ClearGlobal Meta-Analysis Integrated with Machine Learning Assesses Context-Dependent Microplastic Effects on Soil Microbial Biomass Carbon and Nitrogen
This meta-analysis pooled data from 90 studies to assess how microplastics in soil affect microbial biomass, which is critical for healthy soil function. The research found that in controlled lab settings, microplastics increased microbial biomass carbon by about 10%, but the effect varied greatly depending on plastic type, size, and soil conditions. These soil-level changes matter because altered microbial activity can affect nutrient cycling in agricultural soils that produce the food people eat.
Global Meta-Analysis Integrated with Machine Learning Assesses Context-Dependent Microplastic Effects on Soil Microbial Biomass Carbon and Nitrogen
This global meta-analysis pooled data from 90 studies to examine how microplastics affect soil microbes. In lab settings, microplastics increased microbial biomass by about 10%, with biodegradable plastics having the strongest effects. Temperature was the most important factor influencing these changes. The results suggest microplastics are altering soil ecosystems in ways that could affect agriculture and carbon cycling.
Global meta-analysis reveals differential effects of microplastics on soil ecosystem

This global meta-analysis pooled data from multiple studies and found that microplastic pollution in soil increased CO2 emissions by 25%. Microplastics boost certain soil microbes while reducing overall microbial diversity, changing how carbon cycles through the environment. 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 black soil health: A global meta-analysis
This meta-analysis of 337 cases found that microplastics in black soil increased organic matter, dissolved organic carbon, and available nitrogen but decreased nitrate nitrogen and microbial diversity. Smaller particles, higher concentrations, longer exposure, and conventional (non-biodegradable) plastics caused the most damage, with an overall 12% decrease in black soil health attributed to microplastic contamination.
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.
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.
