Researchers conducted a six-month experiment to understand how polyethylene microplastics in soil affect nitrogen cycling, a process critical for soil fertility and plant nutrition. They found that while total nitrogen levels stayed stable, microplastics significantly altered the forms of nitrogen present by increasing ammonium and nitrate while decreasing dissolved organic nitrogen. The study suggests that microplastics reshape soil microbial communities and their nitrogen-processing activities, potentially disrupting the natural nutrient balance in agricultural soils.

The study highlights how microplastic contamination in agricultural soil may have hidden effects on food production by altering fundamental soil processes.
Interactive Effects of Microplastic Pollution and Global Warming on Soil Carbon and Nitrogen Dynamics in Subtropical Forests
Scientists studied how tiny plastic particles (microplastics) affect forest soil when combined with warming temperatures, and found that these plastics disrupt how soil processes carbon and nitrogen - key nutrients that keep ecosystems healthy. The plastic pollution made soils more sensitive to temperature changes and altered important chemical cycles that plants depend on for growth. This matters because microplastics are everywhere in our environment, and this research shows they could harm the forest ecosystems that clean our air and water, especially as the planet continues to warm.

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.
Microplastic 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.

Two particle sizes of microplastics were added to fertilized soil and their effects on dissolved organic carbon, greenhouse gas fluxes, and microbial communities were measured, finding reduced global warming potential due to decreased methane emissions but changes in bacterial and fungal community composition. The study reveals complex interactions between microplastics and soil carbon cycling processes.
Effects of microplastics on soil microorganisms and microbial functions in nutrients and carbon cycling – A review
This review examines how microplastics in soil alter the communities of bacteria and fungi that are essential for recycling nutrients like nitrogen, phosphorus, and carbon. Microplastics can increase certain beneficial bacteria but decrease others that are important for soil fertility, and they also carry toxic chemicals that further disrupt microbial life. The authors note that most studies are short-term lab experiments, and long-term field studies are needed to understand real-world impacts.
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.
