Insight into the transformation of phosphorus in soil affected by microplastics: A review
AI summary Read the abstract
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.
The presence of microplastics (MPs) exerts detrimental effects on soil ecosystems worldwide, subsequently affecting the soil phosphorus (P) cycling. However, the effects of MPs on soil P availability and speciation remain inconsistent, and the underlying factors and mechanisms have not been systematically discussed. Therefore, the impact of MPs on the availability and speciation of P should be clarified for the efficient management of P in the MP-polluted farmland soil. This study provides a systematic review of the effects of MPs on the transformation of P in soil, and special emphasis is given to the influence pathway and mechanisms. In the light of meta-analysis results, the addition of MPs significantly decreased the P availability in soil by 7.28 %-55.94 % (P < 0.05). The responses of soil P species to MPs were mainly driven by MP characteristics, soil properties, and exposure durations. MPs influenced soil P transformation through multiple pathways including P adsorption, alterations in soil physicochemical properties, modifications to microbial communities, and changes in soil phosphatase activities. Further studies should prioritize high-resolution identification of P species and analysis of P-related microbial functional genes to further reveal the evolution of soil P during the MP-mediated process.

Effects of microplastics pollution on plant and soil phosphorus: A meta-analysis
AI summary Read the abstract
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.
Impact of Microplastic Contamination on Phosphorus Availability, Alkaline Phosphatase Activity, and Polymer Degradation in Soil
AI summary Read the abstract
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.
Context-dependent effects of microplastics on soil available phosphorus: An AP-centered multilevel meta-analysis.
AI summary Read the abstract
An analysis combining results from 79 soil studies found that microplastics were linked to an average 12% drop in available phosphorus, a key soil nutrient. The effect varied widely depending on soil acidity, plastic particle size, and plastic type, so the impact was not the same in every situation studied.
Impact of microplastics on soil microbiota and phosphorus dynamics - a review
AI summary Read the abstract
Microplastics from mulching, compost, and sewage sludge accumulate in agricultural soils and disrupt phosphate-solubilizing microbial communities while adsorbing phosphate ions onto polymer surfaces, reducing phosphorus availability and undermining soil fertility. These cascading effects on soil nutrient cycling and microbial ecology represent a serious threat to sustainable agricultural productivity as plastic pollution continues to intensify.
Research on the Effect of Microplastics on Phosphorus in Soil and Water Environment
AI summary Read the abstract
This review synthesizes research on how microplastics interact with phosphorus in soil and water environments, finding that adsorption capacity varies with particle size and polymer type, that aging increases adsorption, and that microplastic-phosphorus complexes alter phosphorus migration and bioavailability in ecosystems.
