ClearMicroplastic effects on carbon cycling processes in soils
Researchers reviewed how microplastics affect carbon cycling processes in soils, including their influence on microbial activity, plant growth, and litter decomposition. Since microplastics are themselves carbon-based materials, they can directly alter soil carbon stocks while also indirectly shifting microbial communities. The study calls for a major research effort to understand the widespread effects of microplastics on soil functioning and terrestrial ecosystem health.
Microplastics alter soil carbon cycling: Effects on carbon storage, CO 2 and CH 4 emission and microbial community
This systematic review examines how microplastics in soil affect carbon cycling, including greenhouse gas emissions and carbon storage. The effects depend heavily on plastic type and size, with biodegradable plastics generally having a bigger impact. Understanding these soil-level changes matters because disrupted carbon cycles can worsen climate change, which in turn affects the food and water systems we all depend on.

This review of 46 studies examines how microplastics influence carbon cycling in different soil ecosystems.

The results suggest microplastic accumulation in farmland could impair soil carbon storage.
The impacts of microplastics on the cycling of carbon and nitrogen in terrestrial soil ecosystems: Progress and prospects
This review examines how microplastics in soil affect the cycling of carbon and nitrogen, two elements essential for plant growth and soil health. Microplastics alter soil microbial communities and enzyme activity in ways that change greenhouse gas emissions and nutrient availability, which could ultimately affect crop production and the food supply.
Disentangling microplastics effects on soil structure, microbial activity and greenhouse gas emissions
Researchers studied how microplastics affect soil structure, microbial activity, and greenhouse gas emissions, finding complex interactions that depend on microplastic type and concentration. The presence of microplastics in soils can alter the biological processes that regulate carbon storage and nutrient cycling.
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.

This review explores how microplastics in soil disrupt the carbon cycle by masquerading as natural soil carbon, changing how organic matter breaks down, and altering the communities of microbes that keep soil healthy.
