ClearMicroplastics in agricultural soil: Unveiling their role in shaping soil properties and driving greenhouse gas emissions
This review examines how microplastics in agricultural soils affect carbon and nitrogen cycles and alter greenhouse gas emissions. Researchers found that microplastics reduce soil water retention, decrease soil respiration, and increase emissions of carbon monoxide, methane, and nitrous oxide. The study reveals that microplastic contamination in farmland may have broader climate implications by disrupting the soil processes that regulate greenhouse gas fluxes.
Microplastics and Soil Greenhouse Gas Emissions: A Critical Reflection on Meta-Analyses
This meta-analysis pools data from multiple studies to assess whether microplastics in agricultural soil affect greenhouse gas emissions.

Plastic Pollution in Agriculture as a Threat to Food Security, the Ecosystem, and the Environment: An Overview
This review examines how plastic products used in agriculture -- from mulch films to greenhouse covers -- contribute to microplastic pollution in soil, water, and crops. While plastics help boost crop production and food quality, their breakdown releases microplastics that can be taken up by plants and enter the food chain. The paper discusses strategies to reduce plastic pollution in farming, which is important because agricultural microplastics represent a direct pathway to human dietary exposure.
Impact of plastic mulching as a major source of microplastics in agroecosystems
This review examines how plastic mulch films used in agriculture break down into microplastics over time, making farmland a major source of soil microplastic pollution. The accumulated microplastics can alter soil properties, affect plant growth, and be taken up by crops that humans eat. The study highlights the need for better end-of-life management of agricultural plastics and more research on how farm-sourced microplastics enter the food chain.

The Impact of Resource Spatial Mismatch on the Configuration Analysis of Agricultural Green Total Factor Productivity
This study analyzed how the spatial distribution of agricultural resources affects green farming productivity in China from 2005 to 2021. While not directly about microplastics, it found that pollutant emissions from fertilizers and petroleum products significantly hinder sustainable agriculture. The findings are indirectly relevant because agricultural plastic waste, including mulch films, is a major source of microplastic contamination in farmland soil.

Microplastics andSoil Greenhouse Gas Emissions: ACritical Reflection on Meta-Analyses
This meta-analysis found that different types of microplastics in agricultural soil affect greenhouse gas emissions in varying ways, with some plastics increasing methane and carbon dioxide output. While focused on environmental impact rather than direct health effects, the findings highlight how microplastic contamination of farmland can have far-reaching consequences for both climate and food production.
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.
Agricultural plastics and environmental sustainability: Assessment and remediation strategies
This review examines the environmental and socioeconomic impacts of agricultural plastics including mulch films, irrigation pipes, and greenhouse covers, and evaluates management strategies such as recycling, composting, biodegradable alternatives, and circular economy models for reducing microplastic accumulation.
Microplastics andSoil Greenhouse Gas Emissions: ACritical Reflection on Meta-Analyses
This meta-analysis examines whether microplastics in agricultural soil affect greenhouse gas emissions. While focused on environmental impact rather than direct human health, it matters because microplastics in farm soil can enter the food supply and contribute to broader climate and health concerns.
Role of soil microplastic pollution in climate change
This review examined the bidirectional relationship between soil microplastic pollution and climate change, exploring how microplastics affect soil carbon cycling, greenhouse gas emissions, and how climate factors influence microplastic behavior in soils.
Environmental fate and effects of mulch films on agricultural soil: A systematic review from application to residual impact
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.
Effects of microplastics on microbial community and greenhouse gas emission in soil: A critical review
This review examines how microplastics in soil affect microbial communities and greenhouse gas emissions, finding that microplastics can alter the abundance and activity of soil bacteria in ways that increase carbon dioxide and nitrous oxide release. The plastics change soil structure and chemistry, creating conditions that favor certain gas-producing microbes over others. These effects could worsen climate change while also disrupting soil fertility, with indirect consequences for food production.
