Selection of Suitable Organic Amendments to Balance Agricultural Economic Benefits and Carbon Sequestration
Researchers evaluated organic soil amendments for balancing agricultural productivity with soil health, finding that amendment type and application rate affect nutrient cycling, microbial activity, and the potential for microplastic introduction via compost or sludge.
Unraveling the characteristics of microplastics in agricultural soils upon long-term organic fertilizer application: A comprehensive study using diversity indices
Researchers analyzed microplastic contamination in agricultural soils that had received organic fertilizers (pig manure, chicken manure, and sewage sludge compost) for 12 years. All three fertilizer types introduced significant microplastic pollution, with risk levels classified as high across all treatments. This study shows that organic fertilizers, often considered environmentally friendly, are a major pathway for microplastics to enter the soil and potentially the food we grow in it.
Microplastic contamination of organic fertilisers applied to agricultural soils
This study examined microplastic contamination in organic fertilizers applied to agricultural soils, finding plastic particles in multiple fertilizer types. Organic fertilizers derived from sewage sludge or compost can introduce microplastics into farmland, potentially contaminating crops and groundwater.
Quantification and identification of microplastics in organic fertilizers: the implication for the manufacture and safe application
Researchers measured microplastic contamination in 23 commercial organic fertilizers, finding widespread presence at levels that could meaningfully contribute to agricultural soil pollution when fertilizers are applied. The results raise concerns about organic fertilizers as an underappreciated pathway for microplastics entering farm soils and the food system.
Investigating plastic in organic fertilizers: A 2-year comparative study
A two-year field study compared how different types of organic fertilizers affected plastic content in agricultural soils, finding significant variation depending on the feedstock and processing method. The research informs best practices for minimizing plastic inputs to farmland through fertilizer choice.
Research progress on the effects of different fertilizers on soil microorganisms
This review examines how different fertilizer types — chemical, organic, and compound — affect soil microbial communities, summarizing research on how fertilizer-induced changes in microbial diversity and function influence nutrient cycling and crop yield.
Microplastic effects on soil organic matter dynamics and bacterial communities under contrasting soil environments
Researchers compared microplastic effects on soil organic matter dynamics and bacterial communities across contrasting soil environments, finding that the type of microplastic polymer and soil conditions together determine whether microbial activity and carbon cycling are stimulated or suppressed.
Organic fertilizer facilitates the soil microplastic surface degradation and enriches the diversity of bacterial biofilm
Researchers found that organic fertilizer application facilitates surface degradation of microplastics in soil and enriches the diversity of bacterial biofilms on plastic surfaces, suggesting fertilizer use influences microplastic behavior and fate in agricultural soils.
Microplastics identification and quantification in the composted Organic Fraction of Municipal Solid Waste
Researchers quantified microplastics in composted organic municipal solid waste from five facilities, finding contamination levels that raise concerns about compost quality and the potential transfer of microplastics to agricultural soils through organic waste recycling.
Living in the plastic age - Different short-term microbial response to microplastics addition to arable soils with contrasting soil organic matter content and farm management legacy
Adding polyethylene or polypropylene microplastics to two agricultural soils did not severely disrupt overall microbial activity or nitrogen cycling, but polypropylene reduced microbial biomass, especially in the organically managed soil. The results suggest that soil management history influences how resilient soil microbiomes are to microplastic contamination.
Fertilization and Soil Microbial Community: A Review
This review examines how different types of chemical and organic fertilizers affect soil microbial community composition and function. Researchers found that organic fertilizers generally promote greater microbial diversity and activity compared to chemical fertilizers alone. While focused broadly on soil health, the findings are relevant to understanding how agricultural practices may influence the microbial degradation of environmental contaminants including microplastics.
Optimizing Microbial Composition in Soil Macroaggregates Enhances Nitrogen Supply Through Long-Term Straw Return
Despite its title referencing soil nitrogen and straw return, this paper studies how long-term agricultural straw incorporation affects microbial communities and nitrogen cycling within soil aggregates — not microplastic pollution. It examines bacterial and fungal biodiversity changes in soil over 13 years and is not relevant to microplastics or human health.
Long-term application of organic compost is the primary contributor to microplastic pollution of soils in a wheat–maize rotation
Researchers found that 11 years of organic compost application was the primary contributor to microplastic accumulation in wheat-maize rotation soils, with pig and cow manure composts introducing significant quantities of microplastic particles into agricultural fields.
[Effect of Low-density Polyethylene Microplastics on Soybean-soil-microbial System].
A pot experiment explored how different concentrations of low-density polyethylene microplastics affect soybean plants, the soil they grow in, and the microbial communities in that soil. Higher microplastic concentrations inhibited soybean growth, reduced soil enzyme activity, and altered microbial diversity in ways that could impair soil fertility. As microplastic contamination of agricultural soils continues to grow, these findings suggest real risks to food crop productivity and soil ecosystem health.
Effects of Two Different Proportions of Microbial Formulations on Microbial Communities in Kitchen Waste Composting
Not relevant to microplastics — this composting study evaluates how different microbial inoculant formulations affect the maturity, odor emissions, and microbial communities during kitchen waste composting.
Unveiling the abundance and potential impacts of microplastic contamination in commercial organic fertilizers/compost produced from different solid waste
Researchers analyzed commercial organic fertilizers made from different waste sources and found microplastics in 80% of the samples, with compost from mixed municipal waste containing the highest levels. The estimated amounts of microplastics being introduced into agricultural soils through these fertilizers exceeded previous reports. The study highlights the need for stricter regulations on organic fertilizer quality to prevent microplastic contamination of farmland.
Parameters of labile organic carbon as the indicators of the stability of soil organic matter under different land use
Despite its title referencing soil organic carbon and land use, this paper studies chemical indicators of soil organic matter stability under different farming practices — not microplastic pollution. It examines which carbon fractions best signal how organic matter is protected in forest and agricultural soils, and is not relevant to microplastics or human health.

Microplastic pollution and the related ecological risks of organic composts from different raw materials
Researchers analyzed microplastic contamination in 124 organic compost samples made from livestock manure, poultry waste, crop straw, and solid waste, finding that all types contained significant microplastic loads. Solid waste compost had the highest levels while crop straw compost had the lowest, and the particles showed signs of weathering and mineral attachment. The findings suggest that applying organic compost to farmland may be an underappreciated source of microplastic pollution entering agricultural soils.
