Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
Summary
This review examines how microplastics affect soil microbial communities and plant systems in agricultural settings, documenting impacts on soil health, microbial diversity, and crop physiology. As microplastics accumulate in farmland soils through irrigation, sludge application, and plastic mulches, their effects on the soil ecosystem that underpins food production are a growing concern.
The overexploitation of plastics has come with the terrifying universal challenge of white pollution called microplastics (<5mm). The omnipresence, persistence, and transboundary dissemination of these microplastics (MPs) cause a serious threat to the whole ecosystem whether it is aero, aquatic, or terrestrial. However, the global monitoring data of MPs’ impact on the terrestrial ecosystem is far from sufficient, especially, in soil agroecosystems. So, it is vital that we develop a greater understanding of any potential harmful or adverse impacts of these pollutants on agroecosystems. To emphasize the gaps in our understanding of the nature and consequences of MPs in soil and soil-microbes-plant systems, this chapter will combine the currently available information on the presence, sources, and effects of MPs on several components of the agroecosystem, especially emphasizing the deleterious effect on soil, soil- microbes, and plant systems.

Microplastics in Agricultural Soils: An Emerging Threat to Soil Health, Microbial Ecology, Crop Productivity, and Food Safety
This review examines how microplastics accumulate in agricultural soils from sources like plastic mulch, sewage sludge, and atmospheric deposition. Researchers found that these particles can disrupt soil microbial communities, harm plant health, and potentially enter the human food chain. The study highlights the urgent need for mitigation strategies to address this growing but often overlooked form of pollution in farmland.
Microplastics in plant-microbes-soil system: A review on recent studies
This review examined microplastic interactions within the plant-microbe-soil system, finding that microplastics affect soil physicochemical properties, alter microbial communities, and can be taken up by plants, with implications for food safety and ecosystem health.
Microplastics in agroecosystems: A review of effects on soil biota and key soil functions
This review examines how microplastic and nanoplastic contamination in agricultural soils affects soil organisms and ecological functions. Researchers found that plastics enter farmland through multiple pathways including plastic mulch, sewage sludge, and irrigation water, and once present they alter soil properties and exhibit toxic behavior toward soil biota. The study identifies significant knowledge gaps about the long-term impacts of microplastic accumulation on agricultural productivity and food safety.
Microplastics in terrestrial ecosystem: Exploring the menace to the soil-plant-microbe interactions
This review summarizes existing research on how microplastics affect the complex relationships between soil, plants, and soil microbes. Microplastics alter soil structure, change the makeup of microbial communities, and disrupt beneficial partnerships between plants and helpful fungi and bacteria. These disruptions can reduce plant growth and nutrient cycling, which could ultimately affect crop yields and the quality of food produced on microplastic-contaminated farmland.
