Microplastics in Soil

Explore the latest research, scientific studies, environmental assessments, and agricultural developments related to Microplastics in Soil. Stay informed on soil health, plastic pollution, crop growth, soil microorganisms, agricultural plastics, food safety, and sustainable farming.

Microplastics in soil are increasingly recognized as an emerging environmental issue in agricultural systems. They can enter farmland through plastic mulch films, irrigation water, wastewater, sewage sludge, organic fertilizers, agricultural films, and other sources. Recent research indicates that microplastics can influence soil structure, water movement, nutrient cycling, microbial communities, and plant growth, although the magnitude and direction of these effects can vary considerably with polymer type, particle size, concentration, soil characteristics, and crop species.

Agricultural soils are an important area of research because microplastics can persist and accumulate in the soil environment and potentially interact with pesticides, heavy metals, pathogens, and other contaminants. A 2026 review highlighted potential effects on soil porosity, aggregation, nutrient availability, and microbial processes, while a recent multi-country study found that soil properties and climate were important drivers of microplastic enrichment patterns in agricultural soils.

Research is also examining whether microplastics can be taken up by crops and what this means for plant health and food safety. Recent experiments involving wheat and tomato have investigated microplastic behaviour and uptake under more environmentally realistic soil conditions, while researchers continue to emphasize the need for standardized testing and better understanding of real-world exposure levels.
