Sustainable Plant Production from the Soils Degraded with Microplastics
AI summary Read the abstract
Researchers reviewed how microplastic contamination in agricultural soils disrupts plant growth, alters soil properties, and moves through the soil-plant interface, while exploring remediation strategies for sustainable crop production. Microplastics in farmland soil threaten food security and create a direct pathway for plastic particles to enter the human food supply through crops.
The contamination of soil with microplastics (MPS) has been recognized as the most emerging threat to the soil environment and is a worldwide concern. Yet, the interaction of MPS at soil plant interface, their phytotoxic impacts, and mechanisms associated with their...

Microplastics in Soil-Plant Systems
AI summary Read the abstract
This review synthesized evidence on microplastic contamination in terrestrial soil-plant systems, examining effects on soil structure, nutrient cycling, microbial communities, and plant uptake of plastic particles. Because plants can absorb microplastics and translocate them into edible tissue, agricultural soil contamination represents a direct and underappreciated pathway of human dietary exposure to plastic particles.
Microplastic Pollution in Terrestrial Systems: Sources and Implications for Soil Functioning and Plant Performance
AI summary Read the abstract
Researchers reviewed how microplastics enter terrestrial ecosystems through atmospheric deposition, irrigation, and agricultural mulching and found they reduce soil moisture, disrupt microbial communities, impair nutrient cycling, and harm earthworms — collectively threatening soil health and plant performance in agricultural and natural systems.
Impact of Microplastics on Plant Growth
Microplastics in Agricultural Soils
AI summary Read the abstract
Researchers reviewed what is known about microplastic contamination in agricultural soils, noting that despite hundreds of millions of tonnes of plastic entering the environment annually, very little is understood about how microplastics persist, migrate, and affect soil ecosystems. This knowledge gap is concerning given that contaminated soil directly affects food crops consumed by humans.
Microplastic accumulation in agricultural soils – Impacts on crop microbiomes and soil health
AI summary Read the abstract
Researchers review how microplastics from mulch films, sewage sludge, and wastewater accumulate in agricultural soils, disrupting microbial communities, reducing enzyme activity essential for nutrient cycling, and accumulating in crop tissues, raising food safety concerns and highlighting the need for biodegradable alternatives and better wastewater treatment.
