ClearMicroplastics induced the differential responses of microbial-driven soil carbon and nitrogen cycles under warming
Researchers examined how the combination of microplastic pollution and warming temperatures affects soil carbon and nitrogen cycling driven by microbial communities. The study found that microplastics altered microbial responses to warming in ways that disrupted both carbon decomposition and nitrogen transformation processes in soil.
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.

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.
Microplastics in heavy metal-contaminated soil drives bacterial community and metabolic changes
Researchers found that adding common microplastics to soil already contaminated with heavy metals significantly changed the bacterial communities and their metabolic processes. The microplastics increased competition among bacteria and shifted how they process energy, while Proteobacteria became more abundant as a stress response. This matters because when microplastics and heavy metals combine in agricultural soil, they may disrupt the microbial ecosystems that keep soil healthy for growing food.
Microbes drive metabolism, community diversity, and interactions in response to microplastic-induced nutrient imbalance
Researchers investigated how conventional and biodegradable microplastics alter soil nutrient balances and the resulting effects on microbial metabolism, community diversity, and species interactions. The study found that microplastic-induced nutrient imbalances significantly influenced soil microbial processes, with different types of microplastics producing distinct effects on carbon and nitrogen cycling.
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.
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.
Influence of polyethylene terephthalate microplastic and biochar co-existence on paddy soil bacterial community structure and greenhouse gas emission
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. The study suggests that biochar may help mitigate some of the negative soil health effects of microplastic contamination in paddy fields.
Impact of microplastics on the in situ, high-resolution of key nutrient dynamics at the soil-water interface in rice fields
Researchers used a high-resolution in-situ technique (diffusive gradients in thin films) to measure how microplastics alter the cycling of nitrogen and phosphorus at the soil-water interface in rice paddies. They found that microplastics disrupted the normal distribution and exchange of these key nutrients, with significant variation depending on whether nitrogen or phosphorus was measured. Since rice is a global staple crop, disruption of nutrient dynamics in paddy soils by microplastic contamination has direct implications for food security.

Microplastics added to rice paddy soil unexpectedly reduced ammonia volatilization compared to unamended controls, with combined addition of microplastics and hydrochar further altering ammonia loss patterns, and microplastics changing soil bacterial community structure in ways that may affect nitrogen cycling in irrigated agricultural ecosystems.
Interactive effects of drought and microplastic particle size on soil bacterial community structure
Scientists found that tiny plastic particles in soil become more harmful to the beneficial bacteria that keep soil healthy when combined with drought conditions. The smallest plastic particles caused the most damage, reducing the diversity of helpful soil bacteria by up to 29% during dry conditions. This matters because healthy soil bacteria are essential for growing nutritious food, and climate change is making both plastic pollution and droughts more common worldwide.
Effect of Temperature on Microplastic Degradation in Soil Environment
Researchers investigated how temperature affects the degradation of microplastics in soil, testing samples at different temperature conditions over time. They found that higher temperatures accelerated the physical breakdown of plastic particles in the soil environment. The study suggests that climate and seasonal temperature variations may play a role in determining how quickly microplastics fragment into even smaller particles in agricultural and natural soils.
Concurrence of microplastics and heat waves reduces rice yields and disturbs the agroecosystem nitrogen cycle
Researchers found that while microplastics or heat waves alone had mild effects on rice crops, the combination reduced yields by about 32% and significantly lowered grain protein and nutrient content. The dual stress disrupted nitrogen cycling in the soil and shifted nutrient distribution within the plants, reducing photosynthesis. This matters because climate change and plastic pollution are increasing simultaneously in agricultural regions.

Researchers found that polyethylene and PVC microplastics in soil increased nitrification (a key step in the nitrogen cycle) and changed the composition of nitrogen-processing bacteria. These changes could affect soil fertility and the availability of nutrients for crops. The study highlights how microplastic contamination in agricultural soil may have hidden effects on food production by altering fundamental soil processes.
Microplastics affect C, N, and P cycling in natural environments: Highlighting the driver of soil hydraulic properties
This study found that common microplastics like polyethylene and polypropylene significantly change how soil handles water and nutrients by increasing water content, reducing soil density, and altering bacterial communities involved in nitrogen and carbon cycling. These changes affected how nutrients are stored in soil, with increases of 12 to 93 percent in nitrogen and carbon storage depending on the plastic type and amount. The findings suggest microplastic pollution could disrupt the fundamental soil processes that support food production.
