventional plastic mulch films affect plant growth and found that biodegradable plastic particles actually reduced plant biomass more than conventional plastic particles in some cases. This challenges the assumption that biodegradable plastics are always safer for agriculture, since their breakdown products may still harm crops that end up in the human food supply.
Thickness-dependent release of microplastics and phthalic acid esters from polythene and biodegradable residual films in agricultural soils and its related productivity effects
Researchers conducted a two-year study comparing the release of microplastics and phthalic acid esters from polyethylene and biodegradable mulch films of different thicknesses in agricultural soil. The study found that biodegradable films degraded significantly more than polyethylene films, with thinner films breaking down faster, and that microplastic release from residual films can affect soil properties and crop productivity.
The long-term uncertainty of biodegradable mulch film residues and associated microplastics pollution on plant-soil health
This study investigated the long-term effects of biodegradable mulch film residues and their associated microplastics on soil health and plant growth.
