ClearDiscrepant effects of microplastics on soil phosphorus availability under different phosphorus fertilizer applications
Researchers studied how polyethylene and polylactic acid microplastics interact with different types of phosphorus fertilizers in soil over 56 days. They found that microplastics reduced the amount of plant-available phosphorus in organically fertilized soils by up to 29%, while increasing it in soils treated with mineral fertilizer. The findings suggest that microplastic contamination in farmland could alter how effectively crops access essential nutrients depending on the fertilizer type used.
Impact of Microplastic Contamination on Phosphorus Availability, Alkaline Phosphatase Activity, and Polymer Degradation in Soil
Researchers studied how different types of microplastics at various concentrations affect phosphorus availability and enzyme activity in soil. They found that microplastics altered phosphorus cycling both by directly supplying phosphorus in some cases and by changing microbial enzyme function. The study suggests that microplastic contamination could disrupt soil nutrient dynamics important for maintaining agricultural productivity.

Researchers examined the short-term effects of polyethylene and polypropylene microplastics on soil nutrient cycling, finding that these particles can alter the availability of phosphorus and nitrogen depending on microplastic size and fertilization conditions.
Insight into the transformation of phosphorus in soil affected by microplastics: A review
This meta-analysis found that microplastics significantly decrease phosphorus availability in soil by 7-56%, driven by particle characteristics, soil properties, and exposure duration. Microplastics alter phosphorus cycling through adsorption, changes in soil chemistry, shifts in microbial communities, and modified phosphatase activity, with implications for farmland fertility management.
Effects of micro(nano)plastics on soil nutrient cycling: State of the knowledge.
This review systematically examined how micro- and nano-plastics affect soil nutrient cycling for carbon, nitrogen, and phosphorus, finding that physical interference with soil structure, alteration of microbial communities, and chemical toxicity collectively disrupt mineralization, nitrification, and phosphorus availability in contaminated soils.
Phosphate solubilizing fungi enhance insoluble phosphate dissolution via organic acid production: mechanisms and applications
This review explores how certain fungi can dissolve locked-up phosphorus in soil by producing organic acids, making it available for plants to absorb. While not directly about microplastics, the research is relevant because microplastics in soil can alter microbial communities, potentially disrupting these natural phosphorus-recycling processes. Understanding how soil fungi support plant nutrition helps explain the broader consequences of microplastic contamination on food production.
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.
Effects of different microplastics on the activation of soil potassium by ectomycorrhizal fungi
This study found that both polypropylene (PP) and polylactic acid (PLA) microplastics hindered the growth of an ectomycorrhizal fungus and reduced how much potassium it could release from soil for plants, with PLA being the more harmful of the two. The findings matter because mycorrhizal fungi are critical for forest nutrient cycling, and microplastic contamination of soils could quietly degrade this ecosystem service.
Effects of microplastic types and shapes on the community structure of arbuscular mycorrhizal fungi in different soil types
Researchers examined how different types and shapes of microplastics affect arbuscular mycorrhizal fungi communities across various soil types. The study found that microplastics alter soil structure and chemistry in ways that disrupt these beneficial fungi, which play crucial roles in nutrient exchange, soil stability, and water movement.
Effects of microplastic properties and dissolved organic matter on phosphorus availability in soil and aqueous mediums
Researchers studied how different types of microplastics from agricultural mulching films affect phosphorus availability in soil and water. They found that both conventional plastics like polyethylene and biodegradable plastics like polylactic acid significantly reduced available phosphorus in soil, with smaller and more concentrated particles causing the greatest reductions. The study suggests that microplastic accumulation in agricultural soils may impair nutrient availability for crops.
Effects of microplastics pollution on plant and soil phosphorus: A meta-analysis
Across 781 observations from 73 studies, microplastics significantly reduced plant phosphorus uptake and soil available phosphorus while increasing soil phosphorus leaching. Biodegradable microplastics caused stronger negative effects on soil phosphorus than conventional plastics, and impacts worsened with higher concentrations and longer exposure times.

This study examined how biofilm-covered microplastics of different polymer types affect phosphorus availability in freshwater, finding that polymer type and colonization habitat determined whether plastisphere biofilms acted as phosphorus sources or sinks, with implications for nutrient cycling in aquatic ecosystems.
Microplastics Influence Phosphate Adsorption in Volcanic Ash Soil
Researchers found that adding polyethylene microplastics to volcanic ash soil slightly increased the soil's ability to hold phosphorus but also made phosphorus easier to wash away, potentially reducing its availability to plants. This suggests microplastic contamination in farmland soils could quietly alter nutrient cycling in ways that affect crop growth.

Mycorrhizal-specific responses of rhizosphere soil properties and fine-root traits to polystyrene microplastic addition in a temperate mixed forest
Researchers added polystyrene microplastics to a temperate forest and found they disrupted nutrient cycling differently depending on tree type — increasing nitrogen but decreasing phosphorus near oak-type trees, and doing the opposite near maple-type trees — suggesting microplastic pollution could reshape forest ecosystems over time.

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.
Divergent mechanisms of labile phosphorus accumulation in paddy soils under TPU microplastics versus manure-derived hydrochar: roles of dissolved organic matter and bacterial communities
Scientists found that tiny plastic particles and a charcoal-like material called hydrochar can increase the amount of phosphorus available to rice plants in soil by 14-21%. Both materials work by changing the soil's chemistry and the helpful bacteria that live in it, but they do it in different ways. This matters because phosphorus is essential for growing healthy crops, and understanding how plastic pollution affects soil could help farmers maintain productive rice fields.
