Abstract:

The gradual accumulation of the microplastics (MPs, <5 mm) and nanoplastics (NPs, <1 μm) produced by crushing, weathering, and aging of plastic products in the soil as well as their difficult degradation characteristics have received widespread attention. Although the interactions between the MPs/NPs and plants in plant⁃soil relationships have been reported, there are fewer review papers regarding the emerging knowledge in this area. This hinders the sustained progress in this emerging field. This paper summarized the sources of MPs/NPs in agriculture, hazards, effects on soil properties and plant growth, and research techniques to complement them, and also describes the possible mechanisms about the phytotoxicity of MPs/NPs.

Key words: analytical techniques, agriculture, microplastic, nanoplastic
