Estimation of microplastics entering agricultural soil through the use of biofertilizers
Summary
Scientists found that organic fertilizers made from food waste contain tiny plastic particles called microplastics, which end up in farm soil when the fertilizers are applied. These microscopic plastic bits can potentially enter our food chain through crops grown in that soil. This research helps us understand another way that plastic pollution might affect the food we eat, though more studies are needed to determine the actual health risks.
The use of biofertilizer from anaerobic digestion of organic waste in biogas companies provides a valuable nutrient source for agricultural soils and supports the circular economy. However, their use may also contribute to the input of microplastics (MPs) into soils, and data on this topic remains limited. This study investigated the abundance of MPs (

Quantification and identification of microplastics in organic fertilizers: the implication for the manufacture and safe application
Researchers measured microplastic contamination in 23 commercial organic fertilizers, finding widespread presence at levels that could meaningfully contribute to agricultural soil pollution when fertilizers are applied. The results raise concerns about organic fertilizers as an underappreciated pathway for microplastics entering farm soils and the food system.
Organic fertilizer as a vehicle for the entry of microplastic into the environment
Researchers analyzed organic fertilizers produced from biowaste composting and fermentation and found microplastic particles in all samples tested. The contamination likely enters the fertilizer through improperly sorted household waste that includes plastic packaging and other synthetic materials. The study identifies organic fertilizer application as a previously overlooked pathway for introducing microplastics into agricultural soils, which could have implications for soil health and food safety.
Microplastic contamination of organic fertilisers applied to agricultural soils
This study examined microplastic contamination in organic fertilizers applied to agricultural soils, finding plastic particles in multiple fertilizer types. Organic fertilizers derived from sewage sludge or compost can introduce microplastics into farmland, potentially contaminating crops and groundwater.
Microplastics in the agricultural soils: Pollution behavior and subsequent effects
This review summarizes existing research on how microplastics accumulate in farmland through fertilizers, irrigation, plastic mulch, and atmospheric fallout. Microplastics change soil structure, harm beneficial microbes, and can be taken up by crops, moving through the food chain to humans. The authors emphasize that more research is needed to understand the long-term health risks of eating food grown in microplastic-contaminated soil.
From organic fertilizer to the soils: What happens to the microplastics? A critical review
This review traces how microplastics enter agricultural soil through organic fertilizers made from municipal waste, sewage sludge, and animal manure. During the composting process, the microplastics undergo physical and chemical changes that can make them better at absorbing other pollutants from the soil. The review highlights that applying organic fertilizer to farmland is a major but often overlooked pathway for microplastics to contaminate the food supply.
