Biochar enhances microbial nitrogen retention in polylactic acid-contaminated soil under freeze-thaw cycles

AI summary Read the abstract

Researchers simulated repeated freeze-thaw cycles on soil amended with polylactic acid microplastics and biochar, finding that biochar mitigated PLA-driven disruptions to nitrogen cycling by raising soil pH, suppressing denitrification genes, upregulating nitrogen assimilation pathways, and reshaping the microbial community toward nitrogen-retaining taxa — with implications for managing biodegradable plastic residues in cold-region farmland.

Differential effects of microplastics on soil organic carbon via lignin phenols and amino sugars in soil aggregates

AI summary Read the abstract

Pot experiments with corn showed that both conventional polyethylene and biodegradable PLA microplastics reduced the accumulation of microbial carbon in soil aggregates, disrupting how organic matter builds up in the ground. Because microplastic-derived carbon can be miscounted as soil organic carbon, these findings suggest we may be overestimating soil health in contaminated agricultural fields.

Soil Aggregates and Organic Carbon Transformation in Response to Microplastics Pollution

AI summary Read the abstract

Researchers synthesized 131 studies on microplastics in agricultural soils and found that microplastics destabilize soil aggregates, accelerate organic carbon mineralization, and stimulate microbial activity in ways that collectively degrade soil structure and increase carbon loss to the atmosphere.

Impacts of microplastics on terrestrial soil carbon dynamics

AI summary Read the abstract

This synthesis shows that microplastics disrupt soil organic carbon sequestration through multiple mechanisms, including leaching dissolved organic matter, altering microbial carbon pump efficiency, and creating hotspots that modify mineral-organic matter interactions within soil aggregates. As microplastics accumulate in agricultural soils globally, their interference with carbon storage could undermine both climate mitigation efforts and the soil ecosystem services that support food production.

Plant presence fundamentally alters soil microbial and biogeochemical responses to polylactic acid microplastics: Evidence from unplanted vs. maize-planted microcosms

AI summary

This study investigated microplastic transport and redistribution in deep-sea sediment systems, examining how particle characteristics and ocean current dynamics influence deposition patterns. The findings reveal that deep-sea environments accumulate microplastics from distant surface sources, with long-term implications for benthic ecosystem health.
