Microplastic: Evaluating the Impact on Soil-Microbes and Plant System
AI summary Read the abstract
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 agroecosystems: A review of effects on soil biota and key soil functions
AI summary Read the abstract
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
AI summary Read the abstract
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.
