This global meta-analysis found that microplastic exposure in soil decreased nitrous oxide emissions by 28.5% and increased methane emissions by 28.6%, though neither change was statistically significant overall. Effects varied dramatically depending on microplastic shape, concentration, soil type, and pH, with fiber-shaped microplastics reducing CO2 emissions by 40% while microplastics in sandy soils increased CO2 by 21%.
Differential impacts of microplastics on carbon and nitrogen cycling in plant-soil systems: A meta-analysis
A meta-analysis of 3,338 observations found that microplastics increased soil CO2 emissions by 25.7% but also boosted soil carbon storage through increases in total carbon (53.3%), soil organic carbon (25.4%), and microbial biomass carbon (19.6%). However, microplastics decreased plant aboveground biomass and reduced nitrate and ammonia volatilization, suggesting that while soil carbon sink capacity may increase, agricultural productivity could suffer.
Effects of microplastic pollution on agricultural soil and crops based on a global meta‐analysis
This meta-analysis examined data from studies worldwide to assess how microplastic pollution affects agricultural soil and crops.

While focused on soil health, this research shows how widespread microplastic pollution is reshaping ecosystems in ways that could ultimately affect climate and agriculture.
Effects of microplastics on soil properties: Current knowledge and future perspectives
This review examines how microplastics affect soil health, including changes to soil structure, chemistry, and the microbial communities that keep soil fertile. The effects vary depending on the type, shape, and amount of plastic present, but in many cases microplastics alter nutrient availability and can even influence greenhouse gas emissions from soil. These changes could threaten crop productivity and food safety, since microplastics are now found in agricultural soils worldwide.
Effects of microplastics on soil C and N cycling with or without interactions with soil amendments or soil fauna
A meta-analysis of soil experiments found that microplastics significantly disrupt carbon and nitrogen cycling — the fundamental processes that keep soils fertile and regulate greenhouse gas emissions — especially when microplastics interact with fertilizers, heavy metals, or soil animals like earthworms. The type of plastic and the presence of other stressors compounded the effects, with some combinations causing substantially greater disruption than either factor alone. This matters because agricultural soils are heavily contaminated with microplastics from mulch films and other sources, threatening both food production and climate regulation.
