ClearBiochar-mediated remediation of low-density polyethylene microplastic-polluted soil-plant systems: Role of phosphorus and protist community responses
Researchers found that adding biochar (a charcoal-like soil additive) to soil contaminated with microplastics helped improve plant growth by restoring phosphorus cycling. The microplastics disrupted soil microbe communities, but biochar treatment shifted these communities in beneficial ways. This suggests biochar could be a practical tool for farming in soils contaminated with plastic pollution.
Exploring the potential of biochar for the remediation of microbial communities and element cycling in microplastic-contaminated soil
Scientists found that adding biochar (a charcoal-like material made from plant waste) to soil contaminated with microplastics helped restore healthy microbial communities and nutrient cycling. The biochar reversed negative effects that microplastics had on soil chemistry, including nitrogen and phosphorus availability. This suggests biochar could be a practical tool for repairing farmland damaged by microplastic pollution.
Combined effect of biochar and soil moisture on soil chemical properties and microbial community composition in microplastic‐contaminated agricultural soil
Biochar was applied to microplastic-contaminated agricultural soil under different moisture conditions, with results showing that biochar improved soil chemical properties and shifted microbial communities in ways that partially offset microplastic-induced degradation. The study suggests biochar as a practical soil amendment to mitigate microplastic impacts in farming systems.
Impact of Coexistence of Microplastics and Biochar on the Abundance and Structure of Soil Fungal Communities
Researchers investigated the effects of polypropylene, polyethylene, and PVC microplastics — alone and in combination with biochar — on soil fungal community structure, diversity, and functional prediction in agricultural soil. Microplastics increased overall fungal abundance but reduced diversity indices, with dominant taxa including Ascomycota, Basidiomycota, Mortierella, Aspergillus, and Fusarium, and coexistence with biochar amplifying these effects beyond microplastics alone.

Researchers examined how different microplastic types affect soil inorganic phosphorus mobilization, finding that polymer type and particle size influence phosphorus release from soil minerals, with implications for nutrient cycling in plastic-contaminated soils.
Phosphorus fertiliser application mitigates the negative effects of microplastic on soil microbes and rice growth
Researchers found that adding phosphorus fertilizer to soil contaminated with microplastics helped counteract the negative effects of the plastics on rice growth and soil microbial communities. The microplastics alone disrupted bacterial interactions and suppressed plant development, but fertilizer application restored much of the lost productivity. The study offers practical guidance for managing agricultural soils in areas affected by microplastic pollution.
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.
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.
Biochar Mitigates the Negative Effects of Microplastics on Sugarcane Growth by Altering Soil Nutrients and Microbial Community Structure and Function
Microplastic contamination in sugarcane-growing soils in China reduces crop biomass and degrades soil nutrients and microbial diversity. Adding biochar to microplastic-polluted soil helped offset these harms — restoring sugarcane growth, stabilizing soil pH, and improving bacterial community richness. The findings suggest biochar is a practical tool for rehabilitating agricultural land affected by plastic pollution.

A long-term field study found that adding biochar (a charcoal-like material) and organic fertilizer to farm soil significantly boosted beneficial soil microbes involved in nutrient cycling and improved overall ecosystem health by up to 30%. While not directly about microplastics, biochar has been shown in other studies to bind microplastics and reduce their movement through soil, making this approach potentially beneficial for both soil productivity and microplastic mitigation on farms.

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.
Plant-driven strategies for mitigating microplastic pollution in agricultural ecosystems
Researchers review how microplastics damage agricultural soils and crops — disrupting soil structure, starving plants of nutrients, and triggering oxidative stress — and explore plant- and microbe-based strategies like root-associated bacteria and biochar amendments as promising but underexplored tools for cleaning up plastic-contaminated farmland.
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.
