Degradation and microplastic generation, with associated soil properties and microbial communities, of mulch films exposed above and below ground over 12 months, North Wales, UK
AI summary Read the abstract
Scientists buried and exposed seven types of plastic mulch films (used by farmers to cover soil) for a year in UK fields to see how fast they break down and how many microplastic particles they shed into soil. This matters because as these plastics degrade, they don't just disappear—they fragment into tiny pieces that build up in farmland soil, potentially entering the food we grow and eat, and the study also looked at how this affects soil health and the microbes living there.
This dataset contains measurements from a 12-month field experiment in the UK assessing the degradation, microplastic generation, and environmental impacts of seven plastic mulch films exposed above and below ground, alongside associated soil, environmental, and material property data. Below ground films were either in fine or coarse mesh bags (filled with 20g soil and 5x5 cm plastic piece) to allow only microfauna or micro-, meso-, and macrofauna interaction. The aim of this experiment was to identify the degradation rates of mulch films under UK weather conditions, their microplastic generation rates, and their effect on soil properties and microbial communities (microbial data has been deposited with NCBI: PRJNA1229197). The details can be found in the lineage field and the supporting document.

Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
AI summary Read the abstract
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.
Biodegradable mulch films exhibit slower-than-expected degradation with negligible effects on soil microbial communities
AI summary Read the abstract
Researchers ran a year-long field trial with seven biodegradable plastic mulch films in the UK, finding that none fragmented into soil microplastics as expected and all degraded far more slowly than current industry standards suggest they should. Despite virtually no measurable impact on soil microbial communities, the results challenge the assumption that biodegradable plastics reliably break down under real farming conditions.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
AI summary Read the abstract
This systematic review traces the full lifecycle of plastic mulch films used in farming, from application to breakdown in soil. While these films boost crop yields, they leave behind persistent residues that fragment into microplastics, potentially contaminating soil and groundwater. The review highlights the need for biodegradable alternatives to reduce long-term microplastic accumulation in agricultural land.
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.
Disintegration and mineralization of mulch films and leaf litter in soil
AI summary Read the abstract
This field study tracked the physical disintegration of biodegradable mulch films in agricultural soil over time, monitoring how the films fragment and whether they fully disappear. Understanding the fragmentation and fate of agricultural plastic films in soil is important because these films are a significant source of microplastic contamination of farmland.
