Although agricultural plastic film improves crop productivity, plastic residues in soil threaten soil quality and surrounding environment. With the weathering and farming practices, plastic residues are easily broken into small particles, such as microplastics which affect soil properties and plant performance. However, the knowledge of plastic film fragmentation and microplastics’ transport behaviour in soil has not well-addressed. Therefore, this research will focus on fragmentation processes of plastic film and microplastics’ transport either in field observation or in lab simulation. Based on the findings, constructive strategies will be explored to deal with (micro) plastic pollution in agricultural soil.
