Abstract: In recent years, the pollution of Microplastics (MPs) in agricultural soil has gradually received attention, and the environmental risks associated with it have become increasingly recognized. More and more studies on the impact of MPs on the agricultural soil environment have been conducted. This paper summarizes the research achievements and progress so far regarding MPs in agricultural soil, especially the progress in research on the impact of MPs on soil nutrients, the migration of heavy metals in soil, and soil enzyme activity. It also clarifies the current status and characteristics of research on MPs pollution in agricultural soil; discusses the main sources of MPs in farmland in China; and summarizes and analyzes the impact of MPs on the nutrients and migration of heavy metals in agricultural soil. The paper concludes that the sources of MPs in agricultural soil are diverse, and agricultural plastic film is one of the main sources of MPs in farmland, which has certain impact on soil nutrients, heavy metals, and soil enzyme activity. The paper also discusses the problems existing in the current research on MPs pollution in agricultural soil and presents prospects for future research.
Key words: Microplastics, farmland soil, soil nutrient
