ClearInfluence 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.
Biochar and Microplastics Affect Microbial Necromass Accumulation and CO2 and N2O Emissions from Soil
Researchers investigated how biochar and polyethylene microplastics interact in soil and found that both reduced CO2 and N2O greenhouse gas emissions, though through different mechanisms. Microplastics decreased emissions primarily by reducing dissolved organic matter and bacterial biomass, while biochar suppressed nitrogen-cycling genes. When combined, microplastics in biochar-treated soil unexpectedly increased microbial necromass carbon by disrupting soil aggregates, revealing complex interactions between these two soil amendments.

Rice yield and carbon dioxide emissions in a paddy soil: A comparison of biochar and polystyrene microplastics
Researchers compared the effects of biochar and polystyrene microplastics on rice growth and carbon dioxide emissions in paddy soil. Both materials increased CO2 emissions, but biochar improved rice yield while microplastics did not provide the same benefits. The study suggests that microplastic accumulation in rice paddies could worsen greenhouse gas emissions without the soil-improvement benefits that biochar offers.

Researchers examined how biochar interacts with conventional and biodegradable microplastics in soil to affect coriander growth, nitrous oxide emissions, and microbial communities. They found that biochar generally reduced soil nitrous oxide emissions, but this benefit was diminished or even reversed when certain microplastics were present. The study suggests that the combined use of biochar and plastic mulch in agricultural fields can produce unexpected effects on greenhouse gas emissions and soil microbiology.

Comparative evaluation of the impacts of different microplastics on greenhouse gas emissions, microbial community structure, and ecosystem multifunctionality in paddy soil
Researchers compared the effects of polylactic acid, low-density polyethylene, and polypropylene microplastics on greenhouse gas emissions and soil ecosystem functions in paddy soil over 41 days. They found that all three microplastic types increased soil carbon nutrients and pH, while suppressing CO2 and N2O emissions in most cases, leading to reduced global warming potential. The study suggests that different microplastic polymers have varying effects on soil ecosystem multifunctionality, with some types improving it and others having detrimental effects.

Researchers found that biodegradable plastic (PLA) microplastics in mangrove soil increased the release of greenhouse gases, especially carbon dioxide and methane, from deeper soil layers. The microplastics altered soil bacterial communities in ways that boosted methane-producing organisms. This finding is important because biodegradable plastics are often marketed as environmentally friendly, but they may still harm ecosystems by accelerating carbon release from soils.
