Confirmation of Candidature - Candidate : Lenny Seo

Microplastics in the agricultural soil can be originated from various routes: application of biosolids and compost, irrigation, mulching film, fertilizers and pesticides, and atmospheric deposition. However, to date, there are few studies on microplastic impacts on agricultural soils, while microplastics in the marine environment have many comprehensive studies and data.  

Microplastics can alter soil structure, composition, and microbial activities. Soils are vital for food production, nutrient and water cycling, and supporting biodiversity. It also appears that the higher plants such as lettuce, garden cress and rice may be more negatively impacted when microplastics change soil properties. Thus, it is essential to develop a sound understanding of how microplastics accumulate in soil and their adverse impacts on soils. This project will investigate the impact of microplastics on agricultural soil and plant growth. This will be the first pioneering research of the impacts of microplastics on Australian agricultural soil and crops. This research is critical to ensure the safety of our food and the sustainability of soils which provides and regulates key ecosystem functions.
