The Hidden Threat: How Plastic Pollution Is Affecting Soil Fertility
AI summary Read the abstract
Researchers examined how plastic waste in agricultural soils undergoes both abiotic fragmentation — from plowing, UV exposure, and weathering — and biotic transport through soil invertebrates and vertebrates, ultimately accumulating in plant root systems and entering the food chain in ways that threaten soil ecology and human consumers.
Plastic products for plant protection and cultivation increase agricultural yields, enhance food quality, reduce water use globally, and lessen environmental effect. Furthermore, plastic pollution is an important ecological concern because it has recently had a significant impact on soil, water, and vegetation. Both biotic and abiotic transport occur after plastic fragmentation in the soil. By plowing the ground and subjecting the plastic shards to water, wind, and UV light, for instance, a farmer can induce the plastic to break up into smaller pieces. The public is interested in the particles that they store in their root systems from the soil ecology. When vertebrates and macro, meso, and micro-invertebrates ingest and carry microplastics, MP transport takes place. The presence of plastic waste in the soil ecosystem is concerning because it can accumulate in plants cultivated in contaminated soils and affect consumers by directly entering the food supply chain. Plastic contamination in agriculture has a detrimental effect on soil ecology and plant growth. The public is interested in learning more about how plastic particles affect biomass quality and plant growth, as well as whether plants may absorb plastic particles from the soil environment and store them in their root systems.

Researchers reviewed how microplastics accumulate in soil from sources including sewage sludge, plastic mulch, and municipal wastewater, finding that these particles degrade soil physicochemical properties, disrupt microbial communities and enzyme activity, impair plant growth, and reduce fertilizer use efficiency.
Invisible threats in soil: Microplastic pollutionand its effects on soil health and plant growth
AI summary Read the abstract
This review summarizes current knowledge about microplastic contamination in agricultural soil, covering where the plastics come from, how they move through soil, and what they do to soil health and plant growth. Microplastics can alter soil structure, disrupt microbial communities, and interfere with nutrient cycles that plants need to grow. The findings raise concerns that widespread microplastic pollution in farmland could quietly reduce crop quality and productivity, ultimately affecting the food supply.
