ClearBacterial-charged biochar enhances plant growth and mitigates microplastic toxicity by altering microbial communities and soil metabolism
Researchers tested whether adding bacteria and biochar (a charcoal-like material) to microplastic-contaminated paddy soil could help rice plants recover, finding that the combined treatment increased shoot weight by over 100% and dramatically improved nutrient uptake genes. The treatment also enriched beneficial soil microbes and reduced oxidative stress in rice, offering a promising strategy for restoring agricultural soils polluted with microplastics.
Investigation of the effects of polyethylene microplastics at environmentally relevant concentrations on the plant-soil-microbiota system: A two-year field trial
Researchers conducted a two-year field trial to study how polyethylene microplastics at environmentally relevant concentrations affect crops, soil, and microbial communities in a rice-wheat rotation system. They found that microplastics did not harm wheat growth but actually increased rice grain weight and plant height, while reducing soil nutrient levels including nitrogen and phosphorus. The study reveals that microplastics can alter soil bacterial communities and disrupt metabolic processes in ways that differ between crop seasons.
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.

Researchers studied how microplastic contamination in rice paddy soil interacts with high temperatures to alter nutrient cycling and soil bacteria. They found that at normal temperatures microplastics reduced key soil nutrients, but at elevated temperatures the effect reversed, actually increasing nutrient availability and microbial diversity. The findings suggest that climate change could amplify the ways microplastics disrupt agricultural soil ecosystems.

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.

Researchers studied how different types of microplastics at various concentrations affect phosphorus availability and enzyme activity in soil.

The study suggests that microplastic contamination could disrupt soil nutrient dynamics important for maintaining agricultural productivity.

Researchers tested a novel microbial consortium containing bacterial and fungal strains to mitigate the harmful effects of polyethylene microplastics on soil and sunflower growth. The study found that microplastics altered soil pH, electrical conductivity, and organic carbon levels, but the microbial consortium treatment helped counteract some of these detrimental effects on the soil-plant system.

Researchers studied how polyethylene terephthalate microplastics and biochar, both common in agricultural soils, affect soil bacteria and greenhouse gas emissions during rice cultivation. They found that microplastics alone reduced bacterial diversity, but adding biochar alongside the microplastics partially restored microbial communities and altered gas emissions.

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.

Researchers examined how polyethylene microplastics and nitrogen fertilizer individually and together affect soil microorganisms and rapeseed crop growth. They found that while microplastics alone reduced protist diversity and altered soil communities, adding nitrogen fertilizer counteracted many of these negative effects. The study suggests that nitrogen fertilization may be a practical strategy to buffer agricultural soils against some of the harmful impacts of microplastic contamination.

The review proposes that ecological engineering strategies like microbial bioremediation and organic soil amendments could help protect agricultural land from plastic contamination.
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.
