[Effects of Microplastic Input on N2O Production and Pathways in Rice-wheat Rotational Cropland Soils in Subtropical Hilly Areas].
AI summary Read the abstract
I need more of the abstract text to write an accurate summary, since only a fragment ("O productions from the soil") was provided. Based on the title alone, here's a cautious summary: Researchers studied how microplastics (tiny plastic bits from broken-down waste) in farm soil affect the release of nitrous oxide, a powerful greenhouse gas, in fields where rice and wheat are grown in rotation. This matters because microplastic pollution is widespread in farmland, and understanding its effects on soil chemistry could reveal hidden environmental costs of plastic waste—though this study focuses on climate impact rather than dire

Researchers conducted a controlled laboratory incubation experiment to examine the effects of polyethylene and polybutylene adipate co-terephthalate microplastics on N2O emissions and nitrogen transformations in tropical agricultural soils from a pepper-corn cropping system in Hainan Province, China.
Microplastics in agricultural soil: Unveiling their role in shaping soil properties and driving greenhouse gas emissions
AI summary Read the abstract
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.

AI summary Read the abstract
This review synthesizes current research on how microplastics affect soil nitrogen cycling, including N2O emissions, nitrogen transformation processes, functional enzyme activity, and nitrogen-related genes, highlighting inconsistent findings due to variability in microplastic properties, experimental conditions, and spatial-temporal scales.
The effect of microplastic pollution on rice growth, paddy soil properties, and greenhouse gas emissions: A global meta-analysis
AI summary Read the abstract
This global meta-analysis of 40 studies found that microplastics reduce rice biomass by inducing oxidative stress and inhibiting photosynthesis, while depleting soil nitrogen, phosphorus, and organic carbon. Microplastics also stimulate nitrous oxide emissions from paddy soils, posing a dual threat to food security and climate through impaired rice production and increased greenhouse gas output.
Effect of microplastics on carbon, nitrogen and phosphorus cycle in farmland soil: A meta-analysis
AI summary Read the abstract
This meta-analysis of 102 studies found that microplastics in farmland soil increased soil organic carbon, microbial biomass carbon, and microbial biomass nitrogen, but also elevated CO2, methane, and nitrous oxide emissions through enhanced carbon mineralization and denitrification. Microplastic biodegradability, size, concentration, and soil properties all drove these effects, suggesting agricultural microplastic pollution may worsen greenhouse gas emissions from farmland.
